I am still confused after reading the whole thread and several others on here and general internet about Mojave-Metal2 on MacPro5,1. I still do not know what Mojave-Metal2 GPU I need to buy.
This is extremely frustrating. I'd really would like to see a list of Metal2 GPU for MacPro5,1 for MacOS Mojave.
And I strongly believe Apple has a obligation to expand their official statement:
Mac Pro (Late 2013, plus mid-2010 and mid-2012 models with recommended Metal-capable GPU)
"Recommended" is in past tense. I've hunted all the web and do not see any GPU "recommended" from Apple anywhere.
It should not take more than 2 man-hours for Apple to put down a cogent purchaseable list. Which is less than the time I've been on the internet hunting for "recommended Metal-capable GPU."
So... get on it......
