Can I combine two Ethernet connections on my Mac? You can, with Speedify

This article explains how to connect two Ethernet connections to your Mac and use Speedify to combine them for faster upload and download speeds and a more reliable internet connection.

What You'll Need

• A Mac with at least one built-in Ethernet port (or a USB-C (Universal Serial Bus Type-C) to Ethernet adapter)
• A USB to Ethernet adapter or Thunderbolt to Gigabit Ethernet adapter for the second connection
• Two separate Ethernet cables
• Access to two modems or routers
• Speedify installed on your Mac

Let's Get Started

Step 1

Connect your first Ethernet cable between your router or modem and the built-in Ethernet port on your Mac. In most cases, your Mac will connect to the internet automatically.

Step 2

Connect your USB to Ethernet adapter (or Thunderbolt to Gigabit Ethernet adapter) to an available port on your Mac, then run a second Ethernet cable from the adapter to your second modem, router, or wall plate.

Popular options include the Belkin USB-C to Gigabit Ethernet Adapter and the Apple Thunderbolt to Gigabit Ethernet Adapter.

To confirm both connections are recognized, go to System Preferences (or System Settings on macOS Ventura and later) > Network and look for both adapters listed on the left. Each should show a status of "Connected."

Step 3

Download and install Speedify if you haven't already. Once Speedify is running, it will automatically detect both of your Ethernet connections and combine them into a single, faster internet connection.
