The following information will help you troubleshoot in the event that a Mac computer does not recognize the Rubix:
Note: The Rubix 24 is compatible with macOS 10.13 or later. Earlier operating systems are not compatible and there's not a workaround to allow compatibility.
- Check if the Mac is identifying the Rubix:
-
- Connect the Rubix 24 to the computer and then power on the Rubix.
- Click on the Apple icon on the top left of the screen and then select System Preferences.
- Click on the Sound icon and then click on the Output or Input tab.
- If the Rubix appears in the list, then computer recognizes the Rubix and everything is working properly.
- If the Rubix does not appear, continue with the troubleshooting below.
-
- 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.
- Test with a different USB cable that's connected to the USB-C to USB adapter (if available).
-
Connect directly to your computer via USB. Do not connect to a USB hub while troubleshooting.
- Try a different USB port on the computer.
- Be sure that only the included Roland brand PSB-120 or PSB-1U power supply is being used--3rd party power supplies can cause the unit to not operate properly.
- 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.
- Install the latest version of macOS.
