I left. My Mac Pro 4,1->5,1 is on eBay currently. It's become abundantly clear that Apple has no interest in supporting actual Pro machines, and just wants to sell headless iMacs that we can toss in the trash can anytime one component needs an upgrade. I'm not interested in that path. Also got very tired of playing their ******** game of "swap a card" anytime an OS update came out since Apple insists on using a built in nVidia driver from 5 years ago.
