deeveedee Posted July 10, 2025 Share Posted July 10, 2025 I'm not familiar with your motherboard, but I did google it and found at least one github repo with the Open Core solution for it. After searching, you may find that someone has already done most of the work for you.

deeveedee Posted July 11, 2025 Share Posted July 11, 2025 @Seb1r1an It's normally helpful in cases like this to have your EFI for review. It's your call about how much info you want to provide in order to make it easier for others to help you. Also, correct me if I'm wrong, but your 'f' CPU has no iGPU. Have you booted a previous version of macOS with your EFI?
