Summary: When you’re sharing your screen for a business or school presentation, you don’t want any notifications popping up, like a sext, a calendar notification for your therapist appointment, or a Slack DM about the problem client you’re currently presenting to. You could hit “Do Not Disturb,” but what if you forget? While Windows 10 has a built-in option to turn notifications off during screen-shares, OS X doesn’t. The free app Muzzle fixes that.
