Tip for screensharing on Macs:

If you've never done so, you will need to give your browser (preferably Google Chrome) permissions to access Screen Recording.

We recommend doing this in advance of your event.

To do that:

> Open System preferences

> Click Security & Privacy

> Click Privacy

> Click Screen Recording on the left side

> Click the lock to make changes

> Check the box next to the browser (Google Chrome preferably)

After giving it permission to screen share you will need to close the browser (Google Chrome) and open it again.
