 ### iPhone notifications on macOS
 
 Apple's new [iPhone mirroring](https://www.apple.com/newsroom/2024/06/macos-sequoia-takes-productivity-and-intelligence-on-mac-to-new-heights/) feature allows users to receive iPhone notifications on their macOS devices. Keep in mind, some media types, such as Push Story images and GIFs, are not supported, since they can't be rendered as a macOS notification.

+### Apple Intelligence
+
+Starting in iOS 18.1, Apple launched the rollout of new [Apple Intelligence features](https://developer.apple.com/documentation/Updates/Apple-Intelligence). Most pertinent to Braze are notification preview summaries. This feature uses on-device processing to collapse and generate text summaries for groups of related push notifications from a single app. Summaries can be expanded to view the original contents of each individual notification.
+
+Since this is a user-enabled feature in the device settings, developers do not have control over the content or behavior of summaries generated by Apple Intelligence. Additionally, these summaries only affect the display of notification text when collapsed as a group and do not impact analytics reporting features, such as push click tracking.
