Hi Weaselboy, I have a strange problem with my Mac too. I have a 250gb drive, but the omni sweeper only shows 88 and when i run (sudo du -d 1 -x -c -g ~/), it shows I only have 63gb in total. I tried finding if there are any other untitled drives etc but there is only one drive shown in terminal. I have been deleting big files in my drive, but everytime I delete them, it would be added on to the "system", leaving almost the same amount of Free Space. I have checked and time machine is not turned on and there is no image of any time machine backup in terminal as well. The "system" now currently sits at 214GB. Possible to assist pls? Thanks.
I am running the spotlight reg rebuild at the moment.
