macOS 27.3 beta lets Quick Look preview Markdown with formatting
Apple added formatted Markdown previews to Quick Look in the first beta of macOS 27.3.
The change means Mac users can preview .md files with headings, lists, links and other formatting instead of seeing the raw symbols.
Quick Look shows the preview without opening another app, making it easier to read these files.
Markdown is a plain-text format that people use for documentation and online writing.
Markdown is also used to give AI agents instructions, and Apple has added Markdown support to Notes and its new Siri app skills feature.
The feature is available in the macOS 27.3 beta, and the change is expected in that macOS release.
Apple’s macOS 27.3 beta 1 renders Markdown files with formatting in Quick Look.
The change means users can preview formatted content instead of seeing raw Markdown syntax.
The feature is available in the beta released on November 3, 2026.
Markdown can format headings, bold text, lists and links using plain-text characters.
