MacJanitor is a free Mac OS X system maintenance tool. It is a very simple app that serves a very specific function.
When you run the application, you have to click on the little "lock" icon to gain administrator privileges. This will bring a window up where you have to type in your user password. Once that is done, you can click on the daily, weekly, and monthly buttons to carry out those system maintenance operations. Or, you can click on "all tasks" and do them all at once. When you click on one of them, the application will show a text log on the main screen that shows exactly what is done. The information is a bit technical, though.
In my testing, doing all the tasks took a little under 20 seconds. I really didn't notice any change in my system in terms of speed. But different users will probably get different results.
Pros
- Advanced scheduling
- Automated maintenance
- Detailed statistics
Cons
- May crash when starting a scheduled action
