1. Mac Gets Hot While Using Microsoft Teams? You’re Not Alone 🔥
If your Mac gets hot while using Microsoft Teams, especially during video calls or when screen sharing, you’re far from the only one. Teams is known to be resource-hungry on macOS, causing fan noise, battery drain, and performance lag—even when the app appears to be idle.
Let’s break down why Teams is so demanding—and how to fix it without quitting everything.
2. Why Teams Overheats Your Mac
Here’s what Microsoft Teams does in the background:
- Uses CPU and GPU for real-time video/audio encoding
- Stays active in the menu bar—even when closed
- Constantly syncs messages, updates, and presence status
- Often launches multiple helper processes
That’s why your Mac gets hot while using Microsoft Teams—it’s always doing something, even when you’re not in a meeting.
This keeps your Mac cool, responsive, and ready for your next meeting.
4. Tips for Using Teams Without Overheating Your Mac
- Close other video apps (Zoom, Meet) when using Teams
- Use Teams in Safari (less CPU usage than the desktop app)
- Turn off background blur and effects during calls
- Lower screen resolution if sharing large visuals

Where AppHalt may help
If Activity Monitor shows a regular app you recognise using resources while you do not need it, AppHalt gives you a reversible option: pause that selected app without quitting it, then resume it later. AppHalt does not repair macOS or guarantee a speed, temperature, battery, or stability result; the effect depends on what the app was doing.
Do not pause an app that is uploading, syncing, backing up, rendering, recording, playing media, or handling a call you need to continue.
