Screen sharing, a popular Zoom function, can have some issues with permissions on Mac machines, especially Macs managed by the University. This article covers specifically the issue of not being able to screen-share because an exclamation mark pops up in the window where a user should be able to select a web browser tag to share.
Solution
IMPORTANT: If you are running an outdated Mac OS like Catalina, be sure to upgrade your Mac OS if the solution below does not work.
- While trying to screen share, select the window with the exclamation mark error and click "Share" in the bottom right corner.
- A message should appear redirecting to Settings in Security & Privacy.
- If the user is not in a Zoom meeting, going to Security & Privacy in Settings by hand will work as well.
- Select the "Screen Recording" category if it's not already selected.
- Click the lock icon in the lower left and enter the password used to unlock the computer (the user's @maine.edu account password).
- Click the checkbox next to Zoom. This should prompt Zoom to quit or restart.
- Click the lock again to save the changes.
- You may need to repeat steps 3 through 6 for the Accessibility category as well.
- After restarting Zoom, the issue should be resolved.
