Tried Everything. Can't remove "invisible" purgeable space that is maxing out my computer.
My computer has about 50% purgeable space. I've spent the last 2 days reading all the things I should do and did them: (emptied trash, removed all connections to my computer, repaired in Disc Utility, reinstalled OS, repaired disc utility in recovery mode, used different brands of cleaning software, and more etc, ).
I believe my problem is related to offline syncing programs (sync.com and backblaze) since it started when I tried to upload a large file to a vault. But I've already stopped that process and removed all files and software in offline storage connections (and my computer it is not connected to any phone). Any more ideas? I keep getting warning messages my computer is almost full.
