Trying out my new Arduino Nano (Elegoo) and there are no serial ports showing up so I cannot upload anything to it. Is this something to do with CH340? I just tried it on a windows laptop and it worked fine????

I'm having the same issue with a generic / clone I just purchased. It works fine on a Windows 10 laptop so there's nothing amiss with the USB cable.
ls /dev/tty.* returns - /dev/tty.Bluetooth-Incoming-Port /dev/tty.MxxxxxxxiPodTouch-Wirel
Seems I am missing /dev/tty.Serial* and /dev/cu.Serial* according to what I am seeing on forums so I am suspecting there's a step I missed when installing the Arduino IDE.
It's a very old MacBook Pro (Late 2011) running OS X Sierra 10.12.6
Can anyone point me in the right direction?
Answered my own question and maybe the original after rereading the original post and realizing what we had in common was the board is CH340 based.
A quick search led me to this page:-

Where I found a link to this driver:-

That worked!
I tried a package 1.5 for Mac no difference. Thought I try that one as it was released 12 days ago, Might move it at try the older one!
Looked for the usb.kext to delete and it wasn't there only a usbserial.kext! Unsure how to delete the 1.5 package in order to install 1.4. The final step ask me to type in (sudo nvram boot-args="kext-dev-mode=1") in the terminal but it returned an error and still cannot get my Nano to work. HELP!!!
