Re: NSPrefrencePane with Garbage Collection won't work in System Preferences?
Sorry, you have confused me slightly (or perhaps given me false hope). I have 3 targets in my project: (1) the preference pane; (2) a framework; and (3) an application. 1 2 are both dual mode insofar as they can be compiled and run without garbage collection. #3, which doesn't interact with the System Prefs, but uses code out of the framework (#2), requires GC. I thought the point of supported versus required compile options for frameworks was that the first would support a GC app, but not require it, and the second would...well...require it. So, if a non-GC pref pane is loading a GC-Supported framework, shouldn't it be GC-free? Is the only way to do this to have entirely separate versions of the framework? (or just put the same code in each target separately and dispense with a a framework)?

Re: NSPrefrencePane with Garbage Collection won't work in System Preferences?
OK, I'm being dense today, but is it the case that the entire bundle is marked as GC-required if any piece of it requires GC? If I move the app out of the bundle (so it is just the Pane and the framework) does that make it no longer GC-required (if the Framework is compiled as GC-supported)? Again, the only parts of my code that touch the system prefs is the Pane and the framework, neither of which are compiled with GC-required.

Again, the only parts of my code that touch the system prefs is the Pane and the framework, neither of which are compiled with GC-required. The GC-ness marker applies to individual binaries, not bundle packages. So your framework can be marked GC-supported, even if it's inside an app bundle where the app's executable is marked GC- unsupported. You can use `otool` to verify the GC-ness of your binaries. If the value isn't what you want, double-check your compiler settings and make sure no wrong-GC files leaked in.
