Available in the macOS App Store, PreviewMarkdown from Black Pyramid Software is a low-cost* native macOS Catalina utility that delivers QuickLook previews and full Finder icon thumbnails of documents styled using the popular Markdown markup format.
macOS has supported third-party QuickLook previews and icon thumbnails for some time. However, starting with Catalina, Apple deprecated the traditional means of enabling these features. PreviewMarkdown uses the new, future-proof Application Extension method, which will soon replace the traditional QuickLook Generators.
While Catalina continues to support QuickLook Generators, many of them no longer function because they are not signed by an official Developer ID. Because it is delivered through the App Store, this is not a problem for PreviewMarkdown.
PreviewMarkdown is open source software.
