Allow accessibility apps to access your Mac
When a third-party app tries to access and control your Mac through accessibility features, you receive an alert, and you must specifically grant the app access to your Mac in Privacy & Security settings.
If you’re familiar with an app, you can authorize it by clicking Open System Settings in the alert, then turning on permission for the app in Privacy & Security settings. If you’re unfamiliar with an app or you don’t want to give it access to your Mac at that time, click Deny in the alert.
To review app permissions—for example, if you later decide to give a denied app access to your Mac—choose Apple menu > System Settings, click Privacy & Security in the sidebar, then click Accessibility on the right. (You may need to scroll down.) Turn permission on or off for any app in the list. If you don’t see the app you want to grant permissions for, click the Add button at the bottom of the list of apps, search for the app, select it, then click Open.
