#58943 I also had some issues with the nodemcu and a iMac.
With arduino software installed I still had not the right port under the tool section in the arduino menu.
For me it was installing "china drivers" restart the computer and then it was listed.

The china drivers I used was here: http://kig.re/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html
