The primary problem I see is that a company that has a small but niche OS, refuses to support the major GPU company’s product. Given Win and Linux are the two major OS’s, Nvidia probably isn’t too fussed but from our narrow view of the world, the Mac OS seems important. When I look at the available hardware and OS options, it also doesn’t matter as the software I use is all cross platform and I prefer Nvidia GPUs so Apple are the loser in my case and for probably an increasing number of users.
Maybe Apple see it as way to niggle Adobe but Blackmagic clearly aren’t fussed. And surely Adobe will improve their performance on Macs. Again the problem is Apple’s attitude, expecting developers to adopt their standards and playing favourites. It’s one of the reasons they won’t be getting any money from me which I’m sure has them awake at night with worry. They better not get AMD offside or maybe then they will have sleepless nights. Meanwhile they are more focused on iPhone sales in China.
