Do you see the LP-16 in the Audio Midi Settings panel?

Updated to the latest firmware… [/quote]
To update the firmware it require a proper connection, so I assume your device connected successfully. Do you have a chance to check in any other application (like reaper etc)
Ok so on another MAC more less worked I mean at least successfully connected, so I assume the device from hw perspective working.
Could you please make sure you have no USB drive connected to the LP-16 when you try to connect to your MAC, and also make sure the device shows “USB interface mode [MAC] on the screen.
Please try one another USB cable and an another USB port on your MAC.
