Maintenance Scripts

Friday, April 18, 2008, 10:28 PM – Tips and Hints

You know, the OS X Mac operating system really is a thing of beauty. I can say that with a straight face, knowing that I don’t understand squat about how it works.

That doesn’t keep me from appreciating the beauty of it though. It just all fits together so well in so many ways. One of the reasons that it keeps running so smoothly is the maintenance scripts that it runs overnight.

These scripts clean up a variety of system logs and temporary files. By default, they are executed between 3:15 and 5:30 a.m. local time, depending on the script. If your Mac is shut down or in sleep mode during these hours the maintenance scripts will not run. This results in log files that will grow over time, consuming free space on your startup disk.

I personally never restart my Mac more than once every two weeks or so unless I am installing software that requires a restart as part of the installation. It does not harm the computer to run all the time as long as you have it properly ventilated so that it does not overheat.
