Darn, got it. dyld: Library not loaded: /Volumes/Pear/xcode/Builds/Debug/ OmniNetworking.framework/Versions/A/OmniNetworking Referenced from: /Applications/MacTrek.app/Contents/MacOS/MacTrek Reason: image not found Despite the fact that the framework is available in the application bundle, it seems to be linked directly to the debug version in the builds directory. This is why you should never test on development machines. i'm on it Chris
