How to share screen on teams mac

Worried that Microsoft Teams share screen is not working on Mac? Don’t be, you’re not the only one facing this issue.

When talking about Teams, most users try to do their daily routine by simply opening it and joining a meeting. Afterward, they select the Share screen button and choose to present their entire desktop, a PowerPoint file, a window, or a whiteboard.

That’s how it should usually work, yet Microsoft Teams gets its fair share of issues these days.

Other users only get a pop-up and discover that the share screen is not working on Mac. In some cases, Microsoft’s latest updates can cause this. After all, several other apps are behaving weirdly on Apple’s macOS Catalina.

They might take some time, but you should be in the clear afterward.
