I keep getting a message from time machine: "Time Machine couldn't back up to "My Passport for Mac".
This WD hard drive is supposed to be linked to Time Machine without reformatting. what can I do?
MacBook Pro 15", macOS 10.14
Is this a new drive? If so, then you need to use Disk Utility to first erase the drive as GUID partition and MacOS Extended (Journaled) before TM can use it for a backup drive.
Or has this drive already been used on this computer as a TM backup and is suddenly not working?
