Hey,
I used “Patched sur” (you can find it on page 1 of this forum. If your looking to upgrade to Mac OS 11, try that. It was a simple install for me, no need to drag and drop things into terminal, that confuses me as well 😅, all you need is a usb and some time. But with this one, you need to get to Catalina then to Big Sur. From Catalina and lower will not work. It took a few hours for me on a ssd, it needs to install a 12 gig file (installer) then make the usb bootable, and the patched, then boot from the efi usb one (should power off, that’s good.) then hold option again and then choose the normal one, should have a install Big Sur or something, I can’t remember. Then continue as you would with a supported Mac. And you should be good to go afterward. If your WiFi and others doesn’t work, go to applications and then find the patched sur file, then there should be an option for the extra patches for WiFi and all that stuff. Install that and you are now running Big Sur, enjoy 😉

but does that still work for 11.2? I thought there is an issue with no longer having a full installer available or something.
