What to do if you are in an online meeting on a Mac using Google Chrome and trying to share a full screen or an application window but nothing happens? 

Then you probably haven't allowed your Chrome to use screen recording. Follow these steps to make share screen functional.

  1. Open 'System preferences' on your Mac.
  2. Click on 'Security and privacy' and go to 'privacy'
  3. Now search for 'Screen recording' in the list and select it.
  4. Then make sure Google Chrome is checked. If it's not checked, click on it and a pop-up will appear.
  5. Click on close 'Quit now', this will close Google Chrome and restart it.
  6. Retry to share your full screen or application window
