Thanks
So I have created the workable clone on an external drive as backup and then a second as a working copy to test upgrading to Sonoma. Is it better to put a new version of Opencore on a USB key and select this in BIOS then boot the clone drive to test? Or just try and upgrade Opencore on the test clone? I am a bit unsure how to do the USB key route? I assume I need to get Opencore and all the kexts etc upgraded first before going to Sonoma?I always do it this way. An external SSD with a clone and an USB key with updated boot loader, in your case, OpenCore. Then, I do the update on the working clone. If it fails for whatever reason, you can fall back with a working computer.
This sounds like an option. I was planning to test the upgrade on the external test drive, then do the same upgrade process on the main machine.In case of success (for me, a couple of weeks running fine on the externals, MacOS and boot loader), you just have to CCC your external to the main (still having another backup somewhere, fruit cake happens) and dump the USB EFI to your main drive.
Only once I didn’t followed this procedure (my XPS in my signature) as I didn’t tested drive long enough (Ventura) and wiped my CCC backup once I thought that everything was fine! I had to rebuild my Big Sur drive from scratch (one day of labour)… The positive thing, at least, is that Big Sur was a clean install instead of my usual update procedure .
