Much as I respect and appreciate these efforts in maintaining compatible alternatives to canonical Mac OS X and Mac OS XI, in modern days I would prefer to run Mac OS X/XI applications in my GNU/Linux system over some compatibility layer (FoundationLibc, CorePulse, PicQuartz, Melkan, etc), because, in the years after leaving Mac OS X, I have establish new workflows which are mainly GNU-based.

I still want GarageBand and perhaps Processing / Glyph, but I prefer embedding those Mac OS X/XI apps in my GNU workflows. Rebooting to another OS wastes time and virtualization has performance penalty; neither is fun.
