Trying to do a manual backup of a 64Gb iPhone to an Mac Book Pro running Mountain Lion, iTunes stated that there wasn't enough disk space.

I deleted enough files so that Finder reports almost 95Gb free.

iTunes still states that there isn't enough space. On closer inspection, Disk Utility reports only about 20Gb free.

I've repaired disk permissions and verified and fixed the disk, booted in Recovery mode, but the reports are still the same.

I should have enough space, but clearly something is wrong here. Can someone please tell me what I can do to get the reporting correct and consistent?

If you have automatic Time Machine backups on:

Try to disable automatic Time Machine backup

Wait 5 minutes, Then try again

When you're done enable Time Machine again

  • You're a genius! That worked; any idea why Time Machine is causing this? Oct 16 '16 at 17:29

  • Finder and Get Info windows don't include them in their calculations. - that's poor design. Thanks ;O) Oct 17 '16 at 8:23
