I am new to Arduino and I have ran into an issue. When I first tried to plug the arduino nano (after market, from ebay) into my computer (Macbook pro M1), nothing happened. Then I downloaded the cp210xVCP Driver. After that, when I plugged in the nano, the /dev/cu.usbserial- 1110 appeared. But when I try to get board info noting happens. It's like the computer recognize there is something, but does not know what. I believe Arduino is not fully compatible for M1 macbooks, but is there something I can do to fix this?

    Have you tried uploading a sketch now your board is detected by the OS?

    My Arduino clones don't give any Board Info either, so this might be not related to just M1 Macbooks... Commented Jul 16, 2021 at 10:16

Majenko and Python Schlange have the right of it I think. This is a common and well documented phenomenon. Check out the comments on the Arduino forum by the arduino team which explain PIDS and VIDS on USB equipment and why the clones appear differently. It shouldn’t (all going according to plan) make a difference other than the board information not being present as you’ve noted. That’s why Majenko is suggesting you go ahead and upload a sketch. The Blink example sketch is frequently used for this as a first board test when you receive something new.
