osascript wants access to control system events

Hello AmitSh,

​Thank you for using the Apple Support Communities. If I understand your post correctly, you're being prompted to allow access when you activate a Google Drive account, and you're finding the account doesn't work if you don't allow the requested access; is that right?

Try clicking Apple menu () > System Preferences > Security & Privacy. Then, click the Privacy tab, followed by Accessibility in the left-hand column. This is typically where you would be able to see which apps are requesting control access, and where you can allow or deny these requests. Do you see Google Drive here?

I hope this helps get you started.

Cheers.
