Hi all, I'm running Mavericks and I'm really happy with it so far. I've only been on a Mac for 18months now so I'm still learning after using Windows for so long. In Windows I always ran defrag, check disk etc once a week. I've got no problems in OSX Mavericks, but I just wanted to know what I could do to help keep OSX running fast and reliably. In other words, I'm wanting to prevent problems before they happen. I'm still trying to learn the Terminal. Is there anything in the Terminal I can do? Thank you for any help!
