MacDown 3000 review
A capable free editor for Mac users who need GFM, math, and HTML/PDF exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MacDown 3000 is a free, open-source Markdown editor for macOS, designed for people who write, preview, and export Markdown locally. It supports macOS 11.0 and later on Apple Silicon and Intel Macs, making it a focused option for Mac users working with notes, documentation, static-site content, or other Markdown files. Its core workflow combines a writing area with live preview, syntax highlighting for fenced code blocks, automatic bracket and quote pairing, and customizable Markdown rendering.
The editor covers several Markdown needs without adding a paid tier. CommonMark and GitHub Flavored Markdown support suit users who need familiar Markdown behavior, while TeX-like math notation, task lists, and Jekyll front-matter rendering extend it toward technical writing and static-site publishing. HTML and PDF export provide two practical output paths: HTML for web-oriented workflows and PDF for document sharing or archiving. The open-source model also makes MacDown 3000 a natural fit for users who prefer a free local application.
Its main trade-off is scope. MacDown 3000 is limited to macOS and is centered on local files, with no documented integrations or collaboration workflow. That makes it a clear choice for an individual Mac user who wants a focused Markdown editor with GFM support, live preview, math, front matter, and export. Teams needing shared editing, cross-platform access, or a wider connected publishing ecosystem should choose a different type of tool. Users who want a straightforward local editor and do not need those broader capabilities should find the feature set well aligned with everyday Markdown work.
