Filesystem full System Data at 950GB

My M1 MacBook Pro is the household backup server. It has a batch of spinning disks attached to it.

From time to time it makes me regret running MacOS. Today is one of those days. I’ve rebooted the machine several times today and forced Spotlight to reindex once.

The SSD is 1TB, the file system reports that there is ~2GB free with another 70MB purgeable.

Looking from the root of the harddrive none of /Applications /Library /Users or /System has more than handful of GBs.

I really wish this thing was set and forget.

IMO, you need a minimum of 10% free space on your internal drive for normal operations. YMMV

Agreed - however this is a backup computer only. This “used” space is phantom. I can’t find it.

What happens if you try make a large file? E.g. mkfile 10g in Terminal.
