Time machine is not able to succeed a back up after Catalina upgrade
Time machine is not able to succeed a back up after Catalina upgrade.
Nothing change since the upgrade to Catalina and Time machine software has stopped working. Either Backup on a time machine capsule or on a compatible NAS, time machine is not able to make a backup.
On disks properties there are two sections, one as a Macintosh HD and one as a Macintosh HD Data.
I am looking forward for your valuable assistance.
