How to get an esp32-S2 recognized as USB device on a mac

[Arjuna_1000]

I have an esp32-S2 saola and I am trying to use it as a MIDI usb device. I am trying to use this github repository: https://github.com/chegewara/EspTinyUSB. I am able to run the code on the esp32s2 saola and I am connecting to a mac with a USB cable to pins 19 and 20 but don't get any MIDI input in my computer (mac), in fact my computer is not recognizing the device.

So I guess my actual question is about how to get the esp32s2 recognized as a USB device by the mac. Any clues of what might be happening? Or should connecting to pins 19 and 20 be enough and I am dealing with a hardware bug?

For the usb cable I took a usb only-power cable apart and then rewired it so it was only data (two middle cables connected to pins 19 and 20). As it was not working I then connected also the usb's power and ground cables with no luck (picture attached).

I found that Apple products don't play nice with any other manufacturers products which is why I give them a wide berth. Good luck.

Likewise, I wouldn't touch Apple products with a bargepole.

We make a simple BlueTooth adaptor (using a Chinese module) for a device we sell - but Apple don't support the common standard it uses, so it's Android only.
