About
osu! (tachyon) is the tachyon release of osu!, a rhythm game. This Homebrew cask installs the macOS app osu!.app.
- The official project describes osu! as a rhythm game and identifies this client as an iteration of the osu! game client.
- The project supports user-created gameplay variations called rulesets, and provides templates for developers who want to build them.
- This cask installs the tachyon variant. It conflicts with the separate
osucask, so the two casks cannot be installed together. - The cask provides Apple Silicon and Intel download variants and places the app in
/Applications.
To install, run brew install --cask osu@tachyon. The official project lists macOS 12+ for its macOS releases. The project describes the client as under ongoing development; this package is a game app, not a development toolkit.
