If you have already installed the driver on an earlier version of macOS and upgraded to macOS 10.13 High Sierra or later, you should not need to enable the driver. This behavior will only occur when installing a MOTU driver for the first time on macOS 10.13 High Sierra or later.

To display the Allow button, run the installer for the MOTU driver again.

To enable the MOTU drivers, follow these steps: If your MOTU interface is not showing up in Audio MIDI Setup, MOTU Audio Setup, MOTU Discovery, or your DAW on High Sierra or later, you might need to enable the driver in your System Preferences. Due to the updated security architecture introduced since macOS 10.13 High Sierra, the system extensions for all newly-installed third-party software will automatically be blocked from running.
