Studiomux driver not installing macOS

Hi everyone -

I’m having trouble with the install of studiomux on my Mac. I’d like to connect my iPad and use it with Logic X for both audio/midi.
It seems that the “Studiomux.driver” is not installing. I can see AudioMux.driver, but not the other. As a result, when I open audio/midi setup, to create an aggregate device, Studiomux never shows up. I’ve given it permission in system settings. I’ve tried uninstalling, reinstalling, rebooting, etc.

According to chatGPT, “If you only see Audiomux.driver in /Library/Audio/Plug-Ins/HAL/ and no Studiomux.driver, then your Mac is only loading the old Audiomux extension. That’s why Studiomux never appears in Audio MIDI Setup — the system literally has no Studiomux CoreAudio driver to load.”
Hopefully someone can help.
Thanks
Stuart
