How to Find Cron Jobs on a Mac
Cron jobs or cron tabs are automated scripts developed originally in Unix operating systems. Cron jobs are scripts developed to run periodically at various times to perform maintenance tasks.

Three cron jobs are built into the Linux operating system as maintenance tasks to clean up system files.
