My S88 Mk2 stopped showing up today on my Mac Studio (MacOS 12.6). It is connected via USB (in a hub with other USB ports, but I have checked it by plugging in directly).
No midi input in Cubase, "Komplete Kontrol S88 Mk2" is greyed out in Mac Audio/Midi setup, lights on the keyboard are not the usual color (pink).
I plugged the Mk2 into my old mac and the keys lit pink straight away, so the keyboard/cable appear to be working.
Nothing has changed or updated on the Mac since I last used the keyboard two days ago.
I followed the troubleshooting tips here: https://support.native-instruments.com/hc/en-us/articles/4410096148113#troubleshootingdriver to no avail. the device doesn't show up in the USB hardware list in system information.
I reinstalled the Komplete Kontrol and Controller Edit apps from Native Access, rebooted both the computer and keyboard several times.
Not sure what else to try. While silicon macs may not be supported, it was working fine for like a year and then suddenly wasn't.
