tuning up your mac

I am a mac person I find windows machines unnecessarily complicated, as those who switch to macs quickly realize. But no personal computer is so carefree that you can run it forever without have performance degrade over time. Each time you save to your computer’s hard drive, the system has to find a place for that data. Imagine throwing the inventory of a toy store into a store room, willy-nilly. Not in boxes, mind you, just piece by piece. You’d have chaos, right?

Now imagine trying to find a matching pair of doll shoes in that mess. Ugh, what an ordeal! Well as much as your drive tries to store things in some kind of order, over time it may not find there’s enough room to store matching data in one place, so it breaks it up, fitting each bit in to the cracks and corners that it finds available. That makes retrieving data a slow and tedious process. For optimum performance, at least 30% of your hard drive space should always remain free to give the computer space to move things around when it’s reorganizing. If your hard drive is almost full, performance will slow to a crawl.

To completely defragment your drive, you’d have to copy all your data to a backup, reformat your drive and then copy your data back to it, or use a third-party defragmention utility. But there are options you can try first that just might clean things up and get you on your way.

First, go to Applications—> Utilities—>Disk Utility. Start Disk Utility and select your hard drive in the left hand column, then click "Repair Permissions." Run this over and over until there are no permissions left to repair. 

Next, find your system disk and insert it into your cd drive. Restart your computer, holding down the "C" key while you do it. In the Mac OS X Installer window, click OK on the first screen, then from the top menus, choose Utilities—>Open Disk Utility. Select the startup disk you want to repair in the list of disks and volumes, then click “First Aid” tab. Click “Repair Disk.” When it says the disk repair is complete, quit Disk Utility, then quit the install disk- you will be given the option to restart.
