About

Zeal provides searchable offline programming documentation through downloadable docsets. This catalog entry points to an x86_64 Linux AppImage, not a macOS installer. The official website offers Windows and Linux downloads and directs macOS users to Dash.

How to install Zeal on Mac

  1. In Terminal, run: brew install --cask zeal

Install without Homebrew

Download the same file Homebrew uses: github.com/zealdocs/zeal/releases/download/v0.9.1/Zeal-0.9.1-x86_64.AppImage

Uninstall Zeal and optional data cleanup

Uninstall command
brew uninstall --cask zeal

A regular uninstall removes the app and keeps its settings and caches.

Deep clean (optional)

Uninstall command
brew uninstall --zap --cask zeal

--zap also deletes the settings, caches and other files listed in the Homebrew definition. They can include data shared with other apps and cannot be restored, and it does not guarantee that nothing is left. Back up any data you need first. To keep settings and caches, leave out --zap.
