When I connect my Arduino Nano onto my Mac with provided USB cable, the PWR light blinks once red and then switches off immediately (same when connecting to other computers, incl. Windows). And on the IDE I can't see thee port (FTDI chip). Nothing else is connected on the breadboard.
When I connect a battery to it, the PWR light remains steady red.
Where should I look at ?
Thanks
Try a different USB cable, they quite regularly fail.
I tried but same issue. So I bought the latest Nano ESP32 with USB-C, and connected it using a new USB-C cable (certified data) to my Mac, but Arduino IDE still does not see any serial port.
Is there kind of external USB-C to serial driver to install ?
Sorry I do not know the Mac but it probably requires a driver. The PC does and Linux needs you to be added to the dialout group.
I just made it work ! Needed to select the specific Nano ESP 32 board instead of default Arduino Nano.
So you don't have a classic Nano but a Nano ESP32?

I had a classic indeed and bought an ESP32 as I could bring the classic to work
