Speedify Uses a Tethered iPhone as Backup for Starlink on Mac to Keep You Online
This guide covers why a tethered iPhone is the most convenient backup for Starlink on Mac, how Speedify manages both internet connections, and how to set up Speedify in three steps.
Starlink disconnects all the time for ALL Starlink users. The Speedify Starlink Index report found that Starlink connections are down for an average of ~33 min per day. Plus, all Starlink dishes experience small drops and packet loss every 15 seconds, when the moving Starlink satellites hand off the connection to the next satellite overhead.
The best way to fix Starlink's connection drops is to combine your Starlink connection with another internet connection, such as 4G/5G cellular, cable, fiber, DSL, or another Starlink connection. Speedify makes this possible with channel bonding.
Most Starlink users already run a second connection.
From a sample of 6,228 Starlink users on Speedify, 71% ran at least one other internet connection while using Starlink. Cellular is the most common choice of backup connection.

Why Tether an iPhone for Use Alongside Starlink on Mac
Starlink and your iPhone’s 4G/5G cellular data use entirely separate infrastructure. Starlink connects through low-Earth-orbit satellites. Your iPhone’s cellular data connects through ground-based towers from your mobile carrier. An event that disrupts Starlink does not affect your iPhone’s cellular connection, and vice versa.
For Mac users who already own an iPhone, USB or Wi-Fi tethering turns the phone into an immediately available second internet connection. No additional hardware is required. The setup works with your existing mobile data plan. Connecting via USB also charges your iPhone while it provides the tethered connection.
With Speedify running on your Mac, both Starlink and the tethered iPhone carry your traffic simultaneously. If Starlink drops, Speedify continues routing traffic through your iPhone’s cellular connection without any interruption to your active sessions.
How Speedify Manages Starlink and a Tethered iPhone on Mac
Once your iPhone is tethered and your Mac is connected to Starlink Wi-Fi, Speedify detects both connections and begins monitoring them simultaneously. Speedify measures latency, packet loss, and available bandwidth on each path every few milliseconds.
When both connections are stable, Speedify distributes your traffic across both and delivers up to 95% of their combined upload and download capacity. When one connection degrades, Speedify moves all traffic to the healthy connection at the packet level. Calls, uploads, and streaming sessions are never dropped.
Speedify also encrypts all your internet traffic across both the Starlink and tethered iPhone connections, keeping your data protected on every path.
How to Combine Starlink and a Tethered iPhone on Mac with Speedify
Step 1: Enable Personal Hotspot on Your iPhone
On your iPhone, go to Settings > Personal Hotspot and turn on Allow Others to Join. To tether via USB, connect your iPhone to your Mac with a USB or USB-C cable and select Trust this Computer if prompted. Your Mac should detect the iPhone as a network interface automatically. To tether via Wi-Fi, connect your Mac to the iPhone’s hotspot network.
Step 2: Connect Your Mac to Starlink Wi-Fi
If tethering via USB, your built-in Wi-Fi is free to connect to Starlink. Go to System Settings > Wi-Fi on your Mac and connect to your Starlink network. Confirm both the Starlink Wi-Fi and the iPhone tether appear as active interfaces in System Settings > Network.
Step 3: Download and Run Speedify
Download Speedify and install it on your Mac. Speedify will detect both connections and begin bonding them immediately. No manual routing configuration is needed.
Speedify handles everything in the background from that point: combining both connections for faster upload and download speeds, monitoring for drops, failing over instantly, and encrypting all traffic.
Who Should Use Speedify with Starlink and a Tethered iPhone on Mac

Speedify Also Monitors Your Starlink Dish Status on Mac
Speedify displays real-time Starlink dish alerts in the app dashboard on your Mac. If your Starlink dish has a stuck actuator motor, a non-vertical mast, or a thermal throttle condition, Speedify shows the alert in the dashboard. Alerts appear when the condition has been active for at least 15 seconds and clear once resolved.
Speedify manages your internet connections and monitors your Starlink hardware from a single dashboard on Mac.
