macOS Sequoia Privacy Features You're Not Using
macOS Sequoia introduced several powerful privacy features that most users never enable. While Apple has made significant progress in giving users more control over their data, many of these tools remain hidden behind multiple menu layers or are simply not well explained.
This guide examines the most important privacy features in macOS Sequoia, explains how they actually work at a technical level, and helps you decide which ones are worth enabling for your specific threat model.
1. Lockdown Mode — The Nuclear Option
What it actually does
Lockdown Mode is Apple’s most aggressive privacy and security feature. When enabled, it disables or restricts many system capabilities that are commonly exploited by sophisticated attackers (especially state-sponsored ones).
Technical impact:
- Disables JavaScript JIT compilation in Safari
- Blocks most attachment types in Messages
- Prevents configuration profiles from being installed
- Disables FaceTime and certain camera features
Who should enable it: Journalists, activists, high-profile individuals, or anyone who believes they may be targeted by advanced persistent threats.
2. Hide My Email — Stop Email Tracking
How it works
Hide My Email (part of iCloud+) generates unique, random email addresses that forward to your real inbox. Every service you sign up for gets its own disposable address.
Privacy benefits:
- Prevents email-based tracking and profiling
- Makes it easy to identify which service leaked your email
- Allows instant disabling of any address without affecting others
Pro tip: Use it for every service you don’t fully trust. Combine with NetworkMonitor to also control what those services try to do on your network.
3. iCloud Private Relay — IP and DNS Protection
Technical explanation
Private Relay routes your Safari traffic through two separate relays (one operated by Apple, one by a third-party partner). This prevents websites and network providers from seeing both your IP address and the domains you visit at the same time.
Limitations: It only works in Safari and does not protect other applications. For system-wide protection, combine it with NetworkMonitor + NextDNS.
4. App Privacy Report — See What Apps Are Actually Doing
This often-overlooked feature shows you exactly which apps have accessed your camera, microphone, location, photos, and network in the last 7 days.
Why it matters: Many applications request far more permissions than they actually need. The App Privacy Report makes this visible and gives you the data to make informed decisions about which apps to keep or remove.
Our 2026 Recommendation
Here’s our practical advice for most users:
- Enable Lockdown Mode if you are in a high-risk category
- Use Hide My Email for every new service signup
- Turn on Private Relay if you use Safari heavily
- Check App Privacy Report monthly and act on suspicious activity
Remember: built-in Apple features are excellent, but they work best when combined with third-party tools like NetworkMonitor for complete outbound visibility.
