Growl.framework/Versions/A/Growl: replacing existing signature
```
(BTW: I'm working with Xcode 4.3.1 and Growl 1.3.1) | I just spent the day working through the "bundle format unrecognized, invalid, or unsuitable" error when codesigning a framework. In my case I'm using XCode 4.6.1 and I was trying to code sign Qt frameworks.
First note that the Apple documentation ([TN2206](http://developer.apple.com/library/mac/technotes/tn2206/_inde... |
9,476,465 | I'm trying to submit a Mac app for Approval in the App Store, but linking with Growl is causing a validation error. I'm trying to re-codesign from the command line, but I'm getting the following error:
```
Ashs-MacBook-Pro:500px Uploader ash$ codesign -f -v -s "3rd Party Mac Developer Application: 500px Inc." ./Growl.... | 2012/02/28 | [
"https://Stackoverflow.com/questions/9476465",
"https://Stackoverflow.com",
"https://Stackoverflow.com/users/516359/"
] | Really strange, I've managed to resign the framework like this:
```
codesign -fs "3rd Party Mac Developer Application: Future Simple" Growl.framework/Versions/A/Growl
Growl.framework/Versions/A/Growl: replacing existing signature
```
(BTW: I'm working with Xcode 4.3.1 and Growl 1.3.1) | Would it be better if we shipped the sdk unsigned? It'd be a simple change, I'm hesitant to do so now since it's been like this for a little while. |
