Homebrew Cask for SystemEQ for Mac

🇬🇧 English | 🇮🇹 Italiano | 🇺🇦 Українська

System-wide parametric equalizer for macOS 13+ — main repository.

Installation

brew tap denzam/systemeq
brew install --cask systemeq

The cask automatically removes the macOS quarantine attribute on install, so the app launches without any Gatekeeper warning (SystemEQ is ad-hoc signed, not notarized with an Apple Developer ID — see the main README for the rationale).

Update

brew upgrade --cask systemeq

Uninstall

brew uninstall --cask systemeq

The cask's zap stanza also cleans up Application Support, Preferences and Caches:

brew uninstall --cask --zap systemeq

Requirements

• macOS 13 (Ventura) or later
• Apple Silicon or Intel Mac
• BlackHole 2ch (free virtual audio driver, installed via the in-app Setup Assistant)

For maintainers — updating the cask after a new release

1. Wait for the GitHub release workflow to publish SystemEQ-v<version>.dmg.
2. Compute the SHA-256 of the published DMG:

   curl -sL https://github.com/denzam/SystemEQ-for-Mac/releases/download/v<version>/SystemEQ-v<version>.dmg | shasum -a 256

3. In Casks/systemeq.rb bump version and replace sha256.
4. Commit and push:

   git commit -am "Bump SystemEQ to v<version>"
   git push

5. Verify locally:

   brew update
   brew info --cask denzam/systemeq/systemeq
