Cocktail20.2.1

Cocktail cleans, repairs, and optimizes a Mac through one general-purpose utility, giving users maintenance tools and system adjustments in a single interface. Its controls are organized into five categories, while automatic Pilot mode can carry out essential maintenance after one button press.

It can check disk S.M.A.R.T. status, enable journaling, set disk-sleep timing, alter other disk settings, and rebuild Launch Services, Help, Accessibility, or Mail’s Envelope Index databases. Memory tools purge inactive memory, optimize virtual-memory use, or disable virtual-memory swapping. Time Machine controls modify its settings, thin or delete snapshots, and display its log; other options force-empty the Trash, disable automatic application termination, turn off App Nap or Notification Center, and enforce critical security updates.

Cleanup covers system, user, Internet, and application caches, corrupted preference files, unnecessary localization resources, invisible DS_Store files, locked items, and inaccessible items, with scheduling for cache and log clearing. Users can view, print, save, and delete log files, adjust network-card speed, duplex, and MTU, optimize settings for common connection types, modify IP parameters, configure File Sharing, and change hidden settings in Calendar, Launchpad, Music, Photos, Safari, and Terminal.

Cocktail suits private Mac users as well as companies, educational institutions, and newspapers that need recurring maintenance or targeted troubleshooting. It is freeware for macOS, with the current release listed as version 20.2.1 for Apple Silicon (arm64); the developer also presents Golden Gate for macOS 27 as 20.2, Tahoe for macOS 26 as 19.10.1, and Sequoia for macOS 15 as 18.9.
