Do you want to know why the thunderbolt bridge is not connected? Okay! You don’t need to worry. You are in the right place, and here we’ll answer your confusion. 

Are you facing some problem with the thunderbolt bridge not being connected and a little bit confused? Also, if you’d want some guidance. You’ve come to the right place. Because this article is specifically for you, keep reading and don’t become confused now and in the future.

Apple’s new MacBook Pro models, which feature Thunderbolt, are the most recent connection technology. The Thunderbolt interface allows files to be shared between Macs, starting with Mavericks OS X (Version 10.9). 

Transmitting data through a Thunderbolt cable is substantially quicker than using an existing Wi-Fi or Ethernet connection to move files between Macs. Ethernet, Wi-Fi, and Thunderbolt are all examples of these technologies.

Before connecting Luna, you must establish a Thunderbolt bridge between your Macs. Use a Thunderbolt cable instead of a conventional USB-C cable (such as the charging one that comes with your Mac).

To open Network Preferences on your primary Mac, click on the Wi-Fi sign in your menu bar and pick “Open Network Preferences” in System Preferences. Set IPv4 Configuration to “Using DHCP” in the Thunderbolt Bridge option on the left.

When your primary Mac recognizes that your secondary Mac is connected, an IP Address will appear in the IP Address section. The “Self-Assigned IP” label will appear next to the connection status in the left-side menu panel, as will a yellow dot.

Additional Troubleshooting with Thunderbolt Connections

  • The Thunderbolt cable must be attached to each Mac, router, or access point to function correctly.
  • Restart your Macs or router, or modem.
  • Make sure your Thunderbolt cable is compatible before using it.

Examine the Thunderbolt connection between your device and Mac

This means Thunderbolt devices may not be appropriately linked to your computer, which might cause problems with their performance. It’s possible that a Thunderbolt device isn’t correctly connected to your computer if it’s not working.

Ensure your Mac is up to date and connect a Thunderbolt device to your Mac’s Thunderbolt port. Restart your Mac if you can’t utilize the device you want to use. A problem with your Mac’s USB port may necessitate a repair. See, You may learn how to fix or service your Mac on this page.

Remove all devices and cables from your Mac and connect the device to your computer directly with the cord that came with it. There may be an issue with one of the other devices if the device is working well. You can try reconnecting each of the other devices and wires one by one to your Mac. For further troubleshooting instructions, see your device’s manual.

Examine the Thunderbolt connection to the Ethernet on your device

Open Network Preferences on your primary Mac by heading to System Preferences > Network or clicking on the Wi-Fi sign in your Mac’s top menu bar and selecting “Open Network Preferences.” Select USB/LAN from the left-side menu.

When your devices are linked through Ethernet, the Status changes to Connected, and the USB/LAN option on the left side menu panel shows “Connected” or “Self-Assigned IP.”

Additional Troubleshooting for Ethernet Connections

  • Connect the Ethernet cable to both Macs, routers, and access points to ensure it works correctly.
  • Your router or modem should be restarted, or a new network location should be selected on your Macs.

How do I activate the Thunderbolt Bridge? 

To access Network Preferences on your primary Mac, go to System Preferences > Network or pick “Open Network Preferences” from the Wi-Fi menu bar icon. Set IPv4 Configuration to “Using DHCP” in the Thunderbolt Bridge option on the left.

How do I activate the Thunderbolt bridge on my MacBook Pro? 

Thunderbolt cables must be plugged into Thunderbolt ports on both machines. Choose the Apple menu > System Preferences, and then click on Network in the window that appears. Go to the list on the left and pick Thunderbolt Bridge.

What is Thunderbolt Bridge on Mac? 

Thunderbolt is a feature of the Mavericks OS X (Version 10.9) that allows data to be exchanged between Macs via the Thunderbolt port. File transmission using a Thunderbolt cable is significantly quicker than over Wi-Fi or Ethernet, making it ideal for moving files from an older Mac to a newer one.

Why is my Thunderbolt not working?

Unplug the Thunderbolt cable from the computer you are using. A few seconds later, reconnect the cable. When everything else fails, reboot your computer.

Final words

Hopefully! Using any of the methods outlined in this article can benefit you in many ways. Or, if you’re having difficulties, try to fix them. If Luna identifies an active Thunderbolt connection between your Macs, it should connect automatically. It is possible to change Luna’s settings so that it exclusively connects over Thunderbolt rather than Wi-Fi.
