Spring is right around the corner, and I've had my Macbook Pro for about 6 months now. It's starting to feel dusty and cluttered. What is the best method of I guess organizing and cleaning up a Mac? Like on Windows, I'd clean up the registry, defragment the HDD, delete files/folders of programs that I uninstalled but still stayed, erase free memory, etc. What would be the equivalent to a royal washing on a Mac? Unrelated question: I have this file called sleepimage in /private/var/vm that's taking up 8GB. I'm sure it's an important file, but is there any way to decrease the file size?
