Radeon Compatibility Guide - ATI/AMD Graphics Cards

Here I use 3 monitors connected to a Gigabyte Vega 56 OC Gaming 8GB, being 2x Dell UltraSharp U2419H and 1 LG 32 "4K UK550.
In Boot args I'm using agdpmod=pikera, but strangely when MacOS goes into Standby, and I try to go back to the system, using the mouse or keyboard, the screens are flashing several times and then I go back and I can enter the password to enter the system, other times it doesn't come back and I have to manually reset it.

Have you tried without pikera? That boot argument is for Navi RX 5xxx series.
 
The next challenge is to make Intel Wireless AC 9560 CNVi work on MacOS, both wifi and Bluetooth.
Use the search tool there has been progress on a thread here for that. I believe the Bluetooth can be fixed using an ACPI patch, but there is an Intel WiFi driver thread that seems to be working for some users.
 
Hi everyone.
On my first HxOsh setup, I managed my way through the first boot issues, plist and all. However, it seems I am stuck inside something that looks like a compatibility issue.

I have a
x570 Tomahawk, and a
RX570 installing
osx Catalina
and when the GUI initialises, my screen doesn't get rendered properly.

edit: I am in the usb installer step - so I didn't have a running and working config before.
Also: I (seemingly needed to) create my own SSDTs b/c the precompiled ones for AMD didn't seem to work either. I suspected this to be an x570 chipset issue. Also one recommended setting (settingvirtualmap) needed to be set on FALSE otherwise it wouldn't boot- idk if that has anything to do with the issue at hand, but nonetheless.

I use the
latest opencore 0.6, the
vanilla ryzen tutorial and
lilu+whatevergreen from today (Sept-01-2020).

All resources pointed out I didn't need to edit bootflags, framebuffers or kexts, since everything should be included by default e.g. macos providing support for my video card oob.

I tried switching through all ports on my card, but the picture always looks like this (attachment)

Any hints welcome - b/c now I am all out of options / inet research was fruitful previously - but no longer.
Regards
(edit reason: added infos - also also: crp, didnt see the catalina dt support forum, google brought me here. move if needed pls, thx.)

I tried to Install Catalina with my RX 580 on my PC after using UNIBeast without any modifying in Clover configurator and I would get a black screen while loading on the apple screen on my PC. I took out the Saphire 8gb nitro+ RX 580 and put in my old 5750 XFX and it boots and runs the installer and and gets to the desktop of Catalina! I tried so much I haven't slept in a week!!!! Can some one help me out please! I tried a lot and Im about to sell this card and get another one !
 
Here's a general question. What AMD cards are recommended right now, if I want to upgrade to Catalina? Currently unable to upgrade due to NVIDIA. It doesn't have to be amazing for gaming; I dual boot Windows for that.

I would be running the AMD card for Mac and NVIDIA card for Windows. Hopefully that wouldn't cause problems of its own.
 
Why is there no mention in this list of compatible cards of Radeon HD 6450 or HD 5450 .. They do work in some MacOS versions if memory serves

5600XT at low end and 5700XT on high end. Also if you can find used RX580s those are good too.

There's new RDNA 2 cards coming next month, so it's better to wait for that. I am personally going to get the 6990XT most likely and swap my Radeon VII into the loop.

You will need to move to Big Sur though when it's officially out.
