Radeon Compatibility Guide - ATI/AMD Graphics Cards

[michaelbp]

I just installed High Sierra (upgrade from Sierra). Got both monitors and USB ports working on High Sierra. with the new install, (& Gforce GTX 660Ti), the graphics are flaky. I purchassed and installed a Radeon RX 580 and only one monitor works (second monitor is plugged into a display port).
I'm having trouble determining which kext files are needed.
Do I need to remove all the Nvidia kext files for the RX580 to work?
How do I get the second monitor to work?

You appear to not have Lilu or WhateverGreen; is that right?
You appear to have an old Clover version; is that right?

 

[michaelbp]

Correct, i do not have Lilu or WhateverGreen.
I'm looking at the "iDiot's Guide to Lilu..." - looks like that install may solve many of my issues.
Clover version is not too old (don't have v-# just now). Clover displays gray Background when loading.

Suggest following:
Update Clover to vLatest.
Update to use WEG and Lilu.
Retest.
BEFORE YOU DO THIS: Make sure you have a BOOTABLE USB stick that WORKS, in case you need to revert.

thanks dclive,
please clarify a few things for me:
when I update clover does it retain the current kext files and commands?
- and so (assuming it retains old commands) will I still need to remove the old/previous nvidia kext files/commands (in config.plist and ../extensions)?
- do you recommend a clean install of Clover? that is completely remove my current config.plist?
- if i remove and replace .plist, is there a guide to do this? (brief summary of steps)

No. The Clover EFI and associated files distributed with Clover are updated.

- and so (assuming it retains old commands) will I still need to remove the old/previous nvidia kext files/commands (in config.plist and ../extensions)?

I wouldn't lose sleep over it, but yes, you should probably clean up the old nVidia stuff at some point.

- do you recommend a clean install of Clover? that is completely remove my current config.plist?

Heck no. I suggest doing what I wrote earlier.

- if i remove and replace .plist, is there a guide to do this? (brief summary of steps)

I wouldn't replace any of that. Just make the backup of the USB boot, test it, then do the three steps I listed.

I know it’s pretty much brand new but has anyone got an 5600XT up and running yet? I think I saw somewhere that it has the same PCI_ID as the 5700/XT so *should* work but I’m interested to have this confirmed.

10.15.3 beta (19D75a) includes support.

The first post is very outdated. Will it get updated?

Will adding Lilu and WEG via multibeast enable HEVC? I just installed the RX 560
