I upgraded to Mojave and now Time Machine won't back up the disk
Hello Apple helpers,
I upgraded to Mojave and later I changed the name of the volume on my desktop to HD Mojave instead of HD High Sierra. Now when I try to use Time Machine it never finishes "Preparing Backup ....." and hangs for an hour. How can I change this to continue adding to my previous backups, or do I need to set up a new back up on the external hard drive I use for my backups?
