Cooler

Cooler is a macOS utility designed for developers and power users who need to monitor and manage system temperature and thermal performance. It provides real-time temperature readings from CPU, GPU, and other thermal sensors, and allows users to configure fan speed settings to help keep their Mac cool during intensive development tasks, video encoding, 3D rendering, or other high-load workloads. The app is typically used by developers working with resource-intensive IDEs, compilers, and build systems.</description> <parameter name="recommendation">We could not find public information about whether Cooler has a native Apple Silicon build. The developer's site appears to have limited or outdated information. If you rely on this app, contact the developer (Moshe Berman) directly to ask whether a native Apple Silicon version is planned or already available, especially given that Apple will remove Rosetta 2 support in macOS 28, scheduled for September 2028 — giving you less than 2.5 years before Intel-only apps will stop launching entirely. In the meantime, Cooler continues to run under Rosetta 2 on Apple Silicon Macs, so there is no immediate urgency. For system temperature monitoring as a contingency, many users find that built-in Activity Monitor (Applications → Utilities) and free tools like Macs Fan Control offer similar temperature-tracking capabilities on newer Macs, though neither is a perfect replacement for Cooler's feature set.
