How do I install OciDeck on macOS with Homebrew?

Are you using Homebrew? Then execute these two commands. The first points Homebrew to our own forge, the second installs OciDeck:

brew tap librekat/ocideck https://pawprint.vigilis.online/LibreKAT/homebrew-ocideck.git
brew install --cask librekat/ocideck/ocideck

The address line is really part of it. If you leave that out, Homebrew will search GitHub and find nothing.

This is the canonical route: both the recipe and the app come from our own forge. If the forge is temporarily unavailable, the GitHub mirror is the backup copy. This is done in one command, because the short form of Homebrew by definition points to GitHub:

brew install --cask brennodewinter/ocideck/ocideck

However you install, Homebrew pulls the release directly from our own forge and checks the checksum automatically. The app is signed with an Apple Developer ID and notarized by Apple, so it then opens with a simple double-click.

To update to a later version, run:

brew upgrade --cask ocideck

The cask is only a pointer to that same signed, notarised release; Homebrew does not host the app itself and no extra intermediary is involved. Homebrew Cask exists only for macOS — on Windows and Linux you download OciDeck directly.

Prefer not to use Homebrew? Then download OciDeck directly from the OciDeck page. That page also explains, per platform, how to open and verify the download.
