Before setting up your Motu M2 audio interface to work with the JamKazam app, you must first set it up to work properly with your Mac computer.
If your Mac doesn't have Thunderbolt 3 ports, then you cannot get the latency reduction benefit from the Motu software driver, so we'd suggest you skip the installation of this driver, and skip this whole help article. You can just use the Motu M2 in plug-and-play mode, so move ahead to the help article on how to start the audio setup wizard.
On the other hand, if you have a modern Mac with Thunderbolt 3 ports, then you should install a piece of software called a "driver" that was developed by Motu. This software driver controls the operation of the audio interface hardware as it interacts with your Mac, and it will reduce your audio processing latency all the way down to a super speedy 4 milliseconds.
Following are instructions on how to: (1) download the latest/greatest version of the software driver for your Motu M2, and yes it's important that you use the latest version of the driver software; and (2) install the software driver on your Mac computer.
To get started, open your browser, and go to https://motu.com/en-us/. Click the Downloads link near the top of the page (pictured below with arrow).
You now see the Downloads page (pictured below).
Scroll down the Downloads page until you see the section of the page titled "MOTU Product Downloads". Click the blue Download button under the M2/M4 header to download the Motu driver software for Windows (pictured below with arrow).
You will see the driver file downloaded through your browser in the way your browser typically downloads files from websites (pictured below with arrow). Click the downloaded file to open it.
Run/start the installer, and you now see the first screen of the Motu installer. Click the Continue button (pictured below with arrow).
You now see a screen that asks you to review and agree to the Motu software license agreement. Click the Continue button (pictured below with arrow).
You now see the next screen of the Motu installer. Click the Install button (pictured below with arrow).
You now see a Mac system prompt asking if you want to allow the Motu installer to make changes to your Mac. Either use the Touch ID feature, or click the Use Password button to enter your Mac system password to allow the installer to run and install the Motu software driver on your Mac.
After entering your password to establish your identity as the owner of the Mac computer, click the Continue Installation button to allow the installer to run.
The Mac operating system has a bunch of new security features, and it's now going to also make you open your Mac's security preferences to give permission yet again for the installer to do what it needs to do. Click the Open Security Preferences button (pictured below with arrow).
You now see the Security & Privacy section of the System Preferences on your Mac. Click the lock icon to make changes (pictured below with arrow).
Here again, either use Touch ID or enter your Mac system password to complete the unlock to give permission for the installer to make its changes (pictured below with arrow).
Now that you've unlocked the Security & Privacy section of the System Preferences on your Mac, click the Allow button to let the Motu installer make its changes (pictured below with arrow).
The Motu installer now (finally) is able to finish running and installing the Motu software driver for the M2 audio interface. Yay! Click the Restart button (pictured below with arrow). This will restart your Mac computer, so make sure you've saved any work you have open in any applications that are currently running before clicking this button.
You have now successfully installed the Motu M2 software driver.
Your next step in the setup process is to configure your audio interface to work with the JamKazam application. Click here for instructions on how to start the audio setup wizard to do this.
