Macaroni is a tool which handles regular maintenance for Mac OS X's UNIX core. Normally these tasks run on a regular schedule, in the middle of the night. However if you don't leave your Mac on all night, they never run. Your Mac won't wake from sleep to handle this. Macaroni solves this problem. If a scheduled maintenance task is not run when it's normally scheduled, Macaroni automatically ensures that it's run at the next opportunity, whenever the Mac is on.
