Troubleshooting

A
APPENDIX
My MOTU interface isn't showing up in Audio MIDI
Setup on my Mac.
Due to the updated architecture of the new macOS
High Sierra (10.13) or higher, the system
extensions for all newly-installed third-party
software will automatically be blocked from
running. If your MOTU interface is not showing
up in Audio MIDI Setup or your DAW on High
Sierra or higher, you might need to enable the
driver in your System Preferences. To do so, first
download and install the very latest installer for
your MOTU M Series interface. After restarting,
open System Preferences. Select Security &
Privacy. In the General section, click the Allow
button. The Allow button will disappear 30
minutes after installation. To display the Allow
button, run the installer for the MOTU driver
again.
I can't hear computer audio output through my
MOTU interface.
In the Sound panel of System Preferences, the M2
or M4 should be selected as the output device.
How do I monitor live inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the hardware monitoring feature in your M
Series interface. Please see "Monitoring through
the M2 or M4" on page 20.
How do I control monitoring latency?
See "Reducing monitoring latency" on page 20.
How do I factory reset my device?
Power off the unit. Press and hold the Input 1
MON button and while doing so, power on the
unit. You should see several small white dots
below the MOTU logo on power-up. These dots
indicate that the factory reset has commenced.
Wait a brief moment. When the normal level
meter screen appears, this indicates that the
factory reset is complete.
Connecting or powering gear during operation...
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the M2 or M4 while recording or playing back
audio. Doing so may cause a brief glitch in the
audio.
