How to use Lockdown Mode on your iPhone, iPad, and Mac
Apple is taking assertive action against the mercenary surveillance as a service industry with the introduction of Lockdown Mode, a highly secured usage state on Macs, iPhones and iPads, coming this fall. Here’s how it works.
How to use Lockdown Mode on your iPhone, iPad, and Mac
Lockdown Mode is an extreme protected state most people won’t need to put their devices in. It’s really aimed at what Apple calls the “small number” of users who may be targeted by of the most sophisticated digital threats, such as those from NSO Group and other private companies developing state-sponsored mercenary spyware. These can include civil rights advocates, politicians, journalists, and others targeted by authoritarian states.
When enabled, Lockdown Mode deeply restricts the attack surface that can be exploited by such attacks, but does also have a consequence on what you can do with your device.
What does Lockdown Mode do?
Turning on Lockdown Mode in iOS 16, iPadOS 16, and macOS Ventura applies the following protections to your device, Apple says:
- Messages: Most message attachment types other than images are blocked. Some features, like link previews, are disabled.
- Web browsing: Certain complex web technologies, like just-in-time (JIT) JavaScript compilation, are disabled unless the user excludes a trusted site from Lockdown Mode.
- Apple services: Incoming invitations and service requests, including FaceTime calls, are blocked if the user has not previously sent the initiator a call or request.
- Wired connections with a computer or accessory are blocked when iPhone is locked.
- Configuration profiles cannot be installed, and the device cannot enroll into mobile device management (MDM), while Lockdown Mode is turned on. NB: Devices with pre-existing MDM continue to be used.
The idea is that the mode protects your device against the attack vectors described above.
