How To Change Settings of Startup Security Utility Mac?

Full Security offers the best security for the system and is thus the default option. If you click on this option, the Mac will verify the condition of the OS on the startup disk and make sure there are no issues. If the OS can't be verified as being legitimate or there is a lack of information, more information is downloaded. Still, if the OS doesn't get the verification, an alert is given for a software update. 

If you choose Medium Security, the steps taken are not too severe. In this case, the Mac verifies that the OS is properly signed or not. It, however, doesn't prevent the system from using that OS. In case of failed verification, the user gets an alert for the software update. 

If you opt for the third option, No Security, you don't have to worry about anything. There will be no security steps taken. The OS will not be verified. 

The Allowed Boot Media section comes with two options. These are – Disallow booting from external or removable media and allow booting from external or removable media. If you choose the first option, the Mac will not start from external media. In case the user attempts to do, a warning is given.
