Brand new to Arduino and just bought an UNO Rev. 3. I own a Mac running Mojave. I downloaded and installed Arduino IDE version 2.2.1. I plugged the USB into my PowerMac, but no comm port is seen. I tried everything based on what I found on the forum, but nothing had worked. Wondering if my new UNO was defective, I tried it on my Windows 11 laptop (installed the software etc.) and it found it. So, why can I see it on Windows and not my Mac? I would like to use my Mac because it is where I do my electronics.
Thanks in advance!
