Why is my Apollo 16/16 mk II not being recognized by my computer via Thunderbolt?

Note: This article only applies when using an Apollo 16/16 mkII via Thunderbolt.

There are a few common things that can cause the Apollo 16/16 mkII to not be recognized by the computer. Here's what to check if you're getting the 'No Devices Found' message in the UAD Meter:

Check Thunderbolt Cable Orientation

When connecting Apollo 16/16 mkII to the computer always check the orientation of the Thunderbolt cable. The Thunderbolt logo must be face up on the Thunderbolt cable when plugged into both the Apollo 16/16 mkII and the computer - if the Thunderbolt logo is not face up then the cable is inserted upside-down, which can be done fairly easily. 

Note: On iMac computers, the Thunderbolt logo on the Thunderbolt cable should face left (when looking at the back of the iMac).

Check Computer Compatibility

Apollo 16/16 mkII cannot be used by connecting it to a Mini DisplayPort connector. Although Thunderbolt and Mini DisplayPort devices have the same physical connector, the underlying communication protocol used by these devices is different and the Apollo 16/16 mkII will not be recognized when connected to a Mini DisplayPort.

The type of device port can be determined by the icon next to the port. Thunderbolt ports have a "lightning bolt" icon, while Mini DisplayPort ports have a "display" icon. The difference between these ports and icons is shown in the illustration below.
