Arduino IDE on MacBook Pro, macOS High Sierra 10.13.4 doesn't show serial ports.

Can anyone help to resolve the issue?

Thanks

What kind of board do you have? If you're using "third-party" derivatives (like many Nanos), you'll need to install 3rd party drivers. (ie search for CH340)

Thanks. So far I found this one https://kig.re/downloads/CH341SER_MAC.ZIP
but not succeed yet :frowning:
After installation I type in terminal ‘ls /dev/tty*’ and I can't see it.

Try the one directly from wch.cn: http://www.wch.cn/product/CH340.html (the CH341SER_MAC.ZIP file)
I was somewhat surprised when it installed and worked painlessly on the new high-sierra hackintosh I've been putting together...

Thank you for help. I installed it directrly from wch.cn
Unfortunately it's the same result: still nothing seen in terminal neither in Arduino IDE.
