About
MacMD Viewer is a dedicated Markdown reader for the Mac. It renders .md files with formatted headings, code blocks, tables and Mermaid diagrams, the way Preview renders PDFs, so you can read what you or an AI agent wrote without opening a full editor. Press Space in Finder and it previews the file through QuickLook, and it live-reloads in about 50 milliseconds as the file changes.
Syntax highlighting, zoomable diagrams and tables, and a set of document themes (GitHub, Dracula, Nord and more) round it out. It is a one-time purchase from $19.99 for one Mac, with a Family Pack and team pricing, no subscription and no account, and a 14-day money-back guarantee.
