- On 10.6 and 10.7 System Preferences's 64-bit image requires GC. If the user opens a preference pane
that does not support GC System Preferences will restart as a 32-bit process, provided that the
preference pane has a 32-bit image.
- On 10.8+ System Preferences's 64-bit image supports GC but does not require it, and by default it
launches with GC disabled. If the user opens a preference pane that requires GC System Preferences
relaunches with GC enabled, but still as a 64-bit process.
So if your deployment target is <= 10.7 you'll get the best user experience by building with
GCC_ENABLE_OBJC_GC = supported, as the preference pane will run on all platforms without requiring a
