Time Machine Recovery
I was upgrading my iMac's hard drive to a SSD drive this weekend. I did a Time Machine backup of the computer that started as a Mojave OS but is now Big Sur. Time Machine said everything was good and so I swapped the harddrive.
When I attempted to recover from Time Machine everything looked good when I logged into the backup and attempted to recover. It then reported that there was NULL data to recover and the process stopped.
I needed to get the computer back online so I started the recovery of the OS(Mojave) and after a day of loading and updating back to Big Sur, I tried to reload the Time Machine backup.
So far, so good, it looks like Time Machine will not recover a newer instance of the OS when in recovery mode. If that is the case, I would like to know how I can upgrade/update the recovery boot OS to keep it current as the computer ages? I would much rather have a 1 1/2 recovery time, not a day and a half.
