Install and activate

Two steps between the download and a running memory layer.

  1. 01

    Open the .dmg and drag Esment to Applications

    First launch: right-click Esment in Applications and choose Open — the app isn't notarized yet, so Gatekeeper needs a one-time override.

    On first launch the menubar icon appears and Esment asks for a license to activate.

  2. 02

    Activate with your license_id

    Without a valid license_id the app stays in lockout mode and refuses to start gated features.

    Sign in to get your license_idNo license yet — see pricing

What activating unlocks

The desktop runs the license check against the license-server every six hours. Without a current license you can install the app, but the API never starts and gated features stay off.
