The Nano is Crashing My Mac PLEASE HELP

so I have the Nano for a school project. I've been messing around with it and downloaded an old driver for it mistakenly. now every time i plug the usb into my macbook pro it restarts the laptop. I don't know much about this stuff so im pretty lost. please help cheers, greg

So I suspect you got a Chinese clone with either Prolific, CH340g or FTDI clone on board as USB/serial communication chip.

If you still know what you did install: - de-install the bad driver - google for the latest driver - install and you should be on the road again
