Hey again! Thanks for that info!
Finished backups are usually much larger than that, what was the capacity of the phone, or better, how much storage was being used on the phone at the time of the backup?
I believe it was after Catalina, (Maybe Mojave), that iTunes/Music backups changed, to just overwrite the same backup file saving HD space on your Mac, wonder if that’s related, but yeah, they’re typically much larger than that, so sounds as if incomplete.
Also 20gb free on your Mac isn’t a whole lot when comparing the size of a normal iOS backup, so that may also be a factor.
Also in that “Get Info” window, does the “Date Created” and “Date Modified” match the dates of the backups you’re looking for? Or are the older?
But I’m also wondering if the permissions are set correctly, also in that same Get Info window, on the bottom, does it show your current Mac user name? And does it show “Read and Write” to the right of it? (I’d also check that for then parent folder “Backups”.
You can repair the permissions of your entire user folder also if you need to, but other than accessing these backups, there’s no problems with any other apps?
Another possible step is just reinstalling Catalina itself, in case it’s just an OS issue, only hesitation about that is the size of the backups, if incomplete then that still wouldn’t work, but I’ve been suprized before.
Also, have you by chance started the restore from iTunes backup from the iPhone itself during the initial startup selecting “Restore from iTunes backup”? Or was the phone already set up and you’re just initiating it from Finder?
Sorry, my mind wanders, Hope it works out, nobody wants to lose their personal data, let me know what you find!
