Replace the SSDT with this one. Also the Audio, Font, Image, and Label folders need to go inside 'Resources'.



The SSDT method is a lot easier.

To flash the firmware you can either use a CH341A programmer

or a Raspberry Pi

Then firmware:

Then edit DROM:




I'm not seeing your PCI card in your ioreg. Looks like you may need to reseat the card

I too am interested in this topic. I got both a Raspberry and an eprom programmer (I have to check the output with a tester). I have seen that you have used the firmware that in the repository is indicated for the Gigabyte Z490 Vision D motherboard ...

1. You may need to use a thunderbolt 2 dock then a thunderbolt 1 adapter but I'm not sure since I have no thunderbolt 1 or 2 devices. Would check Caseys thread on that.
2. If it's not showing up in windows it's most likely dead. I would suggest trying to RMA it.
3. It was originally used since vega drivers were not good in macOS. Later versions fixed the fan curve. If you want to mess with fan curves and overclock you can still use it but it'll have to be adapted since your graphics card is in another slot than what kgp had.
I am having lots of random reboots, maybe kernel panics, where the computer reboots and I am given a message on a black screen saying that the computer had to reboot and then another message in macOS saying that there was an error and that macOS had to be restarted. It usually will not stay booted for more than 1 hour without rebooting. Usually it is idle when it reboots, but not always. I do not think it is going to sleep, but I can't seem to find where I can disable sleep. Here are files that might help diagnose (I removed the "Resources" folder from the EFI). Thanks for any assistance you can offer!!

Having lots of random reboots really sounds like a RAM problem. Have you run memtest?

A probably stupid question: on my sage / 10g mobo there are 4 power connectors: 1 x 24 pin, 2 x 8 pin and 1 x 6 pin. The manual would seem to say to connect the 24 pin plug and: 1) or only 1 x 8 pin 2) or 1 x 8 pin + the 6 pin connector. My psu only comes with 1 x 24-pin cable and 2 X 8-pin cables. I found conflicting versions of what to do. Can you help me please?

Memtest...is that an ASUS motherboard function/feature? Yes, I think I did run it already, early on, but I’ll try it again. If Memtest is something else, let me know.

I would connect the 1 x 24 pin and 2 x 8 pin. The 6 pin above the 1st slot is for extra power for the pcie slots.

No not a motherboard feature, but a tool to help diagnose memory problems. See https://www.memtest86.com

I attached a version you can load directly from Opencore.
Unzip and move the whole folder under EFI/OC/Tools. Then create an item in your config.plist under Root/Misc/Tools as per the screenshot.

When you are at Opencore picker, pressing spacebar will show auxiliary boot options where you can select memtest. Just let memtest run on default settings. IIRC it will run four full rounds of tests on default which will take a lot of time so maybe you can let it run during the night for example. If it found any errors, either you need to relax your memory settings or remove half of your memory sticks and then run the test again. Then, for example if you remove 2 out of 4 RAM sticks and memtest no longer finds any errors are you can remove the remaining 2 sticks and reinstall 1 of the sticks you removed in the first place and test with just that to narrow down. It may be you have to test each RAM stick one at a time.

Ended up getting this card from OSXWIFI , it works great but I can't seem to turn off bluetooth at all, the function is simply greyed out, not that i need it turned off just though it was odd.

Maybe because its an official apple card stuck in an adapter?

this worked out nice though so I don't loose Wifi 6 functionality under windows

Have you made a USB mapping? or disabled the onboard BT?

Well, I guessed out that MemTest was the MemTest86 tool before I saw your post here. I ended up running it from a USB stick yesterday and it finished all 4 passes with 0 errors. It took more than 8 hours. I assume that is the same test that would run from the open core folder you sent me, right?

So no memory errors, so I'm guessing that that might rule out memory as being the source of my reboots, right? If so, is there anywhere else to look to try to diagnose why MacOS is unstable this way?
