my work computer is a 2013 macbook air, and i dual boot arch linux and osx. i'm not a mac guy by any means, so *nix on the air was a must for me. the only reason i dual boot is every once in a while i need the ios simulator to test a native app for one of our older clients.

arch runs very well on the mac, the only hickup was the wifi drivers (i had to install via usb ethernet). this guide spells everything out pretty well. i hightly suggest using the dkms wifi drivers from the AUR. just make sure you setup the dkms daemon to auto build on update or your wifi will not work when you get a new kernel.
