Is LTX-2 compatible with Mac M4/Metal?
Hi everyone,
I'm trying to run the LTX-2.0 Text to Video workflow in ComfyUI but I keep getting a "Reconnecting" status (see screenshot). The workflow never starts processing.
My Setup:
Mac: MacBook Pro with Apple M4 Max
Chip: 16 cores (12 performance + 4 efficiency)
GPU: 40-core Apple M4 Max GPU with Metal 4 support
RAM: 48 GB unified memory
OS: macOS Sequoia
Workflow Settings:
Frame count: 121
Width: 1280
Height: 720
Noise seed: 10
Checkpoint: ltx-2-19b-dev-fp8.safetensors
What I've tried:
Running the default sample workflow that comes with LTX-2 (no custom modifications)
Using the default prompt and settings provided
Feed the error from your terminal output into ChatGPT or Claude. They'll give you a good sense of what's going on, usually.
fp8 models don't work on metal...change the model to b16 or a gguf
