1. Mac Gets Hot on Zoom? You’re Not Alone 🔥
If your Mac gets hot on Zoom, especially during long meetings or webinars, you’re part of a growing group of users dealing with thermal stress from video conferencing. Fan noise, lag, and a hot keyboard are signs your Mac is being pushed hard by Zoom—and potentially background apps as well.
Let’s break down why this happens and how you can cool things down fast.
2. Why Zoom Is So Demanding on macOS
Zoom isn’t just a video call—it’s also real-time encoding, decoding, screen sharing, and background processing. Add a virtual background or gallery view, and your Mac’s CPU/GPU are both under pressure. This leads to excess heat generation and rapid battery drain.
3. Background Apps Make It Worse
If you’re running Spotify, Slack, Chrome, or Dropbox during your Zoom call, your system might be juggling too much. That’s why your Mac gets hot on Zoom—it’s multitasking beyond what it can handle thermally.
Reducing these apps before launching Zoom can make a big difference.
4. Try These Quick Fixes During Zoom Calls
- Close unused browser tabs and apps before joining the meeting
- Use “Speaker View” instead of “Gallery View”
- Disable your virtual background
- Lower screen brightness and unplug if fully charged
Perfect if you need to keep other tools ready (like Photoshop or Xcode), but don’t want them draining your battery during meetings.
6. Bonus Tip: Test Zoom in Safari (Not Chrome)
Zoom in Chrome tends to use more resources than in Safari, thanks to WebKit optimization. If you’re using the web version, prefer Safari for better efficiency on Mac.

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.
