Control access to your photos on Mac
Some apps and websites can use your photos to provide you with services and features. You can decide which apps are allowed to use your photos.
Choose Apple menu > System Settings, then click Privacy & Security in the sidebar. (You may need to scroll down.)
Click Photos on the right.
Turn access to your photos on or off for each app in the list.
If you turn off access for an app, you’re asked to turn it on again the next time that app tries to use your information.
If you allow third-party apps or websites to use your photos, any information they collect is governed by their terms and privacy policies. It’s recommended that you learn about the privacy practices of those parties.
If you’re a systems administrator and want information about deploying security settings, see Apple Platform Deployment.
