I’ve hacked together a way of getting my 4x MOTU 24I/Os (and likely all other MOTU PCI / PCI-E devices) working on newer version of MacOS.

I’m fucking pissed off with unnecessarily dropping support for hardware – especially stunningly expensive, niche hardware. Not only would it cost me a small fortune to replace the 24I/Os, but I’d spend weeks rewiring my studio.

Right so, to get these fuckers working on you newer MacOS device here’s what you need:

SOFTWARE

• Download MOTU Audio Installer 1.6 (73220).pkg
• Download MOTU Audio Installer 1.6 (83634).pkg (yes, both)
• Download Pacifist

PROCESS

Open Terminal are do the following: “sudo mount -uw /”. This mounts the System partition of MacOS and makes it writable. This is where we’ll be installing the drivers.

Open MOTU Audio Installer 1.6 (73220).pkg with Pacifist. You should see the following.

Right click on “Contents of PCI_and_PCI_Express_Drivers.pkg” and select “Install to Default Location…”

If you receive any errors at this point, it’s likely that your System partition isn’t writable. Go have a look on Google to see what you need to do.

Next, we need to open the newer MOTU Audio Installer 1.6 (83634).pkg with Pacifist. First thing I should draw your attention to is that those cunts have removed the PCI_and_PCI_Express_Drivers.pkg.

So now we need to install the applications by opening “Contents of Common.pkg / Applications” There you should see “CueMix FX.app”, which for my purposes is required to get my set up customised to how I needed it. The drives should work without this, but you’d be missing some functionality.

Anyway drag “CueMix FX.app” to your Applications folder and restart your computer. After a reboot you should now see that everything is working as it should.

Since we don’t have an app to allow us to change the sample rate of the device now, this can be done natively in MacOS “Audio Midi Setup”
