Making terminal administrator permanently in macOS Big Sur. Every command gives error "“Terminal.app” would like to administer your computer." [duplicate]

I keep getting a warning message that terminal would like to administer my computer whenever I run standard commands, such as editing crontab in Vim. This never used to happen on my old Macbook. How do I turn off this feature?

These are new(ish) security features that have been gradually introduced in recent macOS versions. Apple noticeable ramped up these security controls with the release of mojave.

The system noticed that Terminal was being used to access files that aren't normally edited by end users. (Were you attempting to edit the crontab for the root user? ... i.e. sudo crontab -e?

The command line utility that can control this is tccutil.

To reset warnings associated with the Terminal app, you can use tccutil reset All com.apple.Terminal. This will reset permissions and warnings associated with Terminal back to factory defaults ... but from here you would be allowed to grant permissions to Terminal.

You need to give Terminal 'Full Disk Access" in System Preferences > Security & Privacy.

Choose Full Disk Access in the sidebar, and then unlock the padlock and enter an admin password. Then click the + button and add the Terminal application.
