Alright, I'm mad. Well, maybe. I guess it depends on the answer to the question. I have a mid-2012 Mac Pro with a Radeon HD 5770 1gb. It still runs better than new. If I were to upgrade my GPU, would I be able to install Mojave the "standard" way (i.e., download it from app store, install, and then boom, it's done) or would I still have to go through the same amount of BS that other people have had to go through just to upgrade their "unsupported" Macs that have more than enough horsepower to run the new OS? If so, what GPU should I be looking at? If not, Apple is killing me. I'm still having a hard time dealing with the fact that my perfectly good 2011 i7 MBP isn't getting the update. The Mac Pro came as a bigger surprise, I figured it'd be supported until at least 2020.
