Cron is a well-known tool for scheduling jobs in Unix-like operating systems. However, cron was depreciated in macOS. As the documentation states, although it is still supported, cron is not a recommended solution. In addition to the reason, if you don't have permission to install the crontab, you will see the error message "Operation not permitted" when saving the crontab file. This post will show you how to run scheduled jobs using Mac Automator, an alternative to cron.
