Hey guys, has anybody made the AMD Radeon R9 270 2048 MB work properly on the 10.13.4 ?
 
I've found the solution:

on the 10.13.4 you should add the 0x68111002 in these kexts:
AMD7000Controller.kext
AMDRadeonX4000.kext
AMDRadeonX4000HWServices.kext
then add the 0x68111002 in config plist in your clover, Fb Name - Futomaki and Vendor ID 0x68101002 (+ Inject ATI indeed).

Now acceleration works.

Also some info from another forum.. There are two options up to user's choice:
1. the 0x68111002 in AMD7000Controller.kext, в AMDRadeonX4000.kext + AMDRadeonX4000HWServices.kext + Lilu + WG;
2. Fake ID 0х68101002 + Lilu + WG.

number 2 is working for me.. but DVI port not working..
 
I have this same issue.

without acceleration, mostly working but I saw the same graph glitch as #12 post.

with acceleration, it boots into black screen but with a working mouse cursor.
I can even blind type password to login.

Clover Config
** DSDT -> FixDisplay=True
** Inject ATI = true
** Deinit = true
** FakeID = 0x68101002
** FBName = Futomaki

I have tried combinations of Deinit/FBname, but still the same. what else to try?


Boot args:
