Hi,

Hi,

First thanks for your help, but there is still one of which EFI should I download that would be compatible with my hardware?

I also have a M93p, but equipped with a Core i5-4570T (same CPU generation, lower grade). I tried the following EFI folders, after I put the Olarila Big Sur 11.6.8 pre-made image on a 32 GB USB stick.

• OpenCore Notebook Haswell : after a long console display, gets stuck to a black screen
• OpenCore Desktop Haswell : kernel panic after AppleAHCIDiskDriver and AppleSMC panicked
• Also tried two EFI folders found on Github, one of them crashed, the other shows the Apple logo and a progress bar, and hangs at about 25 %. Added here for completeness.

The link in Maldon reply of May 3rd 2021 leads now to a 404 error.

use Haswell folder with -igfxvesa

• Desktop or Notebook?
• And where do I put the -igfxvesa option?

Thanks

Update: I used Notebook Haswell and I added the -igfxvesa option in config.plist (watched the first minute of

 to locate where to add). Big Sur installer went fine. Then, using Terminal from the installer USB stick, I copied the EFI directory from the EFI partition of the stick to the EFI partition of the SSD. When I reboot, I get a kernel panic and system reboots immediately, not letting me to read what happened.

Status update

Status update that is very late: I succeeded to install and use Big Sur on the start of August 2022, but I don't remember what I did to solve the kernel panic. On August 3, I asked a question about graphics acceleration that was not working, tried many things until I find I was editing a config.plist file that was not actually read by OpenCore. After mounting the correct partition with ESP Mounter Pro, and editing the correct config.plist, I was able to get graphics acceleration.
