Screen Guard hides your personal apps and blocks private notifications when you mirror your screen or connect a display for a presentation.
Relax knowing your privacy stays completely safe.
In meetings or presentations, it's all too easy to accidentally expose sensitive apps—email drafts, personal chats, financial dashboards—or even private notifications—risking your privacy in an instant.
Privacy protection should work behind the scenes. We want every Mac user to feel secure during presentations—just mirror your screen or connect a display, and know you're covered.
Screen Guard springs into action on screen mirroring or unlock, instantly hiding your personal apps and blocking personal notifications with a full-screen overlay—so your privacy stays protected.
Screen Guard was born from our own frustration at narrowly avoiding embarrassing leaks when mirroring our screen or unlocking our Macs. As Mac enthusiasts, we built a tool that's invisible until you need it—then works instantly, reliably, and with zero friction. Today, we keep refining it so you can mirror, unlock, and work with total peace of mind.
Explore the latest enhancements in Screen Guard.
You can choose whether to block personal notifications during screen mirroring, external display use, and other presentation scenarios.
Screen Guard now shows a overlay on screen unlock to hide your chosen apps. Toggle it off anytime in settings.
Choose any weekday or set start/end times—e.g., Mon-Fri, 10:00-17:00—to keep Screen Guard active when you need it most.

Screen Guard supports macOS 14 and later.
We use a Shortcut to block pop-up messages when this feature is enabled. This Shortcut is triggered only when no Focus mode is active, helping prevent personal notifications from appearing during screen mirroring, external monitor connections, or other presentation scenarios—so you can stay focused.
To enable this feature, please follow the in-app guide to install the Shortcut. If you manually delete the Shortcut, Screen Guard will not take any action. To reinstall it, simply turn the feature off and back on—the installation guide will appear again.
This alert appears because the Block Pop-up Messages feature is enabled in your General Settings, but the required Shortcut is either not installed or has been deleted.
Click the “Select Apps button in the main window or drag an app from your /Applications folder into application. To remove one, just click the app you selected.
In the General settings, toggle the “When screen unlock” option on or off.
Yes—it appears by default whenever you mirror. To stop it from appearing:
Open Settings → general setting to pick weekdays and start/end times (e.g., Mon-Fri, 10:00-17:00) when Screen Guard remains active.
Every app uses resources, but Screen Guard is highly optimized with minimal memory footprint—its impact on performance and battery is virtually negligible.
No worries—once you've selected apps in Screen Guard, they're hidden automatically whenever you mirror your screen. You don't need to do anything extra.
Screen Guard runs entirely offline on your Mac and never records or transmits your private data.
