MacJanitor for Mac OS X

Updated 2 days ago

MacJanitor is designed to be used on a periodic basis by Mac OS X users who don’t leave their computer on (and awake) 24 hours a day.

The Unix subsystems on Mac OS X were originally written for machines that were typically never shut off. Mac OS X inherits this assumption in version 1.x, and has many system maintenance tasks that are scheduled to run between 3 am and 5 am. In addition, there are scripts designed to run weekly on weekends, and once a month in the middle of the night.

If these maintenance tasks are never run (such as on a laptop that is always shut off at night), many log files and system database will grow extremely large or fail to get backed up.

MacJanitor provides a way to run these system tasks at the click of a button. Laptop users could click the ‘daily’ button every morning (or every few days), or office workers could click the ‘weekly’ button on Mondays.

If you’ve been leaving your machine off at night without allowing the maintenance tasks to run for several weeks or more, the first time you run them using MacJanitor may take several minutes. Also, if your log files have grown extremely large and you are low on disk space, the tasks may have problems moving the files around and compressing them. After that, it typically takes less than a minute for each task.

The output of the task is displayed in the scrolling view in the bottom part of the window. If for some reason you feel the need, you may print the output of the system maintenance tasks (but why?…).

You can’t really hurt anything by running the tasks more frequently than is intended, and they don’t need to be run on a strict schedule. Just run them periodically when you get a free minute every few days or weeks.

MacJanitor is provided as freeware as a service to laptop and energy-conscious home users.
