Rubix 22: SYMPTOM: Computer Does Not Recognize the Rubix (macOS)

The following information will help troubleshoot in the event that a Mac computer does not recognize the Rubix 22:

Note: The Rubix 22 is compatible with macOS 10.13 or later. Earlier operating systems are not compatible and there's not a workaround to allow compatibility.

1. Power:
   1. 1. Connect the Rubix 22 directly to the computer (no USB hub) via USB and then power on the Rubix 22 by setting the POWER SOURCE switch on the back to the right (towards ).
      2. If using an external power supply, connect the the Rubix 22 directly to the computer (no USB hub) via USB. Then connect the Rubix to the external power via the 5V DC jack on the back and set the POWER source witch on the back to the left (towards 5V DC).
2. Check if the Mac is identifying the Rubix:
   
   1. 1. Click on the Apple icon on the top left of the screen and then select System Preferences.
      2. Click on the Sound icon and then click on the Output or Input tab.
      3. If the Rubix appears in the list, then computer recognizes the Rubix and everything is working properly.
      4. If the Rubix does not appear, continue with the troubleshooting below.
3. USB
   1. IMPORTANT NOTE: Do not use a USB cable that is designed only for charging a device. Charge-only cables cannot transmit data. Check the documentation of the cable being used to be sure that the cable is not designed for charge-only.
   2. Be sure to use an Apple brand USB-C to USB adapter--or at least a name brand. 3rd party adapters can be less reliable than Apple brand.
   3. Test with a different USB cable that's connected to the USB-C to USB adapter (if available).
   4. Connect directly to your computer via USB. Do not connect to a USB hub while troubleshooting.
   5. Try a different USB port on the computer.
   6. Disconnect all other USB devices from the computer (except for the mouse and keyboard)--for troubleshooting purposes. If the issue is resolved, troubleshoot the USB device that's interfering with the computer's ability to connect to the Rubix 22.
4. Install the latest version of macOS.
5. Test on a different computer (if available) to pin-point whether the issue is due to the Rubix itself or with the original computer being used.
