Shrinking Available Disk Space
Since upgrading to macOS 10.15.6 my free disk space has been steadily shrinking.
Today I started out with 179GB free on my Mac's internal SSD.
I moved a 111.7 GB Scrivener file from my internal SSD to an external Drobo 5D3 and deleted it from the Mac's SSD
Then, I restarted the Mac. I now have only 157 GB free. This is the opposite of what should be happening. I've seen some other discussions relating to this on other Mac OS forums and the only common solution seems to be a clean install of Mac OS. I'm hoping that maybe someone here has perhaps another possible fix action. I've tried Cocktail to delete TimeMachine Snapshots, but since updating to 10.15.6 it will only thin, not delete.
Thanks for any ides/suggestions.
