Serial monitor causes my computer to restart any fixes?

When I upload a scratch sometimes my Mac PC restarts. Also when I open serial monitor my computer restarts.

I’m using a Chinese nano and this started when I downloaded the usb driver needed to recognize the board.

This did not happen when I used the blink sketch as a test. Any ideas?

I think this is a problem with the wrong version of the drivers. The behavior of MacOS w/regards to CH340G drivers has changed several times in the past few versions of MacOS, as Apple keeps changing things, and then the old drivers cause crashes.

I don’t have a mac so I don’t know the details. Last I heard though, the most recent version of MacOS didn’t need drivers, and installing the drivers meant for older versions of MacOS caused problems.
