ThermalPulse is a macOS app for keeping an eye on what is going on inside your Mac and for taking control of the cooling fans. It is built with SwiftUI, Apple's framework for designing native Mac and iPhone interfaces, and the README describes it as lightweight with a glass-like translucent look that fits in with the rest of macOS. The current release listed is version 1.0.17. On the monitoring side, the app shows live CPU and GPU temperatures, how busy the processor, graphics chip, and memory are, how much disk space is used, and how much power the machine is drawing. These can be displayed inside a popover dashboard with charts, or as small icons in the menu bar at the top of the screen, with the user picking which numbers they want to see there. Updates happen in real time but are throttled to avoid using too many resources. Fan control is the second main feature. By default the Mac's own automatic fan logic stays in charge. If the user installs an extra component called a privileged helper tool, they can switch to manual profiles named System, Balanced, or Aggressive and adjust the fan speed directly. The README stresses that this is opt-in, requires explicit user permission, and uses Apple's standard ServiceManagement framework and XPC communication channels. When the app quits, the fans are returned to automatic mode. Internally the code follows the Model-View-ViewModel pattern, with separate layers for state, hardware monitoring, privileged operations, and the user interface. The README also mentions reactive updates through Combine publishers, persistence with UserDefaults, and thread safety with @MainActor. Requirements are strict: macOS 26 or later, and an Apple Silicon Mac with an M1 through M5 chip, with no support for older Intel-based Macs. Installation is either by downloading a .dmg and dragging the app to the Applications folder, or by cloning the source from GitHub and building it. The README lists localization and better error messages as outstanding to-do items.
