Yep, I’m slowly getting used to the open-core, I set the download to 1 second, I thought this window could be completely removed, but no))) I changed the version of the macbook, as in my opinion. The processor is more suitable for 15.2. A couple of reboots and the system began to heat up and slow down less, but it's still slower than Catalina on a clover ... although I think I need to test and fine-tune the system for a couple of days. btw i added "-igfxblr to boot-args" and boot is now normal without black screen and 5 minute wait. If I throw off the EFI with my changes, can you tell me what else can be changed there exactly for my laptop configuration?
