I am brand new to Audacity. I am running on a 2012 MacBook with MacOS 10.13.6 High Sierra. I have Audacity 10.4.2.

I want to connect my MOTU 8Pre with firewire output into Audacity. I also have my output going to the MOTU as well. Is there a way to do this?

Connect the MOTU to the Macbook. Go to Apple menu > System Preferences > Sound > Input. Does the MOTU show up there as an available input? If so, you should be able to select it in Audacity’s Device Toolbar.

Similarly, in the Input section of Sound Preferences, does the MOTU show up as an available output? If so, you should be able to select it in Audacity’s Device Toolbar as an output.

Thanks for the response Bill - I am running Audacity 2.4.2 NOT 10.4.2… My bad.

I checked as you indicated and, when the MOTU 8pre is hooked up, it does not show up in the Apple Preferences as a choice.

Too bad.


See also this note on the MOTU web site: - Enabling MOTU drivers in macOS 10.13 High Sierra or later

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. 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.

  1. Download and install the very latest installer for your MOTU interface.
  2. After restarting, open System Preferences.
  3. Select Security & Privacy.
  4. In the General section, click the Allow button.

I hope this helps.

Well, this looks promising!

Thanks Jademan!
