Yun won't show up as a Port in IDE

My Arduino Yun is not showing up in the Port menu of the IDE. THe MacBook is on the same Wifi router as the Yun and has previously shown up on the Port menu however I upgraded to a new laptop last week. I'm no sure how to troubleshoot this.

I am able to use a browser to connect to the Yun's and log in just fine. Any ideas? Thanks.

I had a similar thing happen, my Arduino 1.5.5 was stuck at an old IP and I could not switch , what I did to solve it was:

Pick a different board pick a different port, like any serial port close the program start the program pick the Arduino Yun this time I could pick the new IP
