After you get a new and/or re-imaged VCSU MacBook or Mac computer and after first boot up, you will get a message from BitDefender about "System Extension Blocked". Please follow the simple steps below to allow the Anti-Virus application.


Message you will see from BitDefender:

Mac Bitdefender full disk access notice

1) Click the "Open Security Preferences" button.


2) From the "General" tab click the "Allow" button:


*Note: after clicking allow, you may get a couple prompts about restarting BitDefender and/or a System Extension Warning, just accept them and continue.


3) Restart your Mac and once you are logged back in, open BitDefender:


4) Confirm that BitDefender is all green and this would be a good time to run a full scan (this can take some time, make sure you are plugged into power):



Once that is done, you should be all set!
