Hi, I'm using a MacBook Air with an M1 chip, and when I plug in my arduino uno, the serial ports are greyed out. I've seen that other people have had this problem but none of the solutions I saw worked for me. When I plug the card in the green lights is on and the orange light starts blinking. I've tried installing some FTDI drivers, selecting an other type of card, and I tried it on an other mac (with an intel chip), with the same result.
It's an official arduino, I got it in the arduino starter kit, and the usb cable is from there to.
I'm really new to arduino, so I don't know much about it and I just hope I'll be able to use my card soon.
