Mac screen sharing privacy
Hide notifications when screen sharing on Mac in 6 steps.
Use Focus, share one window, protect sensitive apps, enable Presenting Mode, and run a test before the meeting or recording starts.
Step by step
Run this checklist before sharing your Mac screen.
The first two steps use macOS and the meeting app. The privacy utility adds protected apps and presentation controls, but it cannot choose the correct shared source for you.
Turn on Focus before the call. In System Settings > Notifications, review whether notifications are allowed while mirroring or sharing the display; then open Privacy & Security to confirm which meeting apps can record the screen and system audio. Apple documents both notification settings and screen recording permission.
Share one application window when the meeting app allows it. Sharing an entire display makes unrelated windows, menu-bar activity, and desktop content easier to expose.
Close unrelated chat, email, finance, client, and internal-tool windows. In Anti-spy screen Lite, mark the apps that should be hidden when privacy protection triggers.
Before the meeting, use Presenting Mode and a Privacy Color Block where needed to reduce exposure from sensitive windows or private screen regions.
Start a test call, confirm the exact source being shared, open a harmless notification, and verify that private apps and screen regions remain hidden.
End screen sharing before reopening private apps. Confirm the meeting app is no longer recording, then restore hidden windows deliberately.
Risk checklist
Know which control addresses each privacy risk.
Screen sharing, mirroring, and shoulder surfing are different risks. Use the meeting app for the shared source, macOS for recording permission, and the privacy utility for selected app hiding, Presenting Mode, color blocks, and nearby-face protection.
Choose the correct window or display and verify the live preview before other participants join.
Control which apps may record the screen and system audio in Privacy & Security settings.
The free listing documents protected apps, Presentation Mode, Privacy Color Blocks, mirroring-aware hiding, and on-device face detection.
Nearby-face detection addresses shoulder surfing. It does not confirm that the meeting app is sharing the intended window or display.
Current App Store facts
Start with the free version before a real meeting.
The current US listings make Lite the lower-friction way to test camera placement, protected-app behavior, and presentation controls on your own Mac.
Anti-spy screen Lite is currently free to download. The full Anti-spy screen listing is a $2.99 one-time purchase; prices can vary by storefront.
Both current listings require macOS 13.0 or later.
The Lite listing says the camera feed stays on the Mac, nothing is recorded or uploaded, and the app requires no account or internet connection.
Lighting, camera angle, the selected face threshold, and the meeting app's shared source all affect the real workflow.
Screen privacy FAQ
Common Mac privacy questions.
How do I hide notifications while screen sharing on Mac?
Turn on Focus before the call, review macOS Notifications settings for mirroring or display sharing, and send a harmless test notification before participants join.
Which Anti-spy screen features support screen privacy?
The current listings document local face detection, selected app hiding, a draggable Privacy Block, and Presenting Mode for reducing background pop-up exposure.
What is the main risk during screen sharing?
Private windows, notifications, documents, or protected work can be exposed when the wrong app or desktop area is shared.
Does this replace careful meeting setup?
No. It supports a privacy workflow. Users should still check the meeting app, shared screen source, and protected apps before presenting.
Where do I change Mac screen recording permission?
Open System Settings, choose Privacy and Security, then open Screen and System Audio Recording to review which apps may record the Mac screen and audio.
Does face detection guarantee screen sharing privacy?
No. Face detection can respond to another person near the Mac, but it cannot verify which window or display the meeting app is sharing. Always confirm the shared source and preview.
