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.
On your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click Privacy.
Select the checkbox next to an app to allow it to access information from Photos. Deselect the checkbox to turn off access for that app.
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.
For systems administrators who want information about deploying security settings, see the Deployment Reference for Mac.
