Yamaha Steinberg USB Driver version 1.9.9 and earlier might cause macOS to stop responding and unexpectedly restart when unplugging or turning off connected Steinberg devices. If that happens, you're given the option to move components of this application to the Trash. That disables Yamaha Steinberg USB Driver to prevent the issue from happening again.
Download Yamaha Steinberg USB Driver version 1.9.10 or later, or contact Steinberg to check for an update that is compatible with the macOS version you’re using.
