Hello,

I switched my desktop motherboard to upgrade my haswell, the old EFI didn't work, so I tried to redo it. I followed this tutorial

OC 0.9.1 (debug mode)
Motherboard: Machinist B85m-PRO (from China, AliExpress)
Processor: Intel Core i7 4790
Disk: NVMe m.2 (with macOS Big Sur already installed)
My old motherboard: Gigabyte (everything worked wonderfully)

I've already tried to boot via NVMe or an SSD (SATA), both have the same problem, as can be seen in the attached image. My EFI folder is attached too.

Could you help me to solve this problem?
Thank you very much!
j.

Never heard of Machinist motherboard and it's not on recommended list for macOS compatibility. I even Googled it and there's not much info on that motherboard for hackintoshing.
