I am currently at OS 10.15.7, not because I want to be. I have repeatedly failed to install Big Sur. I believe there is something wrong in the boot sequence on my harddrive, since I need to boot, os 10.15.7, from my installer USB. It will not boot directly from my harddrive. Both the usb and the harddrive are on the same version of clover,5119. any useful help is greatly appreciated.below is my system particulars

For Big Sur fresh installation or upgrade, minimum boot loader requirement is Clover r5123 or OpenCore 0.61.

I first tried the few weeks ago with R5128, and most recently r5130. There seems to be some trouble switching boot loaders from r5119 (Catalina) and r5130 (Big Sur) during the update process. Is there a bootloader than works with both

OpenCore works with both....I suggest you try with that instead of clover.

I have poked at Open Core a bit, I guess I will need to learn it properly. Any suggestion for tutorials?

Very detailed guide. If you concentrate and read carefully, you should be able to work it out.

If I did then anybody can...:lol:
