Trashing files didn't recover space
I bit of a mystery ... any ideas where to dig around trashing files to find the culprit before I get nasty with it with an Erase / Restore?
iMac 2017
Mojave 10.14.6 (all updates ran, well maintained machine)
NOTICED MY ORIGINAL APPLE 1TB SSD had only about 60GB available
I trashed and emptied over 100GB off my desktop
but the available space remained about 60GB
I tried everything I know and all were clean
PRAM zap
unplugging it from power for hours
Boot Safe Mode
ran cocktail 12.5 Mojave Edition
ran Disk Utility
left it run (not sleep) over nite
opened Storage in About this Mac (see clues below)
CLUES:
Storage shows System at 447GB, but Info on my root system folder shows 9gb (which is normal compared to my other Mojave/FCPX machine)
PS: Okay, I checked my other machine - Storage on it shows over 300GB, System Info 9GB running similar apps
I have a large FCPX project going and haven't deleted my render files, but they don't explain WHY deleting over 100GB of files did not reduce my available space - which is my first concern -
