How to Lock your Mac Screen with an iPhone

by Kaushal

While Apple Watch does allow you to unlock your Mac without entering the password, there is no way to remotely lock your Mac. One workaround to this problem is to use third-party apps such as MacID and NearLock. But if you are looking for a native way to remotely lock your Mac using your iPhone, you can use apps such as Shortcutify. It uses Siri Shortcuts to set everything up, so you can actually ask Siri on iPhone to lock and unlock your Mac. Before we begin, there are a few steps to set up everything but it would only take a few minutes and I’ll keep the description as thorough as possible.

How to Lock your Mac Screen with an iPhone

Step 1. Install Shortcutify on your iPhone

First, install the Shortcutify app on your iPhone. Also, make sure you’re running the latest iOS and have the Shortcuts app is installed on your iPhone. Once you have the apps installed and ready open Shortcutify.

Step 2. Find your Mac’s local IP Address

This method only works on local Wifi so make sure your Mac is connected to the Wifi. If you don’t know the IP address of your Mac, go to System Preferences> Network> Your IP Address. Note down the IP Address, we’ll need it later.

As the shortcut would essentially log in to your computer remotely, you would have to enable Remote Login feature on your Mac first. To do this, go to System Preferences> Sharing> Enable Remote Login.

Unlock your Mac with iPhone

If you want to set up a Siri Shortcut to unlock your Mac with the iPhone, doing it is just as simple. You just need to create another shortcut and add macOS: Wake and Log In action to your shortcut. It would require your password, so add it in the text field and save your shortcut. You would be able to unlock your Mac by simply tapping the shortcut or asking Siri to run the unlock Shortcut.
