Quick answer: choose the right sharing mode
If your meeting only needs one browser, slide deck, document, or coding window, share that window instead of the whole desktop. This creates the smallest exposure surface because other open apps are not part of the shared feed.
Entire-screen sharing is useful when you need to move between apps. Before you start, learn how to blur your screen on Mac before a call, enable Veil, select the app that should remain readable, and verify that background chats, notes, email, and browser windows are blurred. Veil is a visual privacy layer rather than a security boundary, so you should still close highly sensitive material.
Single-window sharing vs entire-screen sharing
| Sharing mode | Best for | Privacy trade-off |
|---|---|---|
| One window or browser tab | A focused presentation that stays in one app | Lowest risk because unrelated apps are outside the shared feed |
| Entire screen | Demos that move between several apps | Everything visible can enter the feed, so preparation and a privacy overlay matter |
| Selected screen on a multi-monitor Mac | Keeping meeting controls on another display | Only the chosen display is shared, but private windows on that display still need protection |
Before screen sharing: a seven-step Mac privacy checklist
- Choose what viewers need to see. Use a single-window share when the presentation can remain in one app.
- Close highly sensitive material. A blur reduces readability, but closing confidential files is safer.
- Turn on macOS Focus. Veil does not hide notification banners, so suppress them separately.
- Check Veil permissions. Confirm that Accessibility permission is enabled using the Veil permission guide.
- Select the clear app. Choose your Cover App or use the active-window workflow so the presentation remains readable.
- Enable Veil before sharing. Do not wait until the meeting is already seeing your desktop.
- Preview the result. Use the meeting app's preview and confirm that the intended app is clear while other windows are blurred.
How to hide windows in Zoom, Microsoft Teams, and Google Meet
Zoom on Mac
Zoom can share an entire desktop, a specific application, or a selected portion of the screen. Its official screen sharing guide explains these choices. Select one application when possible; for an entire-desktop demo, turn on Veil first and keep your presentation app clear.
Microsoft Teams on Mac
Microsoft Teams lets you choose a screen or an individual window, as described in Microsoft's screen sharing instructions. Teams' camera background blur affects your video, not the windows on your desktop. Use a window share for one-app presentations or Veil when the workflow requires the whole screen. If viewers report a soft image, follow the Teams screen-sharing quality checks for Mac.
Google Meet on Mac
Google Meet distinguishes between a browser tab, a window, and the desktop. Google's screen sharing guidance notes that features vary by sharing mode. A tab or window is the narrowest choice; use the entire screen only when the audience needs to follow you across apps.
During the screen share
Keep the app you want viewers to read in focus. If you intentionally switch to another app, confirm that it is now the clear window before discussing its contents. Avoid opening private material simply because it is blurred—the meeting should never depend on blur as the only protection for highly confidential data.
Use Peek when you need a brief full-desktop reveal, then return to the protected state. If the meeting changes from a single-app presentation to a multi-app demo, stop sharing for a moment and verify the new setup before resuming.
After the meeting
- Stop sharing before turning off Veil or rearranging private windows.
- Turn Veil off when the presentation is finished.
- Clear or change the Cover App if your next task uses a different window.
- Restore your normal Focus settings after the call.
What Veil protects—and what it does not
Veil helps hide readable content in background windows while keeping one selected or active app clear. It is useful for private chats, internal notes, browser tabs, email, and documents that could otherwise remain visible during an entire-screen share.
Veil does not hide macOS notifications, remove sensitive files from your computer, prevent screenshots, or replace access controls. Read the macOS screen sharing privacy app guide for the product workflow, follow the step-by-step guide to blur background windows while screen sharing, or explore the broader background-window blur guide.
Frequently asked questions
How can I hide other windows while screen sharing on Mac?
Share one application window when possible. If you need to share the entire screen, turn on Veil first, keep your presentation app active, and use macOS Focus to suppress notifications. Preview the shared feed before showing it to participants.
Is sharing one window safer than sharing the entire screen?
Yes. Sharing one window limits the meeting to that application. Entire-screen sharing is more flexible, but it can expose other apps whenever you switch tasks, move windows, or open a notification.
Can I hide Slack, Messages, or email while presenting?
Veil can blur those apps when they are background windows and another app remains clear. For a focused workflow, follow the guide to hide chat windows during meetings.
Does Veil hide Mac notifications?
No. Veil blurs background windows, not notification banners. Turn on macOS Focus or Do Not Disturb before the call; the notification privacy guide explains the difference.
Does this work with Zoom, Microsoft Teams, and Google Meet?
Yes. Veil works at the Mac desktop level, so the same preparation workflow applies before sharing through Zoom, Microsoft Teams, Google Meet, or a screen-recording app.
