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.
