IT Home reported on October 27 that Apple today pushed the macOS 27.2 update (build number: 26B123) to Mac users, 28 days after the previous stable release.
Please note that, due to caching issues with Apple's regional server configurations, the update may be detected slightly later in some places, generally within half an hour.
IT Home consulted publicly available information and lists the main changes in this update below:
Expanded Siri AI languages: Support has been added for French, Japanese, Korean, Portuguese and Spanish. Together with the existing English support, six languages are now supported.
Siri contextual memory: Siri AI can retain useful context from earlier conversations and draw on a broader range of personal context to answer questions, such as referring to content it previously recommended or information across apps.
Smart suggestions in Messages: Based on the chat context, quick action suggestions are provided in apps such as Calendar and Reminders, for example to create an event or reminder directly.
Siri data scope and privacy controls: Siri AI can refer to photos in Messages, calendar participants, voicemail, Safari history and reading lists, among other information. An Excluded Apps setting also lets users choose which apps' data Siri, Search and system suggestions cannot access.
Interface and experience adjustments
Brightness and volume slider adjustments: When adjusted using the keyboard, the sliders now change in small, distinct steps.
Apple Music icon update: The app icon has changed from a red and white color scheme to a new black and white/blue design, as part of an Apple Music brand visual update.
Underlying preparations related to touch: The system has added code related to touch gesture recognition in apps including Safari, Photos, Notes and Quick Look. Apple has not formally introduced these features in the release notes, so for now they appear more like underlying preparations for a future touchscreen Mac or Sidecar use case than new features users can use directly.
