I tried at least 5 similar Apps from the App Store and I was really upset about the poor output quality they produced. So when I came across MacMD I was hesitant at first, but I am so glad I went for it.5/5
I spend most of my day working with AI agents, and MacMD Viewer lets me quickly scan the many operational files we use, at a glance.5/5
Simple, fast, and exactly what you want when you double click on a .md file.5/5
I use MacMD Viewer to look at all the MD files Claude Code generates.4/5
MacMD Viewer is a native macOS application for reading Markdown files. It opens any .md file as a formatted document — headings, tables, syntax-highlighted code blocks and Mermaid diagrams — without editing it: the app is read-only by design, so the source file is never modified. It ships with a Finder Quick Look extension that renders Markdown when you press Space on a file, and twelve document themes that apply to both the app window and the Finder preview. The download is a 5.4 MB DMG that installs to about 16 MB on disk, runs natively on Apple Silicon and Intel, and requires macOS 14 Sonoma or later. It costs $19.99 as a one-time purchase — no subscription, no trial, no free tier — and is distributed as a direct download, through Homebrew and on Setapp.
MacMD Viewer is built for the read side of AI workflows. Coding agents and chat assistants — Claude, ChatGPT, Cursor, Copilot — write Markdown by default, so specs, plans and summaries land in project folders as .md files that macOS otherwise opens as raw text in TextEdit. MacMD Viewer renders those files as documents: point its Library at a folder and each file re-renders automatically when an agent or an editor saves it, thanks to live file watching. Roughly half of the people who buy it are not developers; they arrive holding a Markdown file that some other tool produced. Because it is a viewer rather than an editor, there is no cursor in the document and nothing to save — you read the output, and the tool that wrote it stays the only thing that writes it.
AI tools output Markdown by default. When you save or export the output, you get a .md file. MacMD Viewer lets you open it instantly, rendered with headings, code blocks, tables, and diagrams. No copy-pasting into another tool.
VS Code splits your workspace in half, takes 1-2 seconds to load, and doesn't render Mermaid diagrams. MacMD Viewer is a dedicated reader. Double-click a file and it opens rendered, like a PDF.
macOS opens .md files in TextEdit as raw text. MacMD Viewer registers as the default handler. Double-click any .md file and see it rendered with headings, code blocks, tables, and diagrams.
An editor lets you write Markdown. A viewer renders it for reading. Think Preview.app for PDFs, but for Markdown. You keep your favorite editor. MacMD Viewer handles the read side.
Yes. Flowcharts, sequence diagrams, state diagrams, Gantt charts, all rendered inline. Standard Mermaid syntax, no plugins needed.
You're covered either way: every purchase includes a full refund within 14 days, no questions asked. So there's no trial — you try it as an owner. At $19.99, it's less than one month of ChatGPT Plus.
MacDown hasn't been actively maintained. Marked 3 has moved to a subscription model at $69.99 permanent or $2.99/month. MacMD Viewer is a modern SwiftUI app with Mermaid, syntax highlighting, QuickLook, and live reload, for $19.99 one-time.
MacMD Viewer renders with print-quality formatting. Use macOS Print > Save as PDF to create a PDF from any rendered Markdown file. Output preserves code highlighting, diagrams, and formatting.

Claude Code barely touches your CPU — it is a memory problem. How much RAM you need, which chip matters, Air or Pro, and whether an M1 still holds up in 2026.

llms.txt is a markdown file at your site root. What the spec actually requires, who publishes one, why Google ignores it, and how to check yours is valid.
Plan mode blocks edits until you approve. How I read Claude Code plans on Mac before I do: Ctrl+G out of the terminal, QuickLook in Finder, live reload.
Convert Markdown to PDF five ways — browser tool, Pandoc, VS Code, online services, macOS — and stop relative-path images vanishing from the exported file.
