The Path I Follow

First of all, I couldn’t install Montere directly no matter what I did. Continuous reset or error. So I decided to install and use a clean Big sur. After a successful Big Sur installation, I manually made my ACPI settings, USB settings and all other settings one by one, and I was able to get everything working without any problems. I then downloaded and installed the Monterey update from System Preferences. installation completed without any problem and I was able to upgrade to monter. I’ve written the working and non-working features and hardware below.

Working Fearures

  • Graphics Card: Metal and Open GL support works fine. 3 x 3440 x 1440 Ultrawide displays are working smoothly. 2 displays are connected via Displayport and the other via HDMI. Sound goes smoothly to all screens through the video card.
  • USB : All USB ports are working fine. Type-C input is also fine. Thunderbolt works fine on my sound card.
  • Airport: I have been able to send to my tablet without any problems. Likewise, I can send files from the tablet to the computer without any problems.
  • Bluetooth : It works fine. All my bluetooth hardware is connected without any problem.
  • Sleep and Wake mode: It works fine.
  • iMessage, Facetime and Handoff: It works fine.
  • Playing DRM protected content: Apple TV works fine, Netflix works fine (via Safari) , Disney Plus works fine (via Safari)

Non- Working Features

Sidecar doesn’t work because I installed with iMacPro1,1 SMBIOS without iGPU to play DRM content. I made an installation on another hard drive with an active iGPU. Sidecar does not work there, but DRM content is not played. So as you can see, I have set up a separate Mac for work and everything works except the gpu and DRM there, and I set up a separate Monterey for entertainment. The one for fun also works with DRM but no sidecars.

I couldn’t load the EFI folder without attaching the file. It gave an error that the file size is too large. I uploaded google drive. you can download it from there. I hope it helps someone. I’ve been working all day for 4 days. Efi

The only issue I have is that the internal usb2 headers dont work with your usb kext. I have the same mb and cpu. Do you have any ideas why this would be?
