Memory is an extremely light-weight utility to help you monitor your RAM usage. It runs in the status bar and displays currently available “Free” RAM. Clicking it shows a breakdown of how RAM is used by the system, separated into four sections: Free, Inactive, Active & Wired. It can display both absolute values in GB and percentages of total memory available, configurable in settings.


  • CoreGraphics is used for dynamically drawing graph images for displaying in the detail view
  • Uses sys and mach headers for getting access to system information and RAM usage
