It continues the legacy started by Chen Luo's [Mou](http://25.io/mou/) and carried forward by Tzu-ping Chung's [MacDown](https://macdown.uranusjr.com).\n\nVisit the [project website](https://schuyler.github.io/macdown3000/) for more information, or download from the [releases](https://github.com/schuyler/macdown3000/releases) page.\n\n## About MacDown 3000\n\nIn 2026, there's still a need for a modern, lightweight Markdown editor for macOS with live preview capabilities. MacDown 3000 is essentially *MacDown Continued*. The focus is on keeping MacDown up to date with modern Markdown best practices and maintaining compatibility with current library dependencies.\n\nMacDown 3000 supports macOS 11.0 (Big Sur) and later on both Apple Silicon and Intel Macs.\n\nThis project honors the original intentions and contributions of both Mou and MacDown while ensuring that this valuable tool remains available and actively maintained for today's Mac users.\n\n## Download \u0026 Install\n\n**Version 3000.0.5** - Available Now\n\n### Homebrew\n\nThe easiest way to install MacDown 3000 is with [Homebrew](https://brew.sh):\n\n```bash\nbrew install --cask macdown-3000\n```\n\n### Manual Download\n\nDownload the latest release from the [GitHub Releases](https://github.com/schuyler/macdown3000/releases) page. Open the DMG file and drag MacDown 3000 to your Applications folder.\n\n### System Requirements\n\n- macOS 11.0 (Big Sur) or later\n- Universal binary supporting both:\n  - Apple Silicon (M-series processors)\n  - Intel x86_64 processors\n\n## Screenshot\n\n![screenshot](assets/screenshot.png)\n\n## Features\n\n### Live Preview \u0026 Markdown Rendering\n\nMacDown 3000 uses Hoedown to convert Markdown to HTML with live preview as you type. It supports:\n\n- **Fenced code blocks** with language identifiers\n- **GitHub Flavored Markdown** including tables, strikethrough (enabled by default), and autolinks\n- **Task lists** for GFM-style checkboxes\n- **Customizable rendering options** in Preferences\n\n### Syntax Highlighting\n\nCode blocks get syntax highlighting via Prism, supporting numerous programming and markup languages.\n\n### Additional Rendering Tools\n\n- **Math notation** using TeX-like syntax ($$...$$, \\[...\\], \\(...\\), and optional $...$ blocks)\n- **Jekyll front-matter** for static site generators\n- **Export to HTML or PDF** with customizable styling\n\n### Editor Features\n\n- **Auto-completion**: Automatic bracket and quote pairing, list continuation, and formatting shortcuts (customizable or disable)\n- **Universal binary**: Built natively for both Apple Silicon (M-series) and Intel Macs\n- **Modern Markdown**: Supports CommonMark and GitHub Flavored Markdown\n\n## Development\n\n### Requirements\n\nIf you wish to build MacDown 3000 yourself, you will need the following components/tools:\n\n* macOS SDK (11.0 or later)\n* Git\n* [Bundler](http://bundler.io)\n\n\u003e Note: Old versions of CocoaPods are not supported. Please use Bundler to execute CocoaPods, or make sure your CocoaPods is later than shown in `Gemfile.lock`.\n\n\u003e Note: The Command Line Tools (CLT) should be unnecessary. If you failed to compile without it, please install CLT with\n\u003e\n\u003e     xcode-select --install\n\u003e\n\u003e and report back.\n\nAn appropriate SDK should be bundled with recent versions of Xcode.\n\n### Environment Setup\n\nAfter cloning the repository, run the following commands inside the repository root (directory containing this `README.md` file):\n\n    git submodule update --init\n    bundle install\n    bundle exec pod install\n    make -C Dependency/peg-markdown-highlight\n\nand open `MacDown 3000.xcworkspace` in Xcode. The first command initialises the dependency submodule(s) used in MacDown 3000; the second one installs dependencies managed by CocoaPods.\n\nRefer to the official guides of Git and CocoaPods if you need more instructions. If you run into build issues later on, try running the following commands to update dependencies:\n\n    git submodule update\n    bundle exec pod install\n\n## License\n\nMacDown 3000 is released under the terms of MIT License.

If you find problems when using those particular features, you can also consider reporting them directly to upstream projects as well as to MacDown 3000's issue tracker.\n\n## Support MacDown 3000\n\nDonations help cover the cost of the Apple developer license ($99/year).
