@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.
