An anonymous reader writes "Apple hasn't released a Mac OS X device running on ARM yet, but a recently discovered thesis from a former Apple intern going by the name of Tristan Schapp, details a 12 week project carried out in 2010 to port the OS to the ARMv5 architecture. The port got as far as booting to a multi-user prompt, but then hit hurdles to do with drivers and cache.
The good news is that same intern now works for Apple as part of the CoreOS team. With rumors last year that a MacBook Air running on ARM could appear by 2013, could he be part of a team making that happen? If he is, I bet it will use the new ARMv8 architecture announced late last year."Link to Original Source
