C. Updating the Driver
Introduction
The MIO Driver is the conduit between your interface and CoreAudio. We occasionally update the driver to
provide new features, fix bugs or maintain compatibility with new Apple operating systems.
Updating the driver is a simple process, but there is a definite procedure that should be followed:
1. Quit all software.
2. Disconnect your interface(s) from your computer.
3. Double click the driver installer package and use the Apple installer to update the MIO Driver package.
You will be required to reboot your computer.
4. Make sure your interfaces are powered up and connected to your computer.
5. Run the MIO Console.
6. Go to the I/O tab of the Console Window and confirm that the interfaces are online and that the driver
version in the lower right of the window is correct.
If the MIO Console installer contains a newer version of firmware than the one installed in your interface, you
may upgrade the firmware now. Instructions are available in the
Updating your Firmware appendix.
