Awesome,
Thank you, a lot of the time us noobs don't know what to search for.
I have removed the drivers and no longer get the kernal crash when plugging in a CH341 chip. I will have another look at them when I know a bit more about my Mac and how these things work. I maybe jumped in a little quickly.
Also, this is he link I used to get the drivers that caused me issues

I think it's the same one as you posted above, not too sure if that driver works with Sierra.
Thank you.
