Apple macOS Sonoma (14) Update Version macOS Sonoma 14.2

macOS Sonoma 14.2 release notes for December 11, 2023 cover new iMessage Contact Key Verification, StoreKit and SwiftUI enhancements, and several resolved issues. The update also includes a ServiceManagement security hardening change and a known beta limitation for Learn More links.

• iMessage Contact Key Verification adds stronger message identity verification using Key Transparency and contact verification codes.
• ServiceManagement now requires sandboxed target executables for sandboxed apps to prevent sandbox escapes.

• Messages: fixed an unlocalized member count string in full-screen Map View for Group Messages.
• StoreKit: fixed refund sheet dismissal in StoreKit Testing, and corrected StoreKit 2 device verification that could cause transaction verification failures.
• Swift Charts: fixed scrollable charts not respecting the initial non-zero chartScrollPosition binding value.
• SwiftUI: fixed a possible access conflict crash with toolbar items and changed ImageRenderer update behavior to avoid unintended dependency cycles.
• WidgetKit: fixed Text(_:style:) in widgets not animating content by default.
• Contact Key Verification: fixed several beta issues, including missing verification codes, missing checkmarks, transcript errors, and eligibility problems.

• iMessage Contact Key Verification lets users verify they are messaging only with intended contacts and compare verification codes in person, on FaceTime, or through another secure call.
• StoreKit adds new Transaction pricing properties: price, currency, currencyCode, and offer details including offer, offerID, offerType, and offerPaymentMode.
• SwiftUI adds _logChanges() for logging why a view updates, with output sent to the system console.
• iMessage Contact Key Verification supports saving a public key for a contact to enable verification with that person.

• The Learn More links do not link to Knowledge Base articles during Beta.

• All devices signed into the same iCloud account must be on at least iOS 17.2 Beta, macOS 14.2 Beta, or watchOS 10.2 Beta to enable iMessage Contact Key Verification.
• If older OS versions must remain in use, sign out of iMessage on those devices before enabling Contact Key Verification.
• The macOS 14.2 SDK is bundled with Xcode 15.1.
• For sandboxed apps using SMAppService, the target executable must also be sandboxed; a small sandboxed trampoline tool can be used to run scripts or unsandboxed/system tools.
