Maintain has served up Cocktail 10.2.1 (Sierra Edition), a new edition of Cocktail for users running macOS Sierra.
It’s a general purpose utility for macOS that lets users clean, repair and optimize their Macs. The new version adds support for unified logging, macOS Sierra 10.12.3 compatibility, and more.
Cocktail costs $19 for a single user license and available for purchase from the Maintain website (http://www.maintain.se/cocktail). When unregistered, Cocktail runs in demo mode and will expire after the tenth launch.
