Intel's integrated graphics hardware is used extensively throughout the Mac product line, while discrete Nvidia and AMD graphics processors are used on some systems like some 15-inch MacBook Pros, higher-end iMacs and the Mac Pro. That includes graphics hardware made by Intel, Nvidia and AMD. iMac Retina 5K, 27-inch (late 2013 and later).MacBook Pro 15-inch Retina (Mid 2012 and later).MacBook Pro 13-inch Retina (Late 2012 and later).MacBook Air 13-inch (Mid 2012 and later).

I hate to go to a Windows box, but it is something on the table as an option for now. IF Redshift does get this done within the next few months, that would allow me to jump up to an iMac Pro most likely. He wants to ramp up the amount of animations we're doing and some video editing. But right now I'm on the fence about what to get. My boss also wants to get better hardware for me at work soon, so my renders will go faster. At that point I could see letting go of the Nvidia card and getting an AMD card. So if that becomes a reality, it will be a huge deal for Mac people that want to render using the GPU. They didn’t want to give an exact date, but they guessed sometime in the first quarter of 2020 is when it will be released. Redshift has said they are porting over their software to also work on AMD GPU's (which would include Metal capable cards) and in their forums they said they are pretty close to having it finished. But that would mean no Octane and no Redshift. So it's either I stick with the GTX 1080 or sell it and go AMD. I thought about swapping the card out for an RX580. It is annoying that Apple dropped support for these, but I guess that's just Apple being Apple. I wanted to use it for CUDA rendering (Redshift, Octane). I bought the Nvidia card back when it was still supported by Web Drivers with no clue that Apple would drop support for it in future OS's.
