Imark 0.6.6 for macOS 14 or later, 6.7 MB. If nothing happens, download it directly.

Or with Homebrew:

brew install --cask migsilva89/imark/imark

  1. 1

    Move Imark to Applications

    Open the disk image and drag Imark across. macOS only trusts the Quick Look extension from apps in the Applications folder.

  2. 2

    Open it once

    Double-click Imark. It is signed and notarised by Apple, and opening it registers the Finder preview.

  3. 3

    Press Space on any .md file

    Select a Markdown file in Finder and press the space bar. To make Imark the default, press Command-I on a .md file, choose Imark, then Change All.
