Description
The macOS built-in Safari.app bookmark synchronization via the 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 bookmark synchronization must be controlled by an organization approved service.
ℹ️ Check
Verify the macOS system is configured to disable iCloud Bookmarks with the following command: /usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowCloudBookmarks').js EOS If the result is not "false", this is a finding.
✔️ Fix
Configure the macOS system to disable iCloud Bookmarks by installing the "com.apple.applicationaccess" configuration profile.
