How to Combine Ethernet and Tethered iPhone on Mac

With Speedify, it’s easy to combine your wired Ethernet connection with the connection from your tethered iPhone on your Mac. This allows your Mac to use the cellular connection from your iPhone as an additional internet source.

In this article, we are going to walk you through how to do it. 

Step 1: First, connect to your Ethernet connection. Some older Macs come equipped with an Ethernet port, but most will require you to use either a Thunderbolt-to-Ethernet or USB-to-Ethernet adapter. Once you have connected your Ethernet cable to your laptop, plug the other end into your modem or router.

In most cases, you will connect to the internet automatically. If not, proceed as follows.

Step 2: Click the Apple menu and select System Preferences; then click Network.

Step 3: Select the Ethernet connection from the list on the left, keeping in mind that it may be named according to the adapter you are using.

Step 4: Click the Configure IPv4 pop-up menu and choose your ISP’s recommended configuration method. You can read more about these configurations here.

Step 5: Under Advanced, click DNS. Then add a DNS server using the + button. Enter the IP address of your ISP’s DNS server.

Step 6: Click Apply to activate these settings. 

Step 7: Now it's time to connect to your tethered iPhone. First, turn on your iPhone’s Personal Hotspot. To do this, open the Settings app and tap Personal Hotspot. Then toggle the switch on.

Step 8: Ensure that you have the latest version of iTunes installed on your computer.

Step 9: Connect (or “tether”) your iPhone to you Mac using a USB cable. When you do this, iTunes should immediately recognize your device. If an alert appears asking if you “Trust this Computer,” tap Trust.

If you prefer, you can also tether your iPhone to your Mac using Bluetooth. Learn how  here. Keep in mind that Bluetooth is not typically the optimal method for tethering: it is limited to 1 Mbps (Bluetooth 4) or 2 Mbps (Bluetooth 5). If you have fast LTE speeds on your phone, you might get better results with the method described above.

Step 10: Now it’s time to get you connected! Open System Preferences on your Mac. Then click Network and select iPhone USB. If you don’t see it, click to add it. Since you are already connected to Ethernet, your Personal Hotspot connection might not activate until you uncheck “Disable unless needed” under Status.

Step 11: Combine connections by turning on Speedify. When you launch Speedify, the software automatically detects the Ethernet and tethered phone connections. You will see them each contained in a Connection Bubble near the top of the Dashboard.

And presto! You’re combining connections with the magic of Channel Bonding for improved speed, reliability, and security. You are now free to go forth and browse the internet, stream videos, and use your apps as you normally would.
