There was a similar discussion late last year and it looks like it's closed. The discussion ended with a post that this issue was fixed; only it has surfaced again. I maintain two time machine backups; one to a WD drive, connected via my home network, and the other to a Lacie portable drive, which is disconnected except to do a backup. The time machine backups to my WD drive work fine. Starting yesterday, I'm now getting the following error when I try to backup to my Lacie drive:
"An unauthorized app attempted to access your backups. App: /System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd
We blocked the app to prevent it from altering the content of your backups."
What was the previous fix, and is anyone else experiencing this again?
