My Macbook Pro says most of its hard drive space is taken up, but I don't have a lot of stuff on there. I think there might be info from old installs of the OS floating around on there somewhere. How can I find out and/or get rid of them?

    I assume you've emptied your trash? Just have to ask. Here's the thing about OLD installed of OS X. If you have them, there is a good chance you can't get rid of them without screwing up your current OS install. If you do have old system installs they should be in your Macintosh HD\OLD SYSTEMS if I remember correctly. It's something like that and VERY obvious. All the "reinstall over OS" does is makes your current system folder into that and makes a new system folder. So if you don't have anything in the root popping out at you then it's probably not old system installs. Plus they are usually 4-8gb each and I can't imagine you've rewritten your OS so many times for this to be the case. Here are a few things to check whats eating your space:

    1. Check to see if you have any OTHER USER accounts on your system. If so, see how much space they are using.

    2. Check your iTunes. If you download a lot of movies and tv shows they add up very quickly.

    3. Did you empty your trash?

    Those are the 3 to check without getting deep into scary land with cache files and tmp files. Really if you still cannot see what's eating the space, backup your user, reformat and reinstall your user and applications from scratch. I believe Hicks said in Aliens "Nuke it from orbit... only way to be sure."
