Background
Any time you install new software or update existing packages with Apple's pkg installer system you may find that you computer becomes a little unstable. It does not need to be so. The standard solution is to run the Repair Disk Permissions function of Disk First Aid. Under Mac OS X 10.2x (Jaguar) this is part of the Disk Utility (/Applications/Utilities/Disk Utility). However, most of us forget to run this after an update...
So why not automate this? Mac OS X has a built in facility for doing just that: the cron daemon.
Installation
Step 1: Install the run-parts Script
If you haven't done this already, install the run-parts script.
Step 2: Install repairperm
After downloading repairperm, copy it to the appropriate /etc/cron directory. I recommend doing this at least once a week. Daily may be a bit much, however. We can copy the file from your download location using the Terminal (/Applications/Utilities/Terminal). For example:
$cd location_of _repairperm $sudo cp repairperm /etc/cron.weekly
That's it!
