Yes, it does. The main one to use is Repair Permissions. Open a Finder window, click Applications on the left sidebar, scroll down to the Utilities folder, double click Disk Utility, click on your hard drive on the left sidebar, then click repair permissions.

Another one is restarting holding the Shift key until you see the Apple logo then let go of the Shift key. This is known as starting up in Safe Mode. Safe Mode runs system diagnostics automatically. After the computer starts up completely, restart again without holding any keys down and you'll be back to normal mode.

One more is running Disk Repair. Restart, as soon as you hear the startup chime hold the Command S keys. You'll get a Unix text screen. When the prompt come up type:

fsck -f

make sure there is a space between k and -. When the diagnostics say the computer seems to be ok type:

reboot then hit return and you'll start up back to normal

These are pretty much all you'll need. Mac OSX automatically defragments files 20 megs or less so, there's really no need for a defragmenting software.
