Realtime scanning is not enabled on Mac computer with High Sierra or Mojave
F-Secure Computer Protection / F-Secure SAFE is installed on a Mac computer but the user interface shows that computer is not protected and that the real-time scanning is not activated.
After installation of the 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 in 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:
Go to System Preferences>Security & Privacy, and select the General tab.
Click Allow. Once this is done, the icon status changes to normal and the error message disappears.
Note: The steps described must be performed locally on the machine and not remotely.
