Arudino Nano Every not recognized on M3 Macbook Air

Official Hardware Nano Family Nano Every

Hello,

I am trying to program an Arduino Nano Every on my M3 MacBook Air, but the board is not recognized at all. It does not appear in the connected USB devices (System Report) and is also not listed in the Arduino IDE under Ports.

However, when I connect the same board to another Intel-based Mac, it works fine.

I have already tried the following:

  • Installed all necessary drivers, including the Arduino megaAVR board package.
  • Switched to a different Arduino Nano Every, but the issue persists.
  • Tested the same USB-C adapter and cable with an Arduino Uno, which works fine.
  • Checked System Report → USB and ls /dev/cu.usb* in the terminal, but no new device appears when plugging in the Nano Every.
  • Tried entering bootloader mode (double-pressing the reset button), but still no detection.

Has anyone experienced a similar issue or found a workaround for M3 Macs or Apple Silicon in general?

Any suggestions would be greatly appreciated!

Those are two very different things. Exactly what drivers did you install, CH340, CP210, FT232?
What USB/UART chip is on the board?

I don't know anything about Macs.

An Uno uses a normal USB-B connector, a Nano Every definitely does not use that. So I'm confused.

How about an ATSAMD11D14A with dedicated firmware :wink:

I think i misphrased this. I use an external USB Adapter/Hub to connect to the Mac. That same Adapter works perfectly fine with the Uno. The cable and the nano also work but on a different Mac. So i believe none of the parts themselves are faulty, but rather a driver or setting on the Mac.
