Apple macOS 27 Golden Gate is a major operating system release introducing new AI capabilities, productivity improvements, design refinements, security updates, and platform enhancements for Mac.

What's new

• Introduces Siri AI with a more conversational experience, improved personal context, and deeper integration with macOS.
• Expands Apple Intelligence capabilities across supported applications and workflows.
• Introduces Visual Intelligence on Mac for understanding and interacting with onscreen content.
• Adds enhanced AI-assisted photo editing and Image Playground capabilities.
• Improves Mail search with more relevant result ranking.
• Introduces additional accessibility capabilities, including richer VoiceOver descriptions and automatic video captioning.
• Provides design refinements, improved system responsiveness, faster AirDrop transfers, and enhanced Spotlight suggestions.
• Includes security fixes, bug fixes, and platform reliability improvements.

Compatibility impact

• macOS 27 is the final macOS release providing general Rosetta support for Intel-only applications on Apple silicon Macs.
• Organizations should identify remaining Intel-only business applications and plan migration to Apple silicon-native versions.
• Enterprise applications, endpoint security agents, MDM, VPN, SSO, certificates, printers, and other business-critical integrations should be validated before broad deployment.

Recommendation

Organizations should deploy macOS 27 initially to a controlled pilot group and validate business-critical applications, MDM, endpoint security agents, VPN, Wi-Fi, certificates, SSO, and peripheral compatibility before organization-wide deployment. Particular attention should be given to Intel-only applications that still depend on Rosetta.
