Can I add a status icon for thunderbolt ethernet to the menu bar? (Mavericks) As the title suggests, I'm using a mac book pro with os x 10.9.2 and I connect to the network through the ethernet adapter thunderbolt.

Is there a way to get a reference icon in the menu bar, as is the case for the wifi?

I'd prefer not to use applications such as iStatsMenu or similar ..
Did you try this from: https://discussions.apple.com/thread/5598818

  Accordingly, I went into /System/Library/CoreServices/MenuExtras/ then double clicked on WWAN.menu for cable broadband. I think for DSL you'll need to click on PPPoE.menu.


Give it a try, otherwise you probably need third party apps like iStatsMenu
