I simply bought a brand new MacBook Air (2020) and efficiently migrated my outdated system to the brand new system by way of “Migration Assistant.” The outdated machine and new machine are just about one-to-one the identical from a major admin consumer identify and fundamental arduous disk identify. No different customers on the machine.
Once I connected my good outdated Time Machine disk, that I’ve been sustaining since September 2019, I used to be requested if I wished to merge backups from my outdated machine with new backups of my new machine. Click on sure and all appears superb.
Now if I “Enter Time Machine” (by way of the menu bar) all seems strong and I can easily return to anyplace between September 2019 and now.
However I observed that if I manually look on my Time Machine drive on the directories for latest backups — as in the previous couple of days since this migration occurred — I’m seeing time machine backups for my system arduous drive and restoration partition named “Main” (present machine) and “Main 1” (outdated machine). Screenshot beneath.
Is that this regular? I assume I can ignore it and as Time Machine robotically cleans by the backups, these remnants with go away?
