I want to edit my crontab file to schedule a script. Where do I find it?

If you don't want to use launchd, you can edit your crontab as you would do on any unix systems :

crontab -e

Or, you can use a GUI software like CronniX.

And if you want to see your crontab content use crontab -l – Ermiar Sep 4 '10 at 13:06
I would highly recommend CronniX. It provides a much (much!) easier way of setting up cronjobs. – daviesgeek Nov 10 '11 at 7:52

In OS X Lion the user crontabs are stored in /var/at/tabs. In the past they were located in /var/cron/tabs.

You should use crontab -e to interact with these in general, but knowing the location is useful when you want to restore them from a backup of our disk, or something similar.

In Snow Leopard, the user crontabs are stored in /var/cron/tabs, as well. – Jack Humphries Nov 22 '14 at 16:22

The OSX way is to use launchctl to run jobs at a time. For ease of use there is a GUI called Lingon
