disable siri permanently in big sur Every time my Big Sur Macbook Pro does an automatic overnight update and reboots, it presents a checkbox offering to enable Siri.  Can this perpetual nag be disabled?
(In System Preferences, I leave the checkbox &quot;Enable Ask Siri&quot; unchecked.)
One way to do this is via MDM policy.

If you don’t have an MDM, I recommend trying JAMF now for free since it is supported and free for the first few devices. You can fine tune things like the menu bar as well.

You might try these profiles as well but that operation can be fiddle without the MDM setup completed.
