OK, this is a simple tip, but I wanted to get the ball rolling. Rebuilding your Desktop is easy and will make your Mac run more effeciently. Simple press and hold the command (apple) and option keys at startup and you will eventually be presented with a window that asks you if you want to rebuild the desktop. Just click "OK" and you're off. You really should try to remember to do this once a week or so.<br><br>
