I have a MacBook Pro (17-inch, Mid 2010) Snow Leopard 10.6.8 with 4 GB of ram. I pressed the Erase Free Space button in Disk Utility thinking it would be good for my mac.... Instead I realized too late that it was eating up ALL my HD space. I panicked when it was down to the last 2 GB and force quit Disk Utility (which from what I understand isn't good to do in that process) After I freed up some space by deleting files and now my HD is up to about 20 GB. My computer is actually running very smoothly right now despite how much space I have left on it. I did some googling and I've tried using the terminal to find and delete the files Disk Utility created. I put in the command sudo rm -f /var/root/Library/Cashes/TemporaryItems/* Then the terminal wanted me to put in my admin password, I tried too type it in, but the curser wasn't moving. I pressed the keys of my password anyway and pressed enter. I'm not sure if it did anything. I quit terminal and brought it up again. The curser was all the way to left with no other text. I tried entering in the same command and pressing enter and the curser just when to the next line, and nothing seemed to happen. What is the safest way I can fix this????
