GoKawiilmacOS 27.3 beta adds Markdown rendering to Quick Look
Apple's macOS 27.3 beta 1, released alongside new Safari and Siri features, lets Quick Look render .md files with proper formatting instead of showing raw Markdown syntax. The update follows Apple's broader push to support Markdown across its platforms, including import/export in Notes and Markdown-based SKILL.md files used by its new Siri AI developer framework.
GoKawiil's interpretation of the reporting above, not reported fact.
The change suggests Apple sees Markdown as increasingly central, not just for writers and developers but for AI agents that rely on .md files to store instructions and context. By making these files easier to read natively, Apple could be positioning macOS as more friendly to both human documentation workflows and emerging AI tooling.
