macOS 12.3 Update Causes Problems for 5700/6800/6900 Graphics Cards

umm... not sure...

whomever done this:

<key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key>

                </data>
            </dict>

I suppose!

also XhciPortLimit needs to be disabled

As far as XHCIPortLimit goes, I have not been able to get my ports mapped as it always results in a USBMap.kext that causes the next boot after resetting NVRAM to hang with just the Apple logo and no progress bar. In regards to the two platform IDs, one is for my dGPU and the other is for my iGPU running headless.

Try this -- I use PlistEdit Pro. OCConfigurator gave me a lot of problems in the early versions. That sounds familiar, where I thought I made changes, and it didn't actually "take" after saving. I think sometimes it helps to rename the file, then after you get the final version, to rename it manually in the Finder. I don't know ... that's why I switched to the Plist editors. The code is more confusing at first but you get used to it....

Thanks, @tedyun I'll give it a try and let you know if I run into any issues.

Anyone else getting kernel panic after adding DeviceProperties with an RX 5700 XT?
The problem happens when the computer is waking up after sleeping.

Let's take a look! Feel free to post your EFI, config.plist (serial scrubbed) or the code that you used.

Hello!

Did anybody try render in Blender 3.1 with Cycles render engine using GPU?

I updated to MacOS 12.3 and added framebuffer injection to config.plist. Videoсard works well. But GPU rendering won't start (CPU renreding works). Reading Blender logs didn't help.

Hi tucoboy,

I just applied the framebuffer injection patch to your config.plist. If you look in the DeviceProperties section, there is a new entry with the PCIRoot path that you supplied. The patch that we've all been using is based on this information here:

macOS 12.3 Update Causes Problems for 5700/6800/6900 Graphics Cards

How's this... Looking at the above, we see your device-id is 7340 (shown under the Compatible key). If I were to add it to the device properties under the card's PCI root address (in the config.plist) it would be need to be shown as device-id 40730000. You will also need to add a...

seems like every other desktop background works for me without issues except for the stock Monterey one. I'll just switch background. Try deleting the graphics cache and then restarting, that worked for me.

I am using the 10900k with active iGPU and iMac20,2 and the glitches are gone after doing the W5700X config patch.

I'm not exactly sure how the technique works. This was based off the discovery that mattystonnie's old method of injecting the framebuffers could boost the performance of the Vegas and early Navis:

AMD Radeon Performance Enhanced SSDT

Introduction A couple of weeks ago I got my hands on a new Navi GPU, The Sapphire RX 5500 XT 4 GB, everything was working but the performance was not there, everyone said it is on pair with the good old RX 580. So I got my hands on the new macbook pro 16.1,mac pro 7.1, and looking into the...

The way I understand it is that these patches tell the macOS which drivers to load. I don't know how this is done under the hood. The framebuffer injections worked pre-Big Sur, but then after Big Sur, Apple changed the process so that the injections didn't work anymore. With this latest update, it was like the drivers were loading the incorrect drivers or something. They were loading a driver, just not the correct one. The framebuffer injection tells macOS to load the correct one.

I wish @mattystonnie or @CMMChris would pop in, but I haven't seen them around for a long time. They were the ones that wrote the SSDT or kext for Catalina, so they would understand.

Thank you for explaining all that to me. I really appreciate it. Now I just hope that whenever the next update comes around, that the injector (that you hooked me up with), doesn't need some other type of adjustment. Thanks again for your help!

I added an SSDT that I had here at the time of Catalina and it solved the problem.

SSDT-NAVI-RX5700XT.aml

Just FYI:: On my Z490 build with RX5700XT, this aml did not help with video performance at all.

Just to check: You checked, and modified as needed, the ACPI path in the SSDT, didn't you?

This v12.3 is a complete shambles with bricking Macs with new logic boards, display probs, dgpu egpu probs, external displays connected via USB-C probs

Besides the eGPU bugs. My system has been pretty stable. No issues at all after adding device property injection.
