Maintain has served up Cocktail 11.5 (High Sierra Edition), a new edition of Cocktail for users running macOS High Sierra.
It’s a general purpose utility for macOS that lets users clean, repair and optimize their Macs. Version 11.6 adds the ability to enforce critical (XProtect and Gatekeeper) security updates. It also adds compatibility with macOS High Sierra 10.13.5 and contains many under-the-hood optimizations for faster and more reliable performance as well as other improvements.
Cocktail costs $19 for a single user license and available for purchase from the Maintain website. When unregistered, Cocktail runs in demo mode and will expire after the tenth launch.
