Dear @Jerome Angelo,
Welcome to the Q&A Community. Thank you for sharing your concerns.
I appreciate you reporting the issue related to bandwidth drops during screen sharing in Microsoft Teams on your Mac. I understand this is significantly impacting your daily work, and I’d like to share some context and potential workarounds that may help improve performance.
When sharing your screen in Teams on macOS, especially with high-motion content, the app may throttle bandwidth and frame rate to manage system resources. This can result in a drop from 1 Gbps to as low as ~4 Mbps. This behavior is more common on Mac devices due to how Teams handles screen sharing and hardware acceleration.
For a more in-depth explanation, please see the article below: Monitor call and meeting quality in Microsoft Teams - Microsoft Support
Here are a few steps that may help mitigate the issue:
1/ Make sure both Microsoft Teams and your macOS are updated to the latest versions. In Teams, click your profile picture > Check for updates.
2/ Close any unnecessary applications, especially those that use GPU resources (e.g., design or video editing tools). This helps free up system resources for Teams to run more efficiently.
3/ Use Ethernet Instead of Wi-Fi
A wired connection can help maintain stable bandwidth.
4/ Turn Off Video and Background Effects
Disabling these features can reduce bandwidth usage during meetings.
5/ Verify that your Mac allows screen recording for Teams. Go to System Preferences > Security & Privacy > Privacy > Screen Recording, and ensure Microsoft Teams is checked.
6/ You might want to try clearing the Teams cache to improve performance. Please note that this will sign you out of all accounts, so be prepared to sign back in.

7/ Use Teams in a Web Browser (Microsoft Edge or Chrome)
Running Teams in a browser can reduce system load compared to the desktop app.
If the issue persists, consider fully uninstalling and reinstalling the Teams desktop app to reset any corrupted settings or cache.
I hope these workarounds can help mitigate some of the disruption and make your workflow a bit smoother.
