Installation

  1. Download

    Get the latest DMG from the link above.

  2. Install

    Drag Equaliser to your Applications folder.

  3. Launch

    Right-click and select Open on first launch to bypass Gatekeeper.

    Trouble launching?

    macOS Gatekeeper may block Equaliser because it's not notarized by Apple.

    If the app won't open, go to System Settings → Privacy & Security and click Open Anyway next to the security warning.

    I currently don't want to pay Apple $99/year to let the app through Gatekeeper.
    I may reconsider if it is requested.
