Driver alert keeps showing up

Usually, the following driver alert will appear on first start-up and the alert will disappear after you allow the system software from System Settings.

Unfortunately, the allow button may sometimes not appear in System Settings due to a problem with macOS driver loading.
In this case, you can display the allow button by deactivating and activating driver as described in the Advanced section on the alert.


macOS Catalina Notes

Karabiner-Elements requires macOS 10.15.6 or later, because macOS 10.15.5 or earlier has an issue around DriverKit.

Please use Karabiner-Elements 12.10.0 if you are using macOS 10.15.5 or earlier.
