I’ve tried it a couple of times and it never seemed to download the newest release. Still haven’t managed the update, right now it won’t even let me start the install anymore.

I usually do a time machine backup and then copy all the files over to a separate hard drive as a double backup just in case. Simple restart and hold Cmd+R to boot to the recovery partition and then you can reinstall. One thing to note, I think you need to actually update to Big Sur first before doing this, as I think the recovery partition method only lets you reinstall the most recent version on your Mac. So you can install the Mac’s original OS, or the most recent Mac version (that you had installed). Once you’re done manually copy all the files back over. As 11 is such a big jump I’ve decided to do a clean install myself. Going to update first, then reformat and reinstall macOS 11. That is if the download ever works. Another option is to create a bootable usb with macOS 11 on it, I prefer the recovery partition method though.

Bit daunted about putting all the files back on it. Do you just put them all on to an external drive and move them over bit by bit? Obviously doing a Time Machine restore defeats the purpose.
