screenshots would be nice, some people mention from time to time
problems with high DPI, but few of them show how it looks exactly.

Some time ago one of the users suggested adding NSPrincipalClass ->
NSApplication to Info.plist, which should have helped with retina
support, but we never got any solid confirmation what changed after I
did that. Also I think houz did some changes in git master which
concern UI scaling according to DPI setting, but I never tested that on
OS X.

See packaging/macosx/BUILD.txt. You have built gtk with X11 backend, I
use native quartz backend, which makes more sense to me.

I'm the only developer with Mac, and I don't have retina display, so no.

I didn't even know that it has any modes other than rootless... How do
you enter fullscreen mode?
