Operation not permitted when running a script from crontab

In the Full Disk Access preferences, click on the + icon

press: Command-Shift-Period

This will show hidden files in file select dialog window.

navigate to the directory with cron

select cron

You press the Command-Shift-Period keys again to toggle the showing of hidden files so they are hidden again.

It sounds like whatever user is running the Cron job does not have access to your documents, folder. bash and Terminal are not the users in this case.

I don’t use cron, so I’m not sure, but I think cron runs as root, and root probably doesn’t have access to your Desktop, Documents, and Downloads folder per Ventura’s privacy model.

You may be able to set it up to run as your user, but that’s beyond my knowledge of cron.

Does the script run on files in your Documents folder? If not, you could move them to a location that root can access. I would avoid trying to give root access to the Privacy protected folders.

I've seen a similar question posted on these forums a few months ago with a possible solution(s). However, I don't recall the details.

While trying to search for the thread, I did find mention that "cron" may need to be give "Full Disk Access" in the System & Security System Preferences.
