macOS 27.3 adds native Markdown rendering to Quick Look, Siri skills use SKILL.md
timigod · x · 2026-11-04
Apple's macOS 27.3 beta 1 renders .md files with proper formatting directly in Quick Look instead of raw syntax.
Key points:
- Apple is expanding Markdown support across platforms; Notes already imports/exports .md files.
- The new Siri AI developer framework officially uses skills, with developers writing Markdown-based SKILL.md files to instruct Siri on complex in-app tasks (spotted by Federico Viticci).
- Markdown is rising with the AI agent era: agents increasingly store instructions and context in .md files.
