Diskspace Headscratcher (Two Different Capacities Reported)...

[spetznatz]

Hi All,

I was checking the disk space on the Internal SSD in my Mac Mini (Late 2012, High Sierra 10.13.6) and found I had hundreds of GBs in my Downloads folder, so Trashed them, then emptied Trash. SSD (512 GB) is now reporting ~200 GB Free.

I created an APFS container to do a test install of Catalina and tried to install Catalina to it. This morning I get a message 'Catalina could not be installed because there is not enough disk space'. Check my disk, and it's showing 480.94 GB used with only 28.1 GB spare. Did a disk sweep, which shows about 310 GB on the disk – what I would expect. But the Finder is reporting 480.94 / 28.1 GB. I've emptied the trash and restarted, always with the same results. If I try to transfer more than 28.1 GB, I get a 'Not enough disk space warning.

Any ideas?

TIA,

Tim

Maybe you have some invisible local time machine backups hiding somewhere...Yikes
Try a terminal command: sudo tmutil listlocalsnapshots /
What did you get? You can delete those files one by one using: tmutil deletelocalsnapshots 2017-09-27-005259
where the last "2017-09-27-005259" should substituted with the similar results from your disk/
then after they are all gone:
sudo tmutil thinLocalSnapshots / 10000000000 4
That 10000000000 there is how much you want to thin in bytes (so about 9GB).
Was that any help?
