System takes up loads of HD space

Run this command in Terminal and give it a minute to complete, then post the results here. This will show all the base folders and space used by each to give us an idea what is going on.

Code:

sudo du -d 1 -x -c -g /

Also, sometimes what happens is the Spotlight index gets corrupted and this causes that storage readout to all wrong. If you run the command below in Terminal and give it a half hour or so to work... it will reindex Spotlight and often fix that storage readout.

Code:

sudo mdutil -E /

 

Yes... but you jumped the gun a bit... it is not done yet. Let is finish. You will see a total at the bottom when it is done.

 

I don't see anything really wrong there. Looks like most of the space is being used by your personal Users fodler there. Gran an app like OmniDisksweeper and use it to see what is taking up that user space.

Does 360GB sound about right for all your personal files and data?

 

I don't mean there... because that can be off due to the issue I mentioned earlier. I mean, just off the top of your head, does that sound about right for all your data?

Run Omni and it will give you a nice graphical layout of the biggest storage sections in your user account.

 

Give Omni a run and you will be able to see.

Or you can run this command to see what users folder space usage is. This is a little different from the last command with the ~ added in for users folders.

Code:

sudo du -d 1 -x -c -g ~/
