Every time that I open Network in System Preferences, a window pops up with the following message:

New Interface Detected

A new network interface has been detected:

Thunderbolt Bridge

Please verify that it is configured correctly, then press Apply to activate it.


What the heck is Thunderbolt Bridge & why did it appear all of a sudden & how do I prevent the window from popping up every time that I open Network in System Preferences?

I have a mini & there's nothing plugged into the Thunderbolt port. I did upgrade my router. I suppose that I have to disable it thru the router's webpage, right?

No, Thunderbolt Bridge is a software feature that lets two Macs talk to one another through the Thunderbolt port. Nothing to do with the router.

A quick note on the TB Bridge: If you have a newer Mac (2013, 2014) with Mavericks or Yosemite, the TB Bridge is automatically added to the network preference panel and pre-configured. It's listed right below WiFi, Ethernet, Bluetooth, depending on how you have that sequence arranged on your machine.

After I sent the post, I googled "Thunderbolt Bridge" & found out what you just stated. I logged onto my router & looked around & didn't see anything about Thunderbolt Bridge. One website stated that it appears if one has Mavericks installed because Mavericks supports it. The website also explained how to stop the nagging. I followed the directions & clicked on Network a few times & I wasn't nagged.

So, thank you for answering my question. That was simple!

I thought Thunderbolt Bridge was where pets go when they die. Or wait, maybe that's Rainbow Bridge. :)
