Hey guys, so it's 11:40 PM. I had a bit of a ride tonight because this motherboard is such a pain.
I was able to pretty much stick with my Big Sur settings to install Monterey.
One thing though, my onboard Ethernet is no longer recognized in Monterey. Unfortunately, this is not acceptable for some of you, but I went ahead and bought a USB-C PCIE and a USB-C -> Ethernet adapter. USB-C seems to be very native to Mac so it works great as a PCIE.
Sound, mouse, everything works great.
Sapphire RX 580 8GB detected - shows up in my About Mac. Tested a 4K sample on Youtube, looks great.
I would say success!
Make sure you get the latest of all the kexts in Open Core and definitely upgrade to 0.7.4 as mentioned above.
If anyone figures out the Ethernet issue let me know. The latest Realtek Kext did not work. It worked on first boot, after that it just switched on/off every few seconds and then after a few more reboots the Ethernet interface went away altogether. So weird!
Good luck hackintoshers, and see you for OSX 13!
If someone here needs me to post my EFI please let me know.
