macos 10.15.6 breaks Time Machine backups
I recently installed the macos catalina 10.15.6 update on my iMac. Since then, Time Machine cannot backup to my NAS, and produces the error "Time Machine could not create a local snapshot to back up from."
I also tried adding a new local drive thinking it may be a Time Machine issue backing up to NAS. When attempting a backup to the new local hard drive, Time Machine produces the same error, "Time Machine could not create a local snapshot to back up from."
Plenty of free space on my Mac hard drive, and even tried the sudo tmutil listlocalsnapshots / and then sudo tmutil deletelocalsnapshots and then tried running Time Machine backup again and still same error.
I contacted Apple Support and they said they are aware of the issue and it's been reported by numerous users. So in the interim, I have no way to perform a Time Machine backup while Apple figures out the fix.
I also have a MacBook Pro with macos mojave 10.14.6 and Time Machine backups are not an issue and work fine.
