If you see this message, you'll need to approve the loading of the KEXT manually so that your
device drivers can be loaded and you can continue to use its functionality with our software. To
allow KEXT loading, please open System Preferences and navigate to the Security & Privacy
section. On the General tab, you should see a message and an Allow button, as shown below. In
order to load the drivers, click Allow. You may need to reboot your system so the drivers are
properly loaded and the functionality of your mouse is restored.
NOTE: As set by the system, the Allow button is only available for 30 minutes. If it has been
longer than that since you installed LCC or Logitech Options, please restart your system to see
the Allow button under the Security & Privacy section of System Preferences.
