How to Connect a Thunderbolt Apple Display to Newer Macs with USB-C

Apple's Thunderbolt Display remains a reliable and high-quality external monitor for many users. However, with the evolution of Mac models and the introduction of USB-C/Thunderbolt 3 ports, connecting older Thunderbolt displays to newer Macs can pose some challenges—especially if the built-in Thunderbolt cable on the Apple Display is faulty. This guide will walk you through the steps to connect your Thunderbolt Display to a newer Mac using alternative methods and adapters.

What You’ll Need

To connect your Thunderbolt Display to a USB-C/Thunderbolt 3-enabled Mac, you’ll need the following items:

1. Apple Thunderbolt Display (Model Number: A1407)

2. Thunderbolt to USB-C Adapter (e.g., Apple Thunderbolt 3 to Thunderbolt 2 Adapter)

3. Thunderbolt Cable (if the built-in cable is faulty)

4. A newer Mac with USB-C/Thunderbolt 3 ports

Step-by-Step Guide

 Using the Built-In Cable

If the built-in Thunderbolt cable of your Apple Display is functioning properly, follow these steps:

1. Plug the built-in Thunderbolt cable of the display into the Thunderbolt to USB-C adapter.

2. Connect the USB-C end of the adapter to one of your Mac’s USB-C/Thunderbolt 3 ports.

3. Ensure the display is powered on and your Mac detects the external monitor automatically.

Please Note: The Apple Thunderbolt Adapter only works with Thunderbolt Display. It does not support Apple Cinema Display or other mini Displayport connections.

Using the Thunderbolt Port on the Back of the Display (Faulty Cable)

If the built-in Thunderbolt cable is faulty or unreliable, follow these steps:

1. Locate the Thunderbolt Port: On the back of your Thunderbolt Display, find the Thunderbolt port.

2. Connect a Separate Thunderbolt Cable: Use a compatible Thunderbolt cable to connect the display’s Thunderbolt port to the adapter.

   • Insert one end of the Thunderbolt cable into the Thunderbolt port on the back of the display.

   • Connect the other end of the cable to the Thunderbolt to USB-C adapter.

3. Attach the Adapter to Your Mac: Plug the USB-C end of the adapter into one of your Mac’s USB-C/Thunderbolt 3 ports.

4. Power On the Display: Ensure the display is connected to power and turned on. Your Mac should detect the display automatically.

5. Test the Setup: Verify that the display is working correctly. If it doesn’t appear, check the connections and cables.

Troubleshooting Tips

1. Ensure Compatibility: Verify that your Mac supports Thunderbolt displays via the Thunderbolt to USB-C adapter. Most newer Macs with Thunderbolt 3 ports should support this configuration.

2. Check Cable and Adapter Quality: Use genuine Apple adapters and high-quality Thunderbolt cables to avoid connectivity issues.

3. Update macOS: Ensure your Mac is running the latest version of macOS. Compatibility with certain adapters and displays can improve with software updates.

4. Reset Display Settings: If the display isn’t recognized, reset your Mac’s System Management Controller (SMC) and NVRAM/PRAM.
   
   

Why Use the Thunderbolt Port on the Back of the Display?

The Thunderbolt port on the back of the Apple Display is a convenient alternative if the built-in cable is damaged or non-functional. It allows you to connect the display to your Mac without replacing the entire built-in cable assembly, saving time and cost.

Conclusion

Connecting an Apple Thunderbolt Display to a newer Mac is straightforward with the right accessories. By utilizing the Thunderbolt port on the back of the display and a combination of a Thunderbolt cable and a Thunderbolt to USB-C adapter, you can bypass a faulty built-in cable and continue to enjoy the exceptional performance of your Thunderbolt Display.

Ensure you have the correct adapters and cables, and don’t forget to keep your macOS updated for the best compatibility. With these steps, your Apple Thunderbolt Display will remain a valuable tool in your workspace setup for years to come.
