@yabusa,

After a little experimentation on my Z390 Designare with two AMD GPUs (RX580 in slot 1 and RX 5700 XT in slot 2), I was able to disable the RX 5700 XT (slot 2) with the attached SSDT.

Filename: SSDT-Disable-AMD-GPU-Slot-2.aml

Please give this a try.

CAUTION: Please monitor backplate temperature of the 'disabled' GPU with a temperature probe or thermal imaging probe. The card may remain powered although a driver won't attach to it. Periodically check to see if the disabled GPU's fans spin up to maintain a safe temperature.

Slot 1 and slot 2 versions of this SSDT are also posted here:
Here are some other things I've noticed

The second GPU is showing as built-in instead of slot 2

I gave the file a shot, but still no luck
My steps were:
- Add the .aml file to the ACPI folder
- Open config.plist with propertree
- Cmd + R to OC snapshot
- Saved and restarted

I found something interesting in hackindrom. The WX was listed twice
Not to start a religious war, but we should not use ProperTree and especially not use its Snapshot feature. There's no reason to use that type of app for most purposes when OpenCore Configurator is available. Those plist screenshots take quite some time to read.

Let's use OpenCore Configurator and add the SSDT to its ACPI section.

Having said that, it seems there is a difference in "attachment points" between the RX 500 series and its successors. The old RX 500 series attaches directly to PEG1.PEGP, but it renames PEGP to GFX1. The newer GPUs attach to PEG1.PEGP.<bridge>.GFX1.

Please try the latest version attached here. File name: SSDT-Designare-Z390-Disable-RX500-Slot-2.aml

Not at all! I didn't know any better. I ended up with Propertree by following the dortania installation guide
The OpenCore Configurator you suggested is MUCH more user-friendly and shows up automatically.
I absolutely hated the screenshot thing with Propertree. Just deleted it from my system :p
I'm glad you pointed that out brother! You got my rig back to perfect set up
I appreciate you a lot for your time and effort ❤️
You're amazing

Does this (and screenshot of Displays) mean that the latest SSDT succeeded in disabling the RX580 in slot 2? :)

The screenshot indicates that Table DMAR could not be dropped.
  • Which version of BIOS is installed?
  • Please post screenshot of OpenCore Configurator --> ACPI --> Delete as shown:

Greetings! I tracked it down. I got the same error with my backup recovery drive... I had saved a copy of BIOS settings and restored that. Don't know what BIOS setting I'd missed but all is well!

... in particular for Intel BT/WiFi and they work just as great for hackintosh. Check out the OpenIntelWireless Github at https://github.com/OpenIntelWireless and in particular, itlwm (for WiFi), the Heliport app (for older macOS builds like Catalina which also needs itlwm.kext to work) and IntelBluetoothFirmware. Both kexts work superbly on macOS for Intel based cards.

...
Just keep in mind that most macOS Continuity features will not work with Intel WiFi/BT.

Hi Casey, I'Ve used your amazing CC Cloner mini tutorial to clone a bootable version of my Big Sur drive. Once after I did a new install... Used the free version for that. However, I already have a paid version of Super Duper. How would we go along with Super Duper?

I'm on OC 0.8.3, BTW.

@grugattony I just went through this same process. Here is what Casey provided me:
Step 11 in the guide below contains the very latest backup procedure:

Alas I've not used SuperDuper, but I would check if it has the same "Legacy Bootable Backup" option as CCC. We can also search the SuperDuper help document or user manual for instructions on making a bootable backup. To clone the EFI folder, we can always manually mount source and destination partitions, then manually copy the EFI folder.
