I am using MPB retina. I have more than two years of a constant osx experience but what I can't stand is an OSX font rendering. That's simply uncomfortable for my eyes. Big amount of my work I do using external monitor (Nec 24') and fonts look even more blurry (terrible) on it. Is there any official or unofficial way to change font rendering in OSX? Any kind of custom kexts or patching would be appreciated. I can't find myself anything wrt this.
You can use a lighter text rendering style by running
and quitting and reopening applications to apply the changes.
