"From the listing, we can see that NVIDIA is working on software to allow its graphics processors to function properly in future Mac products.
In light of this, I wouldn't be surprised to see Apple choose NVIDIA graphics processors for future iMacs, MacBook Pros, or both. That said, we can't really infer much about potential timing of NVIDIA's inclusion in future Mac products from this job listing, if the company's chips are ultimately selected."
We can defiantly hope! The GTX 10-series are very impressive cards. That said nVidia has had a poor track record in the Mac. Heaps of bugs and relatively poor OpenCl performance. I also think the word on the street nVidia wasn't interested in a custom GPU for the MacPro-class machine.
I never really thought of them as having an aversion to NVIDIA. My Mac Pro 1,1 came with a terrible Geforce card stock, my rMBP (2013) has a Geforce discreet GPU, my new MacBook Pro has ATI cards, and my Mac Mini runs Intel. Each Macbook Pro I've owned (four at this point) has had what felt like a random ATI/NVIDIA card. Apple really doesn't seem married to one brand over the others, they've swapped back and forth several times in the ten-ish years since adopting Intel CPUs. Right now they seem to be entirely ATI, but I figured that was just because ATI had the best compute / power / price ratio at the time the machines came out. We're due for a refresh of almost the entire Mac line, and it wouldn't surprise me the least to see NVIDIA cards end up in a few of them.
