Time Machine unmounting itself repeatedly.
Hi all -- I have been using Time Machine with a Seagate external drive for the backups. Over the past year, however, I keep getting the message that I have not ejected the disc properly, and the icon disappears from the desktop. I've tried four different brand new external hard drives, different cables, different ports, nothing stops the issue from happening. I saw that someone else had this problem on here, but it wouldn't let me post on that thread. Has anyone heard of this, or come up with a solution? I'm using Big Sur on a MacBook Pro with plenty of storage left. (Strangely, About This Mac isn't showing the OS version in use. Weird!)
Thanks so much for your help!
