This started happening when I upgraded my MacOs to Tahoe.

As soon as I start my screen sharing through teams desktop app, my entire macbooks starts lagging. I can notice the frames dropping and the performance dipping.

There are delays in mouse and keyboard inputs.

When the screen sharing is stopped, the mac reverts to normal.

This doesn't happen with other apps when the screen is sharing and neither happens when the screen is shared through teams web app.

    Hi @Naman Aggarwal

    Thank you for posting your question in the Microsoft Q&A forum. 

    Regarding your issue, although Microsoft has not yet published an official statement confirming the issue with Teams on macOS Tahoe, based on your description and recent user reports, it appears that the lag and freezing during screen sharing is related to the macOS 26 (Tahoe) update. 

    Many users have reported similar problems after upgrading, particularly when using Electron-based apps like Microsoft Teams. These issues include: 

    • Severe lag during screen sharing 
    • Mouse and keyboard input delays 
    • General system sluggishness 

    You can read more about these user experiences and potential workarounds in this Apple Community thread: Severe lag and freezing after macOS Tahoe update.

Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.  

    In the meantime, I suggest using the Teams web app instead of the desktop version for better screensharing experience and try the workaround given by the Apple community to see if it helps your issue. Also try submitting feedback to Apple via Product Feedback so they can prioritize a fix in future updates. 

    I apologize for the inconvenience this issue has caused you and hopefully it will be fixed in the future.
