The best answer then is to start a new backup set, if possible. A range of problems have been reported by some users, typically that Time Machine refuses to make any new backups to an existing backup set. Many users have had no problems with their Time Machine backups following upgrading to Catalina. backupbundle can still be mounted using an older DiskImageMounter app in /System/Library/CoreServices, although whether you can use Time Machine to retrieve any of its contents remains unclear. Once they have been changed, they can no longer be accessed from any earlier version of macOS, at least not recognised as containing a Time Machine backup. backupbundle to reflect their being updated for 10.15. If you back up to a Time Capsule – or to another networked storage device – it appears that this change is reflected in the extension used by Time Machine backups, which change from being. Unfortunately, Apple doesn’t appear to document Time Machine for developers or advanced users, so that is all that I can find at present.

In one Help page, Apple points out that “if you create a backup on a Mac or partition with macOS Catalina, you can only use that backup on Mac computers or partitions with macOS Catalina.”Īdditionally, in this article: “If you upgraded to macOS Catalina on a Mac that uses a Time Capsule or other network storage device as the backup destination, your existing backups are also upgraded and can be used only on macOS Catalina.

I now formated the drive with OS Extended Journaled after having consulted various articles on the internet.
Unfortunately this was after I had erased the content of the TM drive.
I always had to force a restart with the front button on the Mac ProĪfter some test I found that I could get a "normal" restart from the computer if automatic back-ups was UN-checked I noticed that I had a problem when restarting the computer from the apple menu, it wouldn't quit altogether which was noticeable with the faint light on one of my two monitors.
