Hi there,

I had the same problem with enabling the firewall on macOS Monterey.
Here you can find the solution that worked for me: https://service.mcafee.com/?articleId=TS103081&page=shell&shell=article-view

Kind regards,

The first step in the solution on the webpage, that the link directs to, worked for me. The system extension was blocked for Mcafee in my case. Allowing it from system preferences fixed the issue. Thank you.

Re: Cannot enable firewall on MacOS

Jump to solution

Can anyone help me.  I've had McAfee Livesafe protection subscription for a few years but some months ago when my Mac updated to Big Sur OS, it stopped working and I uninstalled it.

I recently had an email from McAfee confirming my subscription was renewed and providing me a link to re-download the software and install it again which I did a few days ago.

However the Firewall will not turn on.  I have followed the first prompt which was about changing OS system settings to provide full disk access (or similar) and it still won't turn on.  I have read this discussion board and followed the advice below (changing settings from Public to home or Work) and still it won't work.  

Can someone please help ?

 

Thanks Neil

I did a new install, and still can't enable Firewall. Anybody has a solution? I already have Full Disk access and those steps have been taken care of. Please let me know. I opened a case with McAfee couple of years ago and had to remove from my MAC since there was no solution at that time
