How to enable screen recording permission for Chrome on macOS
Select the Apple menu (in the upper left corner of the screen).
Choose System preferences (Figure B).
Select Security & Privacy (Figure C).
Select Security & Privacy.
You may need to unlock before you change settings. Select the lock (Figure D, in the lower left corner), then a message and a prompt will display. Sign in, either with TouchID or with your system administrator account name and password.
Select the lock to allow changes, then authenticate (either with Touch ID or with an admin account and password).
Make sure the Privacy button is selected (from the tab across the top of the options), then scroll down and select Screen Recording (from the left menu).
In the box to the right, scroll until Chrome is displayed, then select the box to allow screen sharing (Figure E).
Scroll down to Screen Recording, select it, then check the box next to Google Chrome (to the right).
If Chrome is open, you may be notified that the setting will be applied only after Chrome quits (Figure F). Choose either Later or Quit & Reopen. I recommend Quit & Reopen.
If Google Chrome is active, you'll need to quit and then restart it before you begin your assessment.
Select the lock (in the lower left corner) to secure your settings.
After you've made the above changes, Emmersion may capture your screen on your Mac.
