How to enable lockdown mode on Mac

Lockdown mode is disabled under normal circumstances, and you’ll have to turn it on manually if you think you need its protection. This feature locks down many features on your Mac, so Messages, FaceTime, web browsing, and other apps don’t work exactly as you expect when they’re enabled. The trade-off is that with lockdown mode enabled, your Mac is less vulnerable to cyberattacks.

To enable lockdown mode on a Mac:

1. Open the Apple menu and click system settings.

2. click Privacy & Security.

3. Scroll down to the Lockdown mode section and click on it turn on.

4. Confirm with touch identification or click use password and enter your password.

5. click Power on and restart.

6. Your Mac will restart in lockdown mode.

   
   

What is Lockdown Mode on Mac?

Lockdown mode is a security feature that helps protect your computer from sophisticated cyber attacks. If you suspect that you have been the victim of a targeted attack or series of attacks, you can enable this feature to protect your system and data.

When you enable lockdown mode, you must expect the following limitations:

• Messages: Some features are disabled, including link previews. Most types of message attachments are also automatically blocked, with the exception of simple images.
• surf the Internet: Some websites do not work properly or do not load at all because this mode blocks some critical web technologies.
• Apple Services: Incoming FaceTime calls and other invitations and requests are automatically blocked if you haven’t previously sent that person a call or request.
• configuration profiles: New profiles can’t be installed, so you can’t enter the Mac Beta Program or install a profile for your school or work while lockdown mode is on.
• Additional Restrictions: Apple will add additional restrictions and adjust how lockdown mode works over time to address new threats and provide additional protection.

Who needs to use lockdown mode?

Most users will never need lockdown mode as it is designed to protect against the kind of sophisticated, targeted attacks that few users are exposed to.

If you work in a sensitive industry or government position, are a journalist, or are otherwise likely to have your devices targeted by hostile actors, Lockdown mode can pre-emptively protect your device from attacks. If you suspect that you have been attacked, you can also activate this mode at any time.
