https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKitOlderNotes/ In the “Notes specific to OS X 10.8”, see the section on NSButton/NSButtonCell, the second paragraph: "An NSButton configured as a radio button (with the -buttonType set to NSRadioButton), will now operate in a radio button group for applications linked on 10.8 and later. To have the button work in a radio group, use the same -action for each NSButton instance, and have the same superview for each button. When these conditions are met, checking one button (by changing the -state to 1), will uncheck all other buttons (by setting their -state to 0).” I don’t know if this describes exactly the conditions you’re seeing (no mention of 32-bit vs. 64-bit behavior, but perhaps you’re not using the same SDK for each architecture?). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
