My Minilab 3 was working on my older intel macbook pro, but it doesn’t work with my new Macbook Air 15" 2023. I also tried it with a Macbook Pro 16" 2023.
I tried different cables - no luck.
I tried removing all other peripherals - no luck.
The device gets powered on, but is not detected. And it does not show up in the Mac Audio Midi Setup - Midi Studio.
Solved! My monitor has a dock built in. I had to connect the Minilab 3 to the dock rather than directly to the computer and now it works. Very strange as I was able to connect it directly to my old computer. Maybe the new macs remember that you usually use a dock and defer to that USB route.
