docker compose version
```

**For Other Linux Distributions**:
```bash
# Fedora/RHEL/CentOS
sudo dnf install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

# Arch Linux
sudo pacman -S docker docker-compose
```

**Post-Installation Steps**:
```bash
# Add your user to docker group (to run docker without sudo)
sudo usermod -aG docker $USER

# Enable Docker service
sudo systemctl enable docker
sudo systemctl start docker

# Log out and log back in for group changes to take effect
```

#### 2. Enable KVM

**Check KVM Support**:
```bash
# Check if KVM is supported
lscpu | grep Virtualization

# Check if KVM modules are loaded
lsmod | grep kvm

# Expected output:
# kvm_intel (for Intel CPUs) or kvm_amd (for AMD CPUs)
# kvm
```

**Enable KVM**:
```bash
# Install KVM packages (Ubuntu/Debian)
sudo apt-get install -y qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils

# For Fedora/RHEL/CentOS
sudo dnf install -y qemu-kvm libvirt virt-install bridge-utils

# Verify KVM is working
sudo kvm-ok

# Expected output:
# INFO: /dev/kvm exists
# KVM acceleration can be used
```

**Set KVM Permissions**:
```bash
# Add user to kvm group
sudo usermod -aG kvm $USER

# Verify /dev/kvm permissions
ls -l /dev/kvm

# Should show: crw-rw---- 1 root kvm

# Log out and log back in for group changes to take effect
```

**Verify KVM Access**:
```bash
# After logging back in, verify you can access KVM
groups | grep kvm

# Test KVM device access
test -r /dev/kvm && test -w /dev/kvm && echo "KVM is accessible" || echo "KVM access denied"
```

**If KVM is Not Enabled in BIOS**:
1. Restart your computer
2. Enter BIOS/UEFI settings (usually F2, F10, F12, or Del key during boot)
3. Look for virtualization settings:
   - Intel: "Intel VT-x" or "Intel Virtualization Technology"
   - AMD: "AMD-V" or "SVM Mode"
4. Enable the setting
5. Save and exit BIOS
6. Boot into Linux and verify with `kvm-ok`

### Docker Compose Deployment

**Recommended Deployment Method**: The **ONLY** recommended way to run this container is using Docker Compose. This ensures proper configuration and port mappings.

#### 1. Create Docker Compose File

Create a file named `deploy-macos.yaml`:

```yaml
services:
  mac-agent:
    image: nullvoider/mac15-base:v1
    container_name: mac_agent
    restart: unless-stopped
    tty: true
    stdin_open: true
    ports:
      - 4000:4000      # NoMachine (recommended remote access)
      - 4444:4445      # Eye server
      - 2222:2222      # SSH
      - 5900:5900      # VNC (temporary monitoring only)
      - 9090:9090      # Task Executor REST API
    environment:
      - API_TOKEN=your-secret-token
      - TASK_MAX_AGE=3600
    devices:
      - /dev/kvm:/dev/kvm
    cap_add:
      - NET_ADMIN
    extra_hosts:
      - "host.docker.internal:host-gateway"
```

#### 2. Deploy the Container

```bash
# Start the container
docker compose -f deploy-macos.yaml up -d

# View logs
docker compose -f deploy-macos.yaml logs -f

# Check container status
docker compose -f deploy-macos.yaml ps
```

#### 3. Container Management

```bash
# Stop the container
docker compose -f deploy-macos.yaml stop

# Start the container
docker compose -f deploy-macos.yaml start

# Restart the container
docker compose -f deploy-macos.yaml restart

# Remove the container
docker compose -f deploy-macos.yaml down

# Remove container and volumes
docker compose -f deploy-macos.yaml down -v
```

### Testing the Container

#### 1. Verify Container is Running

```bash
# Check container status
docker ps | grep mac_agent

# Expected output:
# CONTAINER ID   IMAGE                        STATUS          PORTS
# abc123def456   nullvoider/mac15-base:v1   Up 2 minutes    0.0.0.0:4000->4000/tcp, ...
```

#### 2. Check Boot Progress

```bash
# Monitor container logs
docker logs -f mac_agent

# Look for successful boot messages indicating:
# - macOS boot sequence completed
# - Services started
# - NoMachine server ready
# - VNC server ready
```

#### 3. Test Remote Access

**NoMachine (Recommended)**:
```bash
# Connect using NoMachine client to:
# Host: your-server-ip
# Port: 4000
```

**VNC (Temporary)**:
```bash
# Connect using any VNC client to:
# Host: your-server-ip
# Port: 5900
```

**SSH**:
```bash
# Test SSH connection
ssh -p 2222 user@your-server-ip
```

#### 4. Verify Services

Once connected via NoMachine or VNC:
1. Open Terminal
2. Check system information: `sw_vers`
3. Verify development tools: `python --version`, `node --version`, etc.
4. Open VS Code to verify it's installed

#### 5. Health Check

```bash
# Check container resource usage
docker stats mac_agent

# Expected metrics:
# CPU: 20-30% (normal workload)
# MEM: ~4GB allocated
# NET I/O: Varies based on remote access usage
```

## Customizing the Image

This section walks through the full process of modifying the macOS environment and rebuilding a custom Docker image — useful for adding languages, tools, updated scripts, or any workflow-specific configurations and customizations.

### Prerequisites

- Repository cloned
- Docker and QEMU utilities installed (`qemu-img` must be on PATH)
- At least 100 GB free disk space for the conversion steps

---

### Step 1 — Modify the YAML Configuration (Optional)

If you need to adjust the RAM or CPU core allocation before booting into macOS, edit the YAML file inside the `scripts/` directory of the cloned repo:

```bash
# Example: open and edit the YAML before moving it
nano scripts/mac15.yaml
```

Then move it to a separate working directory of your choice — this directory will be your build workspace for all subsequent steps:

```bash
mv scripts/mac15.yaml /your/working/directory/
```

> ⚠️ **WARNING**: Only change RAM and CPU core values in the YAML. **Do not change the disk size** — altering the disk size will corrupt `data.img` and make it unusable. If that happens, you will need to re-run Step 2 from the original QCOW2 file to start over.

---

### Step 2 — Convert the QCOW2 to a Raw Image

From the root of the cloned repository, convert the QCOW2 disk image to a raw format that QEMU can use as a mutable disk:

```bash
qemu-img convert -p -f qcow2 -O raw mac15-image/mac15.qcow2 data.img
```

This may take several minutes depending on your disk speed. The `-p` flag shows progress.

---

### Step 3 — Create the macOS Directory Structure

Navigate to the working directory where you moved the YAML file and create the expected directory layout:

```bash
cd /your/working/directory
mkdir macos
mkdir macos/15
```

---

### Step 4 — Place the Disk Images

Copy or move `base.dmg` and the `data.img` produced in Step 2 into the directory you just created:

```bash
# Copy (safe — preserves originals)
cp /path/to/base.dmg macos/15/base.dmg
cp /path/to/data.img macos/15/data.img

# Or move (saves disk space if originals are no longer needed)
mv /path/to/data.img macos/15/data.img
```

---

### Step 5 — Boot and Customize

Start the container from your working directory:

```bash
docker compose -f mac15.yaml up -d
```

Connect via NoMachine or VNC and perform your customizations inside the running macOS environment — updating the Task Executor script, installing apps, adding programming languages, configuring tools, or anything else your workflow requires.

---

### Step 6 — Clean Up Before Capture

Before shutting down, ensure the macOS environment is clean so no personal or session data ends up in your image:

- **Browser**: Close all tabs and clear all browsing history, cookies, and cached data in every browser installed
- **Terminal**: Wipe shell history — in the terminal run `history -c && > ~/.zsh_history && > ~/.bash_history`
- **Recent items**: Clear recent files, recent apps, and recent servers from the Apple menu → Recent Items → Clear Menu
- **Trash**: Empty the Trash

---

### Step 7 — Shut Down and Stop the Container

Shut down macOS cleanly from within the OS (Apple menu → Shut Down) and wait for the guest to fully power off. Then, from the host terminal in your working directory:

```bash
docker compose -f mac15.yaml down
```

---

### Step 8 — Convert Back to QCOW2

From the `macos/15/` directory, convert the modified raw image back to a compressed QCOW2:

```bash
cd macos/15
qemu-img convert -p -O qcow2 -c data.img mac15.qcow2
```

The `-c` flag enables compression to keep the image size manageable. This step may take several minutes.

---

### Step 9 — Move the QCOW2 to the Build Directory

Move the new QCOW2 back into the `mac15-image/` directory of the cloned repository. If a QCOW2 already exists there, remove it first:

```bash
# Remove existing if present
rm /path/to/cloned-repo/mac15-image/mac15.qcow2

# Move new QCOW2 into place
mv macos/15/mac15.qcow2 /path/to/cloned-repo/mac15-image/mac15.qcow2
```

---

### Step 10 — Build Your Custom Image

From the root of the cloned repository, build the Docker image with your chosen tag:

```bash
docker build -f mac15-base.dockerfile -t <username>/<image-name>:<version-number> .
```

Example:
```bash
docker build -f mac15-base.dockerfile -t myorg/mac15-custom:v1 .
```

Once the build completes, clear the Docker builder cache to avoid storage bloat:

```bash
docker builder prune --all
```

Your custom image is ready to use in your workflow.

## The-Eye Integration

The Eye is an AI-native vision capture tool integrated into the macOS container, providing automated screen capture capabilities for Computer Use Agent training, monitoring, and debugging.

### Overview

The Eye captures screen content at configurable intervals for:
- **Agent Training**: Collect visual data for training CUAs, train coding agents with full environment rather than a partial one and also evaluate agents in a full OS environments
- **Debugging**: Record agent interactions for troubleshooting
- **Monitoring**: Track agent behavior during execution
- **Dataset Creation**: Build machine learning datasets from screen captures

### Configuration

**Eye Server Port**: 8080 (HTTP)  
**Architecture**: Client-server model with RESTful API  
**Storage**: In-memory circular buffer (configurable capacity)

**Important Note**: The Eye server configuration is specific to the macOS container. Server port and settings differ from the Ubuntu build, though core functionality remains the same.

### Connection & Endpoints

**Eye Server Base URL**:
```
http://your-server-ip:8080
```

**Available Endpoints**:
- `GET /health` - Server health status and metrics
- `GET /snapshot.png` - Retrieve latest captured frame
- `POST /upload` - Upload captured frames (for external agents)
- `POST /admin/config` - Update capture configuration
- `GET /debug` - Server runtime statistics

### Python SDK

The Eye includes a Python SDK for programmatic access:

**Installation** (if not using container's built-in Eye):
```bash
pip install eye-capture
```

**Basic Usage**:
```python
from eye.core import EyeClient

# Connect to Eye server
client = EyeClient("http://localhost:8080", token="your-token")

# Health check
health = client.health_check()

# Get latest screenshot
image_data = client.get_snapshot()
with open("screenshot.png", "wb") as f:
    f.write(image_data)

# Get frame metadata
metadata = client.get_snapshot_metadata()
print(f"Frame ID: {metadata['frame_id']}")

# Get debug info
debug = client.get_debug_info()
print(f"Uptime: {debug['uptime_sec']}s")
```

**Advanced Features**:
```python
from eye.core import EyeClient, SessionManager
from eye.integrations import DatasetExporter

# Initialize components
client = EyeClient("http://localhost:8080", token="TOKEN")
exporter = DatasetExporter()

# Capture session
for i in range(100):
    frame = client.get_snapshot()
    metadata = client.get_snapshot_metadata()
    exporter.add_frame(frame, i, metadata)
    time.sleep(1.5)

# Export dataset
exporter.export_json("training_data.json")
exporter.export_csv("training_data.csv")
```

### Key Features

**Capture Capabilities**:
- Multiple image formats (PNG, JPEG, WebP, BMP, TIFF)
- Configurable quality (1-100)
- Adjustable capture interval (0.1s minimum)
- Automatic retries with exponential backoff

**API Features**:
- RESTful HTTP endpoints
- Token authentication
- Dynamic configuration updates
- Health monitoring
- Debug statistics

**Integration Options**:
- Python SDK for programmatic access
- REST API for any language
- Dataset export (JSON, JSONL, CSV)
- Webhook support for event notifications
- Cloud storage integration patterns

### Quick Usage Examples

**REST API (curl)**:
```bash
# Get latest screenshot
curl http://localhost:8080/snapshot.png > screenshot.png

# Check health
curl http://localhost:8080/health

# Update configuration
curl -X POST http://localhost:8080/admin/config \
  -H "Authorization: Bearer your-token" \
  -d '{"interval": 2.0, "format": "jpeg", "quality": 85}'
```

**Python SDK**:
```python
from eye.core import EyeClient

client = EyeClient("http://localhost:8080")

# Continuous monitoring
while True:
    snapshot = client.get_snapshot()
    # Process snapshot for agent training
    process_for_training(snapshot)
    time.sleep(1.5)
```

### Performance Impact

- **CPU Overhead**: <3% during capture
- **Memory Usage**: 50-150 MB (in-memory buffer)
- **Network Bandwidth**: 0.5-2 MB/s @ 1.5s interval
- **Capture Latency**: 10-50ms (platform dependent)
- **Display Performance**: No noticeable impact on macOS GUI

### Configuration Options

The Eye service runs automatically when the container starts. Configure via API:

```python
import requests

# Update capture settings
response = requests.post(
    "http://localhost:8080/admin/config",
    headers={"Authorization": "Bearer your-token"},
    json={
        "interval": 2.0,      # Capture every 2 seconds
        "format": "jpeg",     # Use JPEG format
        "quality": 85         # 85% quality
    }
)
```

## Task Executor REST API
 
The Task Executor is a Flask/waitress HTTP service running directly inside the macOS QEMU guest, exposed on **port 9090** via QEMU port-forwarding. It provides structured task submission and result retrieval for coding agents and evaluation harnesses, including SWE-bench Lite compatibility.
 
### Architecture
 
```
[external client]
    │  HTTP  port 9090
    ▼
[QEMU port-forward  hostfwd tcp::9090-:9090]
    ▼
[Flask service — running natively inside macOS guest]
    │  subprocess / native macOS calls
    ▼
[git, python3, pytest — all native on macOS]
```
 
**Important**: `docker exec` cannot reach the macOS QEMU guest. All task execution must go through this REST API or SSH (port 2222). Never use `docker exec mac_agent <cmd>` to run commands inside macOS.
 
### Service Setup (one-time, via SSH)
 
```bash
# 1. Copy files into the guest
scp -P 2222 task_executor.py AgentUser@localhost:/Users/AgentUser/tasks/
scp -P 2222 com.cua.taskexecutor.plist AgentUser@localhost:/Users/AgentUser/tasks/
 
# 2. SSH in and complete setup
ssh -p 2222 AgentUser@localhost
 
# 3. Install dependencies
pip3 install flask waitress
 
# 4. Register as a launchd system service (auto-starts on boot)
sudo cp /Users/AgentUser/tasks/com.cua.taskexecutor.plist /Library/LaunchDaemons/
sudo chown root:wheel /Library/LaunchDaemons/com.cua.taskexecutor.plist
sudo chmod 644 /Library/LaunchDaemons/com.cua.taskexecutor.plist
 
# 5. Start immediately without rebooting
sudo launchctl load /Library/LaunchDaemons/com.cua.taskexecutor.plist
```
 
Service logs are written to `/Users/AgentUser/tasks/task_executor.log`.
 
### Endpoints
 
#### POST /task/submit
 
Submit a task for execution. Returns immediately with a task ID.
 
**Request body**:
```json
{
  "repo_url":        "https://github.com/org/repo",
  "base_commit":     "abc1234",
  "patch":           "--- a/file.py\n+++ b/file.py\n...",
  "test_command":    "python3 -m pytest tests/ -x --tb=short",

| `capture_diff` | ❌ | `false` | Capture `git diff <base_commit>` after tests |
| `reference_patch` | ❌ | — | Ground-truth unified diff for patch similarity scoring |
 
**Response** `202 Accepted`:
```json
{ "task_id": "550e8400-e29b-41d4-a716-446655440000", "status": "pending" }
```
 
#### GET /task/{id}
 
Lightweight status poll — no stdout/stderr payload.
 
**Response** `200`:
```json
{ "task_id": "...", "status": "pending|running|completed|failed" }
```
 
#### GET /task/{id}/result
 
Full result once the task completes. Returns `202` while still running.
 
**Response** `200`:
```json
{
  "task_id":          "...",
  "status":           "completed",
  "exit_code":        0,
  "stdout":           "...",
  "stderr":           "...",
  "tests_passed":     5,
  "tests_failed":     0,
  "lint_errors":      2,
  "lint_output":      "Found 2 errors.",
  "patch_diff":       "diff --git a/src/foo.py ...",
  "patch_similarity": 0.9412,
  "execution_time":   14.2
}
```
 
#### DELETE /task/{id}
 
Remove a task record from the store.
 
**Response** `200`:
```json
{ "task_id": "...", "deleted": true }
```
 
### SWE-bench Lite Compatibility
 
The task executor is designed to be compatible with the [SWE-bench Lite](https://github.com/princeton-nlp/SWE-bench) evaluation harness:
 
- **Clean workspace per task**: Each task runs in its own UUID subdirectory (`/Users/AgentUser/tasks/<uuid>/repo/`). No git state is shared between tasks — no VM reboot required.
- **Pinned base commit**: The `base_commit` field maps directly to the SWE-bench instance's `base_commit`.
- **Patch application**: The `patch` field accepts a standard unified diff, applied via `git apply` after checkout.
- **pytest execution**: `test_command` accepts any pytest invocation; pass/fail counts are parsed from output automatically.
- **Structured results**: Exit code, stdout, stderr, pass/fail counts, and execution time are all returned in a single JSON response.
**Example SWE-bench task submission**:
```bash
curl -X POST http://localhost:9090/task/submit \
  -H "Content-Type: application/json" \
  -d '{
    "repo_url":     "https://github.com/psf/requests",
    "base_commit":  "a1b2c3d4",
    "patch":        "<unified diff from SWE-bench instance>",
    "test_command": "python3 -m pytest tests/test_requests.py -x --tb=short",
    "timeout":      600
  }'
```
 
### Supported Test Frameworks

The executor auto-detects the test framework from `test_command` and routes to the appropriate parser.

| `test_command` contains | Framework | Output parsed |
|------------------------|-----------|--------------|
| `pytest`, `py.test` | pytest | `5 passed, 2 failed, 1 error in 3.14s` |
| `cargo` | cargo test | `test result: ok. 5 passed; 0 failed` |
| `go test` | go test | `--- PASS/FAIL:` lines; `ok`/`FAIL` package lines |
| `jest`, `npm test`, `yarn test`, `pnpm test` | Jest | `Tests: 2 failed, 5 passed, 7 total` |
| `dotnet` | dotnet test | `Failed: 2, Passed: 3, Total: 5` |
| `mvn`, `gradle`, `sbt`, `junit` | JUnit/Surefire | `Tests run: 7, Failures: 2, Errors: 0` |

For unrecognised commands, all parsers are tried in order and the first non-zero result is used.

### Supported Linters (Soft Score)

Lint results are recorded in `lint_errors` and `lint_output` but **never** change `status` or `exit_code`. This is consistent with SWE-bench, HumanEval, and LiveCodeBench conventions.

| Linter | Language | Example `lint_command` |
|--------|----------|------------------------|
| `ruff` | Python | `ruff check . --output-format json` |
| `flake8` | Python | `flake8 src/` |
| `mypy` | Python | `mypy src/ --ignore-missing-imports` |
| `pylint` | Python | `pylint src/` |
| `cargo clippy` | Rust | `cargo clippy -- -D warnings` |
| `eslint` | JS/TS | `eslint src/ --format json` |
| `go vet` | Go | `go vet ./...` |
| `clang-tidy` | C/C++ | `clang-tidy src/*.cpp` |
| `dotnet build` | C# | `dotnet build --no-restore` |

### API Authentication

When `API_TOKEN` is set (via environment variable in the macOS guest or the Docker Compose file), every request must include:

```
Authorization: Bearer <token>
```

Requests without a valid token return `401 Unauthorized`. Set it via SSH before starting the executor:

```bash
ssh -p 2222 AgentUser@localhost
export API_TOKEN=your-secret-token
python3 /Users/AgentUser/tasks/task_executor.py &
```

Or set it persistently in the launchd plist:
```xml
<key>EnvironmentVariables</key>
<dict>
    <key>API_TOKEN</key>
    <string>your-secret-token</string>
    <key>TASK_MAX_AGE</key>
    <string>3600</string>
</dict>
```

### Cleanup After Testing
 
To remove all traces of the task executor from the macOS guest:
 
```bash
ssh -p 2222 AgentUser@localhost
 
# Stop and unload the service
sudo launchctl unload /Library/LaunchDaemons/com.cua.taskexecutor.plist
 
# Remove the plist
sudo rm /Library/LaunchDaemons/com.cua.taskexecutor.plist
 
# Remove the script, log, and any remaining task directories
rm -rf /Users/AgentUser/tasks
 
# Uninstall dependencies
pip3 uninstall flask waitress -y
```

## Troubleshooting

### Common Issues

#### 1. Dock Not Appearing

**Symptoms**:
- macOS dock is missing after boot
- Desktop appears but dock doesn't load
- Dock was visible before but disappeared

**Causes**:
- Docker not releasing RAM/CPU completely
- macOS process management issue
- System resource constraints

**Solutions**:

**Option 1: Restart Container** (Try This First)
```bash
# Stop the container
docker compose -f deploy-macos.yaml stop

# Wait 10 seconds
sleep 10

# Start the container
docker compose -f deploy-macos.yaml start

# Monitor logs
docker logs -f mac_agent
```

**Option 2: Restart Docker Service**
```bash
# Restart Docker service
sudo systemctl restart docker

# Wait for Docker to fully restart
sleep 15

# Start the container
docker compose -f deploy-macos.yaml up -d
```

**Option 3: System Restart** (If Above Don't Work)
```bash
# If Docker doesn't release resources properly, a system restart may be necessary
sudo reboot
```

**Prevention**:
- Ensure adequate system RAM free (8GB recommended)
- Don't run too many containers simultaneously
- Monitor host system resources regularly
- Perform clean container shutdowns

#### 2. Slow Performance During Animations

**Symptoms**:
- Lag during window transitions
- Slow animations
- Choppy GUI movements
- Applications with heavy animations slow down other apps

**Cause**:
- Intel i3 CPU configuration limits animation performance
- Current configuration optimized for stability, not animation speed

**Solutions**:

**Option 1: Reduce Animations in macOS**
1. Open System Preferences
2. Go to Accessibility → Display
3. Enable "Reduce motion"
4. Disable "Reduce transparency" if needed

**Option 2: Close Animation-Heavy Applications**
- Avoid running multiple apps with complex animations
- Close unnecessary applications
- Focus on development tools without heavy UI effects

**Option 3: Configuration Adjustment** (Advanced)
- The current i3 configuration is based on tested and confirmed settings
- Configuration can be customized for better animation performance
- Requires understanding of system limits and testing
- Contact for configuration guidance if needed

**Note**:
- Regular development workloads run smoothly
- Issue only affects excessive animation scenarios
- Normal coding, browsing, and terminal work unaffected

#### 3. Container Won't Start

**Symptoms**:
- Container exits immediately after start
- Error messages in logs
- Container status shows "Exited"

**Diagnostic Steps**:
```bash
# Check container logs
docker logs mac_agent

# Check container status
docker ps -a | grep mac_agent

# Inspect container
docker inspect mac_agent
```

**Common Solutions**:

**KVM Not Available**:
```bash
# Verify KVM is accessible
ls -l /dev/kvm

# Check if you're in kvm group
groups | grep kvm

# Add user to kvm group if missing
sudo usermod -aG kvm $USER
# Log out and back in
```

**Insufficient Resources**:
```bash
# Check available RAM
free -h

# Check disk space
df -h

# Verify at least 4GB RAM available
```

**Port Conflicts**:
```bash
# Check if ports are already in use
sudo netstat -tlnp | grep -E '4000|4444|2222|5900|9090'

# Stop conflicting services or change ports in docker-compose.yaml
```

#### 4. Remote Access Connection Issues

**NoMachine Won't Connect**:
```bash
# Verify port is exposed
docker port mac_agent 4000

# Check if service is listening
docker exec mac_agent netstat -an | grep 4000

# Test connectivity from host
telnet localhost 4000
```

**VNC Not Working**:
```bash
# Check VNC port
docker port mac_agent 5900

# Verify VNC server is running
docker exec mac_agent ps aux | grep vnc
```

**SSH Connection Refused**:
```bash
# Check SSH port mapping
docker port mac_agent 2222

# Verify SSH service
docker exec mac_agent ps aux | grep sshd
```

#### 5. macOS-Specific Issues

**Standard macOS Troubleshooting Applies**:

Most macOS-related issues can be resolved using standard macOS troubleshooting methods:

1. **System Preferences Reset**:
   - Open System Preferences
   - Reset specific settings causing issues
   - Restart affected applications

2. **Application Issues**:
   - Force quit misbehaving applications
   - Clear application caches
   - Reinstall problematic applications via Homebrew

3. **Disk Issues**:
   - Run Disk Utility
   - Verify and repair disk if needed
   - Check available storage space

4. **Permission Issues**:
   - Reset permissions in System Preferences
   - Use `chmod` and `chown` as needed
   - Check application permissions in Security & Privacy

**These are standard macOS issues, not container-specific problems**.

### Getting Help

If you encounter issues not covered here:

1. **Check container logs**: `docker logs mac_agent`
2. **Review system resources**: Ensure minimum requirements are met
3. **Verify KVM access**: Confirm `/dev/kvm` is accessible
4. **Test connectivity**: Check network and port accessibility
5. **See Reporting Issues section** for how to get support

## FAQ

### Coding Agent Evaluation Questions

**Q: What new eval capabilities were added in v1?**
A: The Task Executor API now supports `lint_command` (soft-score linting), `capture_diff` (records `git diff <base_commit>` after the test run), and `reference_patch` (ground-truth unified diff for patch similarity scoring returning a 0.0–1.0 ratio). Multi-framework test scoring covers pytest, cargo, go test, jest, dotnet, and JUnit/Maven/Gradle/sbt — auto-detected from `test_command`. See the [Task Executor REST API](#task-executor-rest-api) section for full field reference.

**Q: Why is lint scoring soft — why doesn't it fail the task?**
A: The majority of established coding benchmarks (SWE-bench, HumanEval, LiveCodeBench) use test pass/fail as the primary correctness signal. Lint errors reflect code quality but not functional correctness. Keeping lint as a soft score lets you track quality trends without invalidating otherwise correct solutions.

**Q: What is patch_similarity and when is it useful?**
A: It is a 0.0–1.0 similarity ratio between the agent's actual diff and a ground-truth reference patch, computed after stripping all unified diff metadata (file paths, line numbers, git object hashes). Most useful for patch-apply evals where a canonical solution exists. Always interpret alongside `tests_passed` — a lower similarity score does not mean the solution is wrong.

**Q: How do I access the Task Executor API remotely from outside the container?**
A: The Task Executor runs inside the macOS QEMU guest and is forwarded to the Docker host via QEMU's `hostfwd` on port 9090. From outside the host, it is reachable at `http://your-server-ip:9090` as long as port 9090 is exposed in the Compose file (which it is by default). Always set `API_TOKEN` when the port is reachable outside a trusted network boundary.

**Q: In a k8s deployment with many replicas, how does an orchestrator target a specific pod?**
A: Each replica runs its own Task Executor with its own in-memory task store. The orchestrator must track the pod IP (or headless service DNS entry) at submission time and send all status/result polls to the same pod — a load-balanced service may route to a different replica and return `404 Task not found`. Use a headless k8s service to get per-pod DNS entries, or record the pod IP at submission time.

**Q: What happens to in-flight tasks if a pod is evicted or restarted?**
A: Tasks are in-memory inside the macOS guest and are lost on restart. The macOS container's ~4-second boot means recovery is fast, but the orchestrator must still implement retry logic and treat `404 Task not found` as a signal to resubmit.

**Q: How do I pass API_TOKEN securely in a k8s deployment?**
A: Mount it as a k8s Secret and inject it into the launchd plist environment via an init container or startup script. Never hardcode tokens in the Compose file or Dockerfile:
```yaml
env:
  - name: API_TOKEN
    valueFrom:
      secretKeyRef:
        name: task-executor-secret
        key: api-token
```

**Q: Can the Task Executor run tasks in parallel?**
A: Yes — each submitted task runs in an independent background thread with its own isolated UUID workspace under `/Users/AgentUser/tasks/`. Tasks never share git state. For large-scale parallelism, deploy multiple container replicas via k8s; each replica maintains its own in-memory store.

### General Questions

**Q: Can I use this container for coding agent evaluation like SWE-bench?**
A: Yes. The Task Executor REST API (port 9090) provides exactly the interface needed: submit a repo URL, base commit, patch, and test command; poll for status; retrieve structured results including exit code, stdout, stderr, and pytest pass/fail counts. Each task gets an isolated UUID workspace so concurrent tasks and sequential tasks never share state. See the [Task Executor REST API](#task-executor-rest-api) section for full setup and usage.
 
**Q: Why can't I use `docker exec mac_agent <command>` to run commands inside macOS?**
A: This container runs macOS inside a QEMU virtual machine. `docker exec` executes commands on the Ubuntu Docker host layer, not inside the macOS guest. To run commands in macOS, use SSH on port 2222 or the Task Executor REST API on port 9090.

**Q: How is the entire macOS system running in a single container?**  
A: This container uses advanced virtualization techniques with KVM acceleration to run a complete macOS system. Unlike Dockur and Docker-OSX which require multiple external files and complex setups, this build has everything self-contained within the container image, the result is a fully functional macOS 15.7.5 environment that's completely isolated and ephemeral.

**Q: Why doesn't this container need external files like Dockur and Docker-OSX?**  
A: The container architecture was designed from the ground up to be self-contained. All necessary components, including the macOS system files, bootloader, and configuration, are embedded within the container image itself. This provides significant advantages: easier deployment, cleaner state management, no external file dependencies, and true ephemeral operation.

**Q: What makes this container different from Docker-OSX and Dockur?**  
A: Several key differences:
- **No External Files**: Everything is self-contained in the container
- **Better Performance**: 20-30% CPU usage vs higher overhead in alternatives
- **Smoother Operation**: Optimized for stability and responsiveness
- **Ephemeral State**: Clean isolation without external dependencies
- **Simpler Deployment**: Just Docker Compose, no complex file management
- **Customizable**: Configuration can be tuned for specific hardware

**Q: Can I run multiple instances of this container?**  
A: Yes, but each instance requires 4GB of RAM. Ensure your host has sufficient resources (e.g., 8GB+ RAM for 2 instances).

**Q: How much disk space does it need?**  
A: The container image requires approximately 100GB of host disk space. The macOS system inside has a 4TB virtual disk.

**Q: Is this suitable for production use?**  
A: Yes, it's specifically designed for Computer Use Agent development and deployment in production environments. The container provides a stable, reproducible macOS environment ideal for CI/CD pipelines and automated testing. **Important**: For production use, ensure compliance with Apple's Software License Agreement (EULA), as commercial deployment of macOS may have specific licensing requirements.

### Performance Questions

**Q: What is the boot time?**  
A: The container is ready in approximately 30 seconds — the macOS system and all services (NoMachine, Task Executor, Eye) are live immediately after the container starts. This is one of the key advantages over Dockur and Docker-OSX alternatives.

**Q: Can I improve the performance?**  
A: Yes, the current Intel i3 CPU configuration can be customized for better performance based on your hardware. The existing configuration prioritizes stability and compatibility. For better animation performance, you can adjust the CPU configuration, though this requires testing on your specific hardware.

**Q: Why does NoMachine perform better than VNC?**  
A: NoMachine uses hardware acceleration, optimized protocols, and better compression algorithms specifically designed for remote desktop performance. VNC uses a more basic protocol that's less efficient for macOS GUI rendering.

**Q: What's the CPU usage under heavy load?**  
A: Under normal development workloads (coding, browsing, terminal work), expect 20-30% CPU. Heavy compilation or animation-intensive applications may increase this to 40-50%.

### Compatibility Questions

**Q: Does it work on Windows/macOS hosts?**  
A: It requires a Linux host with KVM support. Windows (WSL2 with nested virtualization) and macOS hosts are not officially supported due to KVM requirements.

**Q: What Linux distributions are supported?**  
A: Any modern Linux distribution with Docker 24.0+ and KVM support:
- Ubuntu 20.04+
- Debian 11+
- Fedora 36+
- CentOS 8+
- Arch Linux

**Q: Can I use AMD CPUs?**  
A: Yes, as long as AMD-V (SVM) is enabled in BIOS and the KVM kernel modules are loaded.

**Q: What about ARM processors (Apple Silicon)?**  
A: Not supported. This is an x86_64 container designed for Intel/AMD processors only.

### Configuration Questions

**Q: Can I change the RAM allocation?**  
A: The container is configured for 4GB RAM. Changing this requires rebuilding the container image with modified configuration. This is not recommended without thorough testing.

**Q: How do I add more software to the container?**  
A: Use Homebrew inside the running container:
```bash
brew install package-name
```
For persistence, create a custom image based on this one.

**Q: Can I use this for iOS app development?**  
A: Xcode command line tools are available, but full Xcode IDE may require additional configuration. The container is optimized for Computer Use Agent development.

**Q: How do I persist data across container restarts?**  
A: Use Docker volumes to mount directories from the host:
```yaml
volumes:
  - ./my-projects:/Users/username/projects
```

### Remote Access Questions

**Q: Why can't I use VNC for development work?**  
A: VNC performance is significantly lower than NoMachine. It's suitable only for monitoring or quick checks. For actual development work, the lag and lower frame rate make it impractical.

**Q: Can I use other remote desktop solutions?**  
A: The container is pre-configured with NoMachine and VNC. Adding other solutions would require custom configuration.

**Q: What's the bandwidth requirement for NoMachine?**  
A: Minimum 10 Mbps, recommended 100 Mbps+ for best experience. Less bandwidth will work but may impact video quality.

### Troubleshooting Questions

**Q: The dock isn't appearing. What should I do?**  
A: First try restarting the container. If that doesn't work, restart the Docker service. In rare cases, a system restart may be needed to fully release resources.

**Q: Why are animations slow?**  
A: The Intel i3 CPU configuration prioritizes stability. You can reduce animations in macOS settings or customize the CPU configuration for better animation performance.

**Q: How do I access container logs?**  
A:
```bash
docker logs mac_agent
docker logs -f mac_agent  # Follow mode
```

**Q: The container won't start. What's wrong?**  
A: Check:
1. KVM is accessible (`ls -l /dev/kvm`)
2. Sufficient RAM available (8GB free)
3. Ports aren't conflicting
4. Docker service is running
5. Container logs for specific errors

### Security Questions

**Q: Is this container secure?**  
A: The container runs with NET_ADMIN capability and requires KVM access. It's designed for development environments. For production, review security considerations and implement appropriate network isolation.

**Q: Can I run this in a public cloud?**  
A: Only on infrastructure that exposes hardware virtualization extensions to the guest. Bare-metal instances work universally. Standard VM instances require the cloud provider to explicitly enable nested virtualization — AWS Nitro, Google Cloud, and Azure support it on select instance types, but it must be enabled per-instance and is not on by default. The limiting factor is the hypervisor configuration, not the host OS.

**Q: How do I secure remote access?**  
A: Use VPN or SSH tunneling to access the container:
```bash
ssh -L 4000:localhost:4000 -p 2222 host-server
```
Then connect NoMachine to `localhost:4000`.
