Apple - How can I free up some disk space?

You can try :

• Disk Inventory X (free one)

• DaisyDisk (paid one)

Omni Disk Sweeper by Omni Group is good at helping find the mountains of stuff.

I find that apps and the system folders generally don't take up that much space (everything being relative), that the real hogs are in the Documents, Music, and Movies folders of my user folder.

Two things...

1. If you are starting to run out of disk space deleting files isn't going to help much unless you have massive amounts of waste, eg Old systems from doing an archive and install OS update.Start thinking about getting a bigger hard drive or some extra drives.

2. In terminal type...

   du -hs *

This will list each directory with it's size. It will look smething like this...

3.6G    Desktop
3.9G    Development
 42G    Documents
1.6G    Downloads
4.5M    Dropbox

If anything looks unexpectedly large cd into the directory and run the command again. Rinse and repeat until you find what you are looking for.
