After that when I finally managed to create the new Mojave installation (separate disk) the system picked up the card and woked fine out of the box. I took out the AMD HD 6770 and replaced it with the Nvidia GT730 and the Sierra installation identified it immediately (no Nvidia drivers required or anything) and reported the proper ID on the «About This Mac». So, I searched on the Internet and fount out that mine (GIGABYTE GT703 2GB silent), which I had bought for around 30-something euros about 2 years ago, was actually Kepler (GK208) compatible! Beware, other GT730s which are GK108 based are NOT metal compatible. Someone pointed out that the ones that are metal compatible are Kepler (GK208) based. The proble was that some guys claimed the GT730 worked out of the box and others that it didn’t work.

Looking around I found an note on a forum by some guy that Nvidia GT730 was metal compatible as Apple requires now for the graphic cards on Mojave and Catalina. I had to fix the ID numbers for the card (added the proper vendor:device ID) in the AMD5000Controller.kext and AMDRadeonX3000.kext and had to use the SwitchResX application to correct the constant display colour switching (between blue and green).Īnyway, when I decided it was time to upgrade to Mojave 10.14.6 I knew it would be a hassle to go through the same pain of making this card compatible on the new installation.

The card was AMD HD 6770 1GB (even though the system identified it as Radeon HD 5000 series), given to me by my son when he bought a better one for his gaming rig. I was using a nice but old AMD graphics card and it was working fine -almost, because it reported wrong ID- up until Sierra 10.12.6.
