QLMarkdown
QLMarkdown is a QuickLook generator plugin for macOS that enables rich markdown rendering of .md files in the system's native QuickLook preview window. Instead of displaying raw markdown text, QLMarkdown interprets markdown syntax and shows formatted output with headings, emphasis, lists, code blocks and other markdown elements. It is distributed by Fiatdev and integrates with macOS QuickLook rather than operating as a standalone application.
AI Recommendation
1 suggestionQLMarkdown is a QuickLook plugin, not a standalone app, so it updates through the vendor's installer rather than through the App Store or a generic download page. To ensure you have the latest native Apple Silicon build, visit Fiatdev's website or GitHub repository and download the current QLMarkdown installer. After installation, run `qlmanage -r` in Terminal to reset the QuickLook cache and register the plugin. The plugin has been actively maintained with recent updates as of early 2025. If you encounter a security warning when launching the installer, this is a code-signing issue sometimes seen with small-vendor tools; you can temporarily allow the app through System Settings > Security & Privacy if you trust the source. Once installed, the QuickLook generator integrates directly with macOS and requires no further setup. Note that if Xcode is also installed, macOS may prefer Xcode's own markdown viewer for .md files — you may need to explicitly set QLMarkdown as the default handler or remove Xcode's QuickLook capability if you want QLMarkdown to take priority.
