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.Click Photos.
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 prompted 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 information, you are subject to their terms and privacy policies and not the Apple Privacy Policy. You should review their terms and privacy policies to understand how they treat and use your information. See the Apple Privacy Policy.
