Maybe this will save someone a LOT of time and aggravation.
Just installed Mac OS Mojave and it broke all sorts of stuff including my Cubase AI (V 10.0.20) … specifically NO audio input into Cubase possible, period. Tried everything, including reinstalling Cubase, various audio/midi drivers etc. Nope … Mojave problem.
Additionally, Mojave now constantly drops my Bluetooth connection to mouse AND keyboard … maybe it comes back, maybe it doesn’t. Wait … wait … OK hard reboot … super aggravating. And … and … and.
Reinstalled High Sierra and everything is back working fine as before, so yes it’s Mojave.
