I am stuck on ‘preparing backup’. I have tried to cancel the inProgress folder in the backups but still Time Machine doesn't work. Time Machine is just stuck for hours and I do not see any progress at all in the backup. The hard drive for the backup has a lot of free space.

I have tried all the potential solutions given in Time Machine stuck on "Preparing Backup" but the backup is still unable to proceed.

MacBook Air (13-inch, Mid 2013), High Sierra 10.13.4.

  • @grg I have updated my question. This question is not a duplicate because it regards high sierra, and it doesn't have an answer, because none of the receipts given work for me

    The macOS version doesn't matter, the preparing backup stage does take many many hours for a large backup. What does tmutil status say about the backup?

    What @grg said is true. Just to put it in perspective, it took 5-6 hours to prepare a 30GB backup on a MBP 2011. The actual backup took max an hour. Jun 10, 2018 at 16:38
