We are facing an issue with Microsoft teams on mac devices. While screen sharing from mac device after some time the sharing window get terminated automatically. At that point the user is required to end the call and rejoin the meeting for screen sharing to work again.

Additionally , in some times teams become unresponsive (freeze) and the user needs to restart the device to continue using it.

    Hi @Abhijith P Ajith

    Regarding your issue, may I kindly ask a few questions to help understand it better? 

    • Does this issue occur only with this specific person or with multiple users, and do you see any additional error message?  
    • Do other users in your organization experience similar slowness or freezing, or does this seem to affect only you?  
    • Does this issue happen when you use Teams on the web or Teams desktop?  
    • Have you tried clearing the Microsoft Teams cache and reopening Teams to check if the freezing or screen‑sharing issue improves? For more details, please refer to: Clear the Teams client cache
    • Based on this Apple Community discussion, have you tried deleting the files under ~/Library/Metadata/CoreSpotlight/, then restarting the Mac to see if it makes any difference?

    On macOS, Teams screen sharing and app responsiveness depend heavily on OS permissions, display/docking configuration, and the Teams client version. For mac devices where sharing stops unexpectedly and the app freezes, use the following checks and mitigations:

    1. Verify macOS screen recording permissions for Teams
      • Go to Apple menu > System Settings > Privacy & Security.
      • Open Screen & System Audio Recording.
      • Ensure the Microsoft Teams toggle is turned On.
      • If permissions were changed, rejoin the meeting and start sharing again via Share in the meeting controls.
      • If using Teams on the web, also ensure the browser has screen recording permission.
    2. Avoid or reconfigure problematic docking setups on macOS 14+
      • There is a known issue on macOS 14 and higher where using DisplayLink or some docking stations affects sharing indicators and control panels.
      • If users are on macOS 14+ and connected through DisplayLink or similar docks, test:
        • Disconnecting from the dock and sharing directly from the built‑in display.
        • Updating dock/DisplayLink drivers and macOS to the latest version.
      • If the issue disappears when undocked, treat the dock/DisplayLink path as the root cause and adjust usage accordingly.
    3. Confirm Teams is allowed to start and maintain sharing
      • In a meeting, select Share.
      • If prompted, select Allow when Teams asks for screen recording.
      • If the prompt was missed, use Open System Settings from the pop‑up (when it appears again) to re‑enable permissions, then retry sharing.
    4. Try the native macOS content sharing path
      • In Teams, go to Settings and more > Settings > General > Screen sharing.
      • Enable Use macOS content sharing.
      • This switches to the native macOS sharing experience, which can be more stable on some Mac setups.
      • Note: Giving and taking control of shared content is not supported in this mode.
    5. Check for high‑motion sharing and performance impact
      • If users frequently share video or high‑motion content, Teams may increase frame rate, which uses more CPU/GPU and network.
      • High resource usage can contribute to freezes on constrained devices.
      • During a meeting, open More > Settings > Call health and review the Screen Sharing section (frame rate, resolution, bandwidth). If values are high and the device is under heavy load, reduce concurrent apps or switch to sharing a specific window instead of the full screen.
    6. Validate VDI/virtual desktop scenarios on Mac
      • If users connect from Mac endpoints into AVD/Windows 365 or Citrix and run Teams inside the virtual machine:
        • Ensure the environment meets the minimum versions for the new SlimCore‑based optimization.
        • Be aware of known Mac issues: slow mouse cursor during app sharing, problems when attaching/detaching external monitors during a call.
        • Outgoing screen sharing is disabled in end‑to‑end encrypted meetings on Mac VDI.
      • If screen sharing fails or freezes only in VDI sessions, test Teams directly on the Mac (outside VDI) to isolate whether the VDI optimization path is involved.
    7. Monitor and correlate issues centrally (admin)
      • In the Teams admin center, configure alerts for in‑progress meeting screen sharing issues:
        • Go to Notifications & alerts > Rules.
        • Use Audio quality for in‑progress meetings and configure Application sharing (VBSS) conditions.
      • Set thresholds for freeze, frame rate, sync, hardware failures, and loss recovery attempts.
      • Scope alerts to affected users/subnets and send notifications to a Teams channel or webhook.
      • Use these alerts plus Call Health data to identify patterns (specific macOS versions, docks, networks).

    If, after applying the above, screen sharing still terminates and Teams freezes, collect:

    • macOS version (including whether it is 14+ or 15.x/Sequoia),
    • Dock/DisplayLink usage,
    • Whether native macOS content sharing is enabled,
    • Call Health metrics during the incident, then escalate through Microsoft support with these details.
