Graf is a menu bar utility for macOS that displays live system statistics. It presents a real-time CPU sparkline directly in the menu bar, and a single click opens a popover showing CPU load, memory pressure, network upload and download rates, and disk usage. The app reads the same public system counters that Activity Monitor uses and requires no special permissions, such as Screen Recording or Accessibility access. It installs and runs without any configuration or prompts. The application is designed to be lightweight and efficient, using minimal system resources so it does not affect the performance it monitors. It does not generate alerts, badges, or notifications; information is available only when the user chooses to look at it. Graf is a native Mac app that runs quietly in the background, updating the sparkline every second without becoming intrusive. A typical use case is checking system status when the Mac’s fans become audible. Instead of opening Activity Monitor, a user can glance at the menu bar sparkline to see if CPU usage is elevated, then click to examine memory, network, and disk activity for a more complete picture. Graf is part of the Mac Utility Bundle, a one-time purchase of $19.99 that includes several other Mac-only utilities, such as a menu bar calendar (Calebar), a menu bar organizer (Barmony), and a keep-awake tool (Sleepover). Future utilities added to the bundle are automatically included for existing purchasers. The app requires macOS and a Bravely account to unlock the purchase.
