I’ve ran into this problem where my external Thunderbolt volume, which is formatted with encrypted APFS is not letting me free up any space, regardless of what I do.
When I first noticed, I manually went in and moved about 100GB from the drive in question to another location in order to free up space. However, when I went to save new stuff to the volume, it once again complained it was out of space.
This is what’s being reported in DaisyDisk:
This is what
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on /dev/disk3s1 1.8Ti 1.8Ti 39Mi 100% 2603571 19530493869 0% /Volumes/2bigRAID
If I run
du on the disk, it reports a total of
880G (the disk is 2TB).
I’ve tried the following:
- Used the CleanMyMac “Clean purgeable space” feature
- Rebooted in recovery mode and ran First Aid on the disk
- Made sure trashes are empty
All to no avail. I can’t add any new files to this disk. I’m borderline considering making a copy of everything to another drive, re-formatting this one and then moving things back. But, it’s an SSD and I’d rather avoid the unnecessary write cycles if there’s something else I haven’t considered.
