Hi

First post here, I'm quite noob trying to making work an AMD RX580 on macOS Catalina (after failing in a High Sierra try)

I have installed WhateverGreen and Lilu Kexts, tried fake-ID, loaded 1002_6fdf.rom in EFI/CLOVER/ROM through "Load vbios", and all other possibilities I have found in this forum, but nothing works for me.

The nearest I've got is to get the card listed in System Info as “Chipset Model: ATI Radeon HD 4330M series / VRAM (Total):7 MB”.

Any idea about what can I do? Any help appreciated


PS: I post a new thread because the ones I find for RX580 are marked as “Not open for further replies.” Please move to the correct place if it's the case

A standard RX 580 has native support (no need for Fake IDs or ROMs etc).
7mb VRAM is usually an indication that the graphics driver has not loaded.

What make/model is your RX 580 ?
Check in Windows or Linux what the Device ID is.
 
Hi

Thanks for the reply

My RX 580 isn't working OOB

On LINUX-sysinfo i get this:
Device-1: AMD Polaris 20 XL [Radeon RX 580 2048SP] chip-ID: 1002:6fdf class-ID: 0300

I also attach the windows GPU-Z screenshot

your zipped EFI would also help
 
Here goes my zipped EFI folder

I think it will have quite a few bugs after a lot of testing, sorry for this

Thanks for the interest

maybe set:

Code:
<key>ATI</key>
            <string>0x067DF</string>
to:
Code:
<key>ATI</key>
            <string>0x0</string>

probably do not need:

Code:
<key>EDID</key>
        <dict>
            <key>Inject</key>
            <true/>
            <key>ProductID</key>
            <string>0x6FDF</string>
            <key>VendorID</key>
            <string>1022</string>
        </dict>

should both be set to false:

Code:
<key>Inject</key>
        <dict>
            <key>ATI</key>
            <true/>
            <key>Intel</key>
            <true/>

probably do not need:
AMD9500Controller.kext
AMDFramebuffer.kext
 
I have tried the changes that Feartech suggests (also rebuild kext caches), and the card still shows up as “ATI Radeon HD 4330M series”

I don't know if it's important, I forgot to mention that my system definition is iMac14,2

also you do not need the rom files either

I've tried removig the rom files and with LoadVBios <true/> and <false/> and it didn't work for me either :(

you have to upload your updated config.plist if you have made changes

also reset nvram
