2011 MAC machines use first generation Thunderbolt™ ports. From time to time these might reject connection with our (and not only) devices.
If you experience this issue, please try the following steps:
- Remove the driver
- Disconnect the Thunderbolt™ cable from the computer
- Power off the computer
- Start the computer and plug the Thunderbolt™ cable in
- Re-install the driver
- After installing the driver, don’t disconnect the unit and don’t restart the computer
- Check if the device is present in audio midi settings and control panel
This workaround has solved the issue for some of our users.
Please be advised using USB is prefered on 2011 Macs due to the stability issues encountered by the 1st revision of Apple thunberbolt ports
