After installation of our Mac product on macOS High Sierra, a red F-Secure (X) icon may appear when running real-time scanning.


This is due to a new security feature, which has been introduced with macOS High Sierra (10.13) or higher. During first time installation, the security feature requires you to allow system software from F-Secure. Until the software is allowed, real time scanning will fail.


Once the installation is complete, allow F-Secure software as follows:

  1. Go to System Preferences > Security & Privacy, and select the General tab.
  2. Click Allow.
Once this is done, the icon status changes to normal and the error message disappears.
