I have replaced GTX660 with RX580 (PowerColor Red Devil), and it boots up as swiftly and smoothly as usual. To make RX580 work, I have modified Clover like below:Glad to have found this thread dedicated mostly towards the 660. I've updated to 10.13.2 Developer Beta 3 and the problem remains. I hope Apple is looking into a fix...
For those of you who own the RX 560 (XFX-AMD Radeon or PowerColor Red Dragon), can you tell me if your Mac boots up with the Apple logo? Thx.

Thanks for the info, leonhong. Really appreciate it... So regardless of the Mac one would own, the RX580 or even the 560 will also work, correct? Also, assuming Apple fixes the graphics bug with the 660, will the modified info work as well?
