I back up all the work from my MacBook Pro to an external hard drive. Like all things in my house, it stopped working - the backup that is. Every day an ominous warning appears on my desk top. You haven't backed up your data in 63 days! 64 days! 65 days....
I called Apple Care for help. The woman listened, asked me to again explain the problem, and then said she needed to reach out to a supervisor. About 10 minutes later she was back.
This was her troubleshooting suggestion: wipe out the computer hard drive and try again.
"I'm sorry, can you repeat that?"
"Let's just start you with a clean hard drive."
"You want me to wipe out my computer's hard drive?
"Why would I want to do that? Years of work! I just told you, I can't back up anything."
"That's all we can suggest from here."
Maybe I'll try the Genius Bar next.
