Ever have that annoying spinning beach ball ? This is one way to aid against that.
A simple way to make your Mac OS X system run smoothly is by booting your system up using your “Mac OS X” Software CD that came with your computer.
Put your CD/DVD in your drive and restart your Mac. Hold down “c” on your keyboard when you hear the start up chime. Alternatively you can hold down “option” key and get the option of different start up disks to choose from. Choose the CD.
From that point on, Mac OS X should be booting from the CD, and it should make whirring and seeking noises. You can click OK, Continue buttons until you see the Apple menu appear at the top.
GO TO the UTILITIES menu > DISK UTILITY
Click on your Hard Drive icon on the left of the window that appears.
Choose, on the right, REPAIR DISK PERMISSIONS wait for task to complete.
Choose REPAIR DISK, and wait for task to complete.
You have successfully maintained your drive.
