MacJanitor allows you to manually startup daily, weekly, and monthly cron maintenance scripts. These scripts are important when keeping MacOS X in "good shape". Usually, these scripts are set to automatically launch at times of the day when little activity occurs. However, if your Mac is turned off during these times, then the maintenance scripts don't have a chance to run.
What's new in MacJanitor
Built for Panther and higher (Tiger compatible).
Uses the 'periodic' tool instead of running the tasks directly.
