How to hide private apps in Microsoft Teams on Mac

Choose a Teams window share or a filtered window

Microsoft's current Teams instructions distinguish between sharing a screen and selecting a window or file. If one prepared app contains everything the audience needs, choose that window in the Share tray. Other apps remain outside that source, and ScreenVeil is not required.

A multi-app walkthrough is different. You may need a browser, spreadsheet and prototype in public while Slack, Mail or notes stay available privately. ScreenVeil creates a separate macOS window named Privacy Screen that leaves out the whole apps or windows you mark private. Teams only receives that filtering when you explicitly share Privacy Screen.

• Microsoft: present content in Teams meetings
• The broader Mac app-hiding workflow

Prepare the app you intend to show

Hiding other applications does not clean up the public app. Close unrelated browser tabs, switch away from live customer records and use sample data when possible. Check window titles, recent-file menus, autocomplete suggestions, the Dock and dialogs that could open over the material.

ScreenVeil can exclude a whole app or selected window from its own output. It cannot redact one tab, message, spreadsheet row or account inside an app you keep public. Put private browser work in a separate window or browser, then test that exact arrangement.

Turn on an appropriate macOS Focus too, and review its allowed people and apps. Focus can reduce notification banners; it does not hide a conversation, inbox or document already visible in the selected source.

• Keep private browser tabs out of a share
• Compare notification control with app filtering

How the Teams capture path works

Privacy Screen is an output window, not a system-wide recording block. ScreenVeil applies its exclusions to the capture it creates. Teams independently captures whichever source you select in its Share tray.

Set up Teams and macOS screen-recording permission

1. 1

   Prepare public sample content

   Open the apps you expect to show and use fictional or redacted material for the rehearsal.

2. 2

   Choose what stays private

   In ScreenVeil, mark whole apps or selected windows such as Slack, Mail, Messages or private notes. Do not mark an app private if you intend to present it.

3. 3

   Start and inspect Privacy Screen

   Switch among the public apps and confirm the feed updates. Practice ⌘⇧B, which covers Privacy Screen if something unexpected appears; it does not cover an unrelated Teams source.

4. 4

   Turn on Focus

   Choose an appropriate Focus and check its allowed people and apps. Visual filtering and notification control are separate layers.

5. 5

   Grant Teams permission if prompted

   Open System Settings → Privacy & Security → Screen & System Audio Recording, enable Microsoft Teams and relaunch Teams when required. Older macOS releases may label the pane Screen Recording.

6. 6

   Select the right Teams source

   In the Share tray, choose the window named Privacy Screen—not Screen, your private app or the ScreenVeil settings window.

7. 7

   Check the received picture

   Join from a second device or make a short test meeting and recording. Verify both that private sample content stays absent and that the public feed keeps updating.

• Apple: control screen and system-audio recording access
• Configure ScreenVeil for Teams

Test the audience view, not the picker thumbnail

A source name or thumbnail in the Teams picker is not proof that the live feed is correct. Watch from a second device while you scroll public content, bring each private sample app forward, switch between the public apps and use Cover feed. Stop if the output freezes or private content appears.

Repeat the rehearsal after changing displays or docks, installing a macOS or Teams update, or changing the apps in the workflow. A successful test supports that setup at that time; it is not a permanent compatibility guarantee.

Common boundaries to remember

What ScreenVeil does not promise

ScreenVeil can reduce accidental exposure in the Privacy Screen feed you choose to share. It does not block other software from recording the real display, suppress sound, identify sensitive text, redact part of a public app or verify the source selected in Teams.

For one prepared document, use Teams' built-in window sharing. Add ScreenVeil when the presentation genuinely needs several public apps while private apps remain usable on the Mac. Neither setup replaces access controls, consent, data-handling policy or an organization's security and compliance process.
