If you own two Macs and want to take advantage of the high-speed connection provided by Thunderbolt, you’ve come to the right place. This comprehensive guide will walk you through the steps required to connect two Macs using Thunderbolt, highlighting the benefits and possibilities that come with it.
Understanding Thunderbolt Technology
Before diving into the connection process, it’s essential to understand what Thunderbolt technology is and why it’s beneficial for connecting two Macs. Thunderbolt, developed by Intel in collaboration with Apple, is a hardware interface that combines data, video, and power in a single connection. Here are some key features of Thunderbolt:
- High-Speed Data Transfer: Thunderbolt can transfer data up to 40 Gbps, making it significantly faster than traditional USB connections.
- Multiple Connections: With Thunderbolt, you can daisy-chain up to six devices on a single port.
The latest versions of Thunderbolt, including Thunderbolt 3 and Thunderbolt 4, use a USB-C connector, making it more versatile. Most recent Macs come equipped with Thunderbolt ports, making it easier than ever to connect and share resources.
Prerequisites for Connection
Before you start connecting your Macs, there are several prerequisites you should take care of:
1. Check Thunderbolt Compatibility
Make sure both Macs support Thunderbolt. You can check this by looking at the ports on each device. Macs compatible with Thunderbolt usually have ports identified by a lightning bolt icon. If your Macs are from 2011 or newer, they should support some version of Thunderbolt.
2. Thunderbolt Cable
To connect the two Macs, you will need a Thunderbolt cable, which has the necessary specifications for high-speed data transfer. If you’re using Thunderbolt 3, ensure that you have a compatible USB-C cable that supports Thunderbolt speeds.
3. Prepare the Macs
Update both Macs to the latest macOS version to ensure compatibility and security. This can be done through the System Preferences > Software Update.

What is Thunderbolt and how does it work for connecting Macs?
Thunderbolt is a hardware interface that allows the connection of peripheral devices to a computer. It combines data, video, audio, and power in a single connection and supports daisy chaining, meaning you can connect multiple devices through a single Thunderbolt port. For Mac users, Thunderbolt provides a high-speed connection that is ideal for tasks such as file transfers, external displays, and other high-bandwidth applications.
When connecting two Macs using Thunderbolt, you enable direct data transfer between the machines. This is accomplished using a Thunderbolt cable to create a peer-to-peer network, which is significantly faster than traditional USB connections. This setup is particularly useful for quickly transferring large files, accessing data on one Mac from another, or sharing displays.
What cables do I need to connect two Macs via Thunderbolt?
To connect two Macs via Thunderbolt, you will need a Thunderbolt cable. Depending on the models of your Macs, you may require either a Thunderbolt 1/2 cable or a Thunderbolt 3 cable. Thunderbolt 3 uses the USB-C connector, while Thunderbolt 1 and 2 use the Mini DisplayPort connector. It’s essential to ensure that both Macs have compatible Thunderbolt ports for proper connectivity.
Before purchasing a cable, check the specifications of your Macs to determine the version of Thunderbolt they support. Remember that while Thunderbolt cables are designed for high-speed connections, using a compatible cable will ensure that you achieve optimal transfer speeds. If you have a mix of Thunderbolt versions, adapters may be needed to connect them effectively.
How can I set up the connection between two Macs?
Setting up a connection between two Macs via Thunderbolt is straightforward. First, ensure both Macs are powered on and have the required Thunderbolt cables connected. Once connected, the next step is to open the Finder application on either Mac. You should see the other Mac appear in the sidebar under “Locations.” Click on it to establish a connection.
If you want to transfer files, you can use features like Target Disk Mode, which allows one Mac to act as an external drive for the other. To enter Target Disk Mode, restart the Mac you want to share and hold down the ‘T’ key during boot-up. The Mac will boot into Target Disk Mode, and its hard drive should appear on the other Mac’s desktop, making file transfers very simple.
What are some advantages of using Thunderbolt for file transfers?
One of the main advantages of using Thunderbolt for file transfers between two Macs is the high-speed data transfer rates it offers. Thunderbolt 3, for instance, can achieve speeds up to 40 Gbps, making it suitable for transferring large files, such as high-definition videos or extensive datasets, in a fraction of the time required by USB connections. This speed also improves productivity, as users can move files quickly without long wait times.
Additionally, Thunderbolt supports a variety of protocols, including PCI Express and DisplayPort, allowing you to use the connection for multiple functions simultaneously. This means you can transfer data while also connecting external displays or other peripherals. The versatility of Thunderbolt connections makes them a preferred choice for creative professionals and anyone who regularly handles high-bandwidth tasks.
Are there any limitations to connecting two Macs via Thunderbolt?
While Thunderbolt provides many benefits, there are some limitations to consider when connecting two Macs. One key limitation is that both Macs need to have compatible Thunderbolt ports. If one Mac has an outdated version of Thunderbolt, you may not achieve the optimal speeds, or they may not connect at all without an appropriate adapter. Therefore, it’s essential to verify port compatibility before attempting a connection.
Another limitation is that although Thunderbolt allows for direct file sharing, it is not as straightforward as using network connections for some tasks. For instance, if you are trying to share internet connections or use both Macs in a collaborative environment, it might require additional networking configurations. Understanding these limitations can help you prepare for the best way to utilize your Thunderbolt connection effectively.
Can I connect additional devices through Thunderbolt when connecting two Macs?
Yes, one of the great features of Thunderbolt is its ability to daisy chain multiple devices. If you are connecting two Macs with Thunderbolt and want to connect additional peripherals, you can do so easily using a Thunderbolt hub or daisy chaining. For example, you can connect a Thunderbolt display or external storage device to one of the Macs or the Thunderbolt port on the connection between them.
However, when daisy chaining devices, be aware that the overall performance may vary depending on the number of devices connected and the workload placed on them. The total bandwidth is shared among all connected devices, so it’s crucial to consider the data requirements of each device. Nonetheless, this flexibility makes Thunderbolt a robust option for users needing multiple connections.
