What is Lockdown Mode and how to use it

One of Apple’s major focuses in recent versions of all of its operating systems has been privacy. And macOS Ventura was no different. One of the new features it introduced was Lockdown Mode. But what is Lockdown Mode and why should you care about it? And, just as importantly, how do you use it? We’ll explain everything.

What is Lockdown Mode?

Lockdown Mode is a feature on Mac, iPhone, iPad, and Apple Watch that is designed to protect against highly targeted attacks using spyware and other malware. It causes several Apple apps and services to behave differently, including in the way that images and files are downloaded and location is shared. Apple says Lockdown Mode is designed for ‘the very few individuals who, because of who they are or what they do, may be personally targeted by some of the most sophisticated digital threats.’ From that description, you can see that Lockdown Mode is a highly specialized feature because most of us don’t fall into that category, and so don’t need Lockdown Mode. But for those who do, it could be invaluable.

How to protect your Mac from security threats

Lockdown Mode is an extreme measure to protect your Mac against security threats and is designed only for those most at risk. But there are plenty of things that the rest of us can do to improve the security of our Macs. One of those is to scan for malware regularly. Malware comes in lots of different forms, and avoiding it isn’t easy. CleanMyMac X’s Malware Removal module can help. It scans your Mac and compares what it finds against a database of known malware. If it finds anything suspicious, it will alert you and allow you to remove it easily. And you can run it manually on an ad-hoc basis or set it to run in the background to scan for threats in real time. You can download CleanMyMac X for free here and try it for yourself.

What does Lockdown Mode do?

In essence, Lockdown Mode places greater restrictions on how apps receive files from elsewhere and how they share personal data. Here’s the list:

• In Messages, most attachments are blocked, with the exception of certain images, videos, and audio. Other features like links and link previews cannot be used.
• Images and web fonts may not be displayed when you browse the web, and some web technologies are blocked, meaning websites might load more slowly.
• Incoming FaceTime calls from people who are not in your Contacts will be blocked, and you won’t be able to use Live Photos or SharePlay.
• When you share photos in the Photos app, the location data is removed. You are removed from shared albums and can’t receive invitations for shared albums.
• You need to unlock your Mac and give specific permission to connect it to an iPhone, iPad, or another device.
• Your Mac won’t automatically connect to unsecure Wi-Fi networks, and if you are connected to an unsecure network when you turn Lockdown Mode on, you will be disconnected.
• You won’t be able to install configuration profiles or enroll in mobile device management programs.

Lockdown Mode, then, severely restricts the way in which your Mac works. And if you enable it on your iPhone or iPad, it will restrict how you use those, too. It’s a trade-off between maximizing your security and minimizing the use of all the features you currently enjoy. If you feel you’re at risk from a targeted security threat, it’s up to you to decide whether that trade-off is worth it.
