Hi all,
I have a 4,1 cMP with a MSI Gaming RX 480 8GB.
It's been running perfectly under Sierra until recently. I upgraded to HS and all was well.
I then upgraded to Mojave and now my machine won't boot.
If I swap in an older Mac GPU, it boots. If I boot up with both cards, under the system report it shows the RX 480 as 'display' - no kexts are being loaded.
I was under the impression that the RX 480 was a supported card? I tried editing info.plist in the AMDRadeonX4000.kext folder to include the 67DF identification and ran kext utility to repair permissions, but still nothing.
Does anyone have any ideas? I've tried with both a DP monitor and an older one via DVI.
Thanks in advance.
