Tweak AppCode font aliasing on your mac Jul 07, 2013
If you can't use your beloved Monaco font in AppCode because it has gained weight and simply looks too bold, you might want to trim your anti-aliasing settings.
Try running this in your terminal
$ defaults write com.jetbrains.AppCode.plist AppleFontSmoothing -int 1
Left one is updated and right one is original
You might tweak it even more by using different values for
-int 1 e.g. 0, 2 or 3. I'm not changing the system wide font smoothing setting, but only the one for AppCode.
