Description
The macOS built-in Photos.app connection to Apple's iCloud service must be disabled. Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, automated photo synchronization must be controlled by an organization-approved service.
ℹ️ Check
Verify the macOS system is configured to disable the iCloud Photo Library with the following command: /usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowCloudPhotoLibrary').js EOS If the result is not "false", this is a finding.
✔️ Fix
Configure the macOS system to disable the iCloud Photo Library by installing the "com.apple.applicationaccess" configuration profile.
