Just curious, is it technically feasible to have OmniDiskSweeper calculate other user accounts if you are an admin user or can gain admin user privileges? To my mind, the greatest limitation of ODS at the moment is that you have to run it in every single user account to be able to get a complete picture of what space is being used.

You can make OmniDiskSweeper calculate other accounts if you authenticate and launch it through the Terminal. In a terminal window, type :

sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

and enter your admin password when asked for.

Of course, as OmniDiskSweeper is now launched as root, you should be careful with that "Delete" button...

Unfortunately, that command doesn't work for me because I do not run my account as an admin. I forget how you switch to a sudoer in Terminal to be able to use it...

To switch to an admin account, use

su <admin user>

Doh, I knew it was something simple... thanks Len.
