- Forum: Mac OS X
It's not a question of if, but when. Problem is that ARM would be in addition to, not replacement of, x86, especially in desktops. And I doubt they'd pull a Rosetta and make an x86-to-ARM instruction translator, that would be wasteful and slow. Not sure Apple wants to go through that again. Regardless, let's keep in mind that OS X was running on Intel for 4 years before we ever heard about it, so OS X on ARM is likely to be a very long term project.
