TG Pro

TG Pro (Temperature Gauge Pro) is a powerful, professional system utility application for macOS that gives users comprehensive control over their Mac's thermal performance.

It's an essential tool for power users, developers, and anyone who pushes their Mac hardware to its limits (e.g., video editing, gaming, heavy computational tasks).

Key Features of TG Pro

TG Pro's strength lies in its ability to provide deep insight and control over the Mac's cooling system:

• Real-Time Temperature Monitoring:

  • Shows readings from every available sensor inside your Mac—often far more than what the default system provides. This includes CPU, GPU, SSD/HDD, battery, logic board, ambient air, and individual CPU cores (on Apple Silicon).

  • Tracks the maximum recorded temperature for each sensor.

• Full Fan Control (Intel & Apple Silicon):

  • Manual Control: Directly set fan speeds to a fixed RPM.

  • Auto Boost Rules: Create custom rules (fan curves) that automatically adjust fan speeds based on specific sensor temperatures (e.g., "If the CPU hits $85^{\circ} \text{C}$, spin the fan up to 5000 RPM"). This prevents thermal throttling and overheating.

  • Max Setting: Quickly engage maximum fan speed for immediate cooling needs.

  • Note: On fan-less Macs (like some MacBook Air models), you can still use the app to monitor temperatures and diagnose overheating issues.

• Diagnostics and Alerts:

  • Hardware Diagnostics: Provides information to check if any sensors or cooling fans are defective.

  • Notifications & Email Alerts: Receive pop-up notifications or email alerts when component temperatures exceed user-defined safe limits.

  • Logging: Record temperatures and fan speeds to a log file (CSV) for later analysis or troubleshooting.

• User Experience:

  • Menu Bar Integration: Quick access to key temperature data and fan presets directly from the macOS menu bar.

  • Modern UI: Features a clean, native macOS interface optimized for both Intel and Apple Silicon (M1, M2, M3, etc.) Macs.

TG Pro is a highly recommended utility for Mac users, especially those performing intensive tasks, as it provides the necessary visibility and control to manage thermal performance, reduce overheating, and extend the lifespan of their hardware.
