I'm trying to restore my computer to a previous backup of my Mac HD. However, when I try, I see an error notice telling me that I cannot, since this file is not able to be deleted:


How do I restore to this backup from last week, considering that I can't delete the above folder, or resultantly, another version of Mac HD ?

What I've done:

Enter Time Machine > scroll through to appropriate backup > hit "restore" button > You can erase volume “Macintosh HD” and replace it with the restored volume or cancel to stop the restore. > receive error notice related to the above.

  • Can I suggest you edit your question to describe the steps you're currently taking to restore from Time Machine?

My assumption from how your question is worded is that you're trying to recover an entire HD, not just a single file, folder etc.

Instead, to do a full restore of your Mac you need to boot into macOS Recovery and use the Restore from Time Machine Backup utility.

  • Really? If there's something unclear on that page you should let Apple know. You'll see at bottom left a Helpful? section with Yes | No buttons and clicking on No provides a box for you to provide feedback. Re your question, how are things now? Are you closer to your goal?

  • Could you edit the answer, so that I can remove my downvote ? I put my feedback on the first link site and I feel that my -1 was unjustified.

  • I've just made an initial edit of my answer, however, if there's something specific you wanted me to add/remove/clarify please let me know. :)
