I am also having the exact same problem of not being able to turn on Firewall.

@emichaelson

Please check the steps below and if you still have the same issue, let us know the Firewall version from McAfee About screen

  1. Mac Firewall should be disabled
  2. No third party Firewall/Antivirus app is installed, If any installed, please remove them
  3. Update McAfee and restart the computer
  4. If any security update is available from Mac OS, please install them

Regards,

Karthik K

Thanks to all for comments. The solution was to completely uninstall the product and reinstall it. The firewall could then be turned on.

I have the same configuration and uninstalling and reinstalling the product fixed it for me.

I had the same problem, and I solved it by doing the following:

1. Go to System preferences on your Mac

2. Go to Security & Privacy

3. Enable modifications by unlocking the lock icon on the bottom left

4. Go to Full disk access

5. Make sure that the McAfee Network Extension is enabled.

This should fix the problem without having to reinstall McAfee. Hope this helps.
