It's important to know how to clean your disk when using Apple's Mac OS X, since your computer can get “jammed up” in certain spots that may cause it to freeze if not taken care of. You can do this manually, or use a free Apple utility for Mac OS X to simplify the process.
Your Mac stores a lot of log files, most of which you never need to look at. Open the Console app (found in /Applications/Utilities), and you'll see a list in the sidebar of the Console Messages window. You can safely delete these without affecting your Mac, and since some of the files are very large, this can free up a lot of space. For example, you might find lots of system.log files on your disk. The one named system.log is the current file, but others with a .bz2 suffix are archive files.
If you don't care too much about managing your iTunes library, it's likely that you have duplicates. There is a built-in feature in iTunes to find them, so check if you accidentally copied some files or if you have the same songs in original albums and compilations. To use this, select File > Show Duplicates. This will show all tracks with the same name and artist. If you hold Option while selecting File, the menu item will change to Show Exact Duplicates, which will filter out duplicates with the same name, artist, and album. Go through these files carefully and you may find some you can delete, saving space on your Mac and on your iPad or iPhone. Safari has some features that can take up unnecessary space. For example, cache files are intended to speed up browsing, but they can easily get into the hundreds of megabytes and actually slow things down. History files can bog down Spotlight searches. And “Top Sites,” “Website Preview Images,” and “Website Icons” can slow the program down. It's a good idea to reset Safari from time to time. Select Safari > Reset Safari, then check the items that interest you. Don't reset or delete everything. Choose what's most important to you, and reset Safari periodically to speed up browsing and save disk space.
