Re: [Qemu-devel] [PATCH] Improve Cocoa modifier key handling

[Programmingkid]

This patch is incompatible with anything below Mac OS 10.10. We support Mac OS 
10.5 and up. I was able to make this patch work on Mac OS 10.6 by changing this 
line:

NSEventModifierFlags modifiers = [event modifierFlags];

to this:

NSUInteger modifiers = [event modifierFlags];

This wouldn't be enough. The [event modifierFlags] code would have to be 
replaced because the modifierFlags function is not available on Mac OS 10.5.
