  "account": "Apple has launched the public beta 1 for macOS 27.3, following developer beta 1. The update brings several enhancements, with a focus on expanding Siri AI capabilities to four new languages - Traditional Chinese, Norwegian, Turkish, and Vietnamese. Alongside language support, the system introduces Vertical Tabs, Adaptive Dark Mode for websites, and tab management using Siri AI. Native Markdown rendering in Quick Look is also added, allowing .md file previews with proper formatting. Siri AI's reach extends to Apple’s own apps, enabling users to perform complex actions in Messages, Music, Calendar, Photos, and Reminders, as well as manage files and folders. Developers are provided with new tools to create advanced Siri AI integrations using Markdown-based instructions. Apple has added a new screensaver called Pro Lighteensaver, featuring light moving along metallic-looking lines forming the word \"PRO.\" The update also includes checks for potentially harmful content shared through public iCloud links, with Apple removing flagged content or taking action against violating accounts. The release build for macOS 27.3 public beta 1 is 26C5035r, identical to the developer build. To participate in the free public beta program, visit beta.apple.com.",
