Well its about time they got rid of that X. Its been around since what. 2000??? Sounds like they should be on OSX 10.20 by not not 10.14/15 which ever it is haha.
And i wonder how this will affect the hackintosh market once they fully move to ARM on everything, even though I doubt that as the Mac Pro I can't see running on ARM anytime soo though, but just that "What If".
