Cocktail

Cocktail is a macOS‑only utility that provides a range of system‑maintenance tools for cleaning, repairing, and optimizing a computer. It groups its functions into five categories, covering tasks such as verifying the boot volume, checking disk S.M.A.R.T. status, rebuilding launch‑services and mail databases, managing Spotlight indexes, and adjusting Time Machine settings. The application also offers memory‑purge and virtual‑memory controls, network‑card configuration, and options to disable features like App Nap or automatic termination of applications.

Users can run individual tools or activate an automatic Pilot mode that performs a predefined sequence of maintenance actions with a single click. The interface is designed to be straightforward, allowing both private individuals and organizations to access the various tweaks and diagnostics without needing deep technical knowledge.

Cocktail is positioned as a general‑purpose toolkit for macOS users who want to keep their systems clean, resolve permission or database issues, and apply performance‑related tweaks, and it is reported to be installed on hundreds of thousands of Macs worldwide, including personal devices, corporate environments, and educational institutions.
