Permissions issues

In order to share your screen, you need to ensure that MacOS has given the screen recording permission to your browser (Chrome, Firefox, Safari or Edge). If the system level permission is not enabled, this can block screen sharing access to video calling applications such as Evidenced and Google Meet.
​
When attempting to screen share in Evidenced you may see this dialog:

If this happens, on your Mac you'll need to navigate to Security & Privacy > Screen Recording settings in your macOS System Preferences, and make sure your we browser (Chrome, Firefox, Safari or Edge) is enabled. To open your macOS Screen Recording settings click here. For more detailed instructions, see below.


Detailed instructions

  1. Go to the Apple icon in the top left corner of your screen.
    ​
    ​

  2. Select System Preferences.
    ​
    ​


    ​

  3. Select Security & Privacy.
    ​
    ​


    ​

  4. Click the lock icon at the bottom to make changes.
    ​
    ​


    ​

  5. Enter your password to unlock.
    ​
    ​

  6. Find the Screen Recording option under the Privacy tab.
    ​
    ​

  7. If you do not see your web browser (Chrome, Safari, Firefox or Edge) in the screen recording section, click the plus icon and select your browser from your applications folder, and then click Open.
    ​
    ​

  8. If the web browser is already checked, uncheck and then recheck the box.
    ​
    ​


    ​

  9. If the web browser is not already checked, check the box.
    ​

  10. Click the lock icon to prevent further changes.
    ​

  11. Quit and reopen your web browser. Make sure you fully quit the browser for the changes to take effect:

    1. Quit and reopen:

      • Mac: Hold ⌘ + q.

      • Windows: Hold Ctrl + q.

    2. Tip: You can reopen any tabs that were open before:

      • Mac: Press ⌘ + Shift+ t.

      • Windows: Press Ctrl + Shift + t.

You should now be able to ​return to your Evidenced interview and share your screen as normal.

Screen appears blurry when sharing

If you're sharing your screen or a window from Safari and another call participant says that your screen looks blurry, this is a known issue with some versions of Safari.

In this case, the best option to resolve the issue quickly is to switch to another one of our supported web browsers: Chrome, Firefox or Edge.
