TG Pro
TG Pro is a macOS utility that monitors internal temperatures, fan speeds, and battery health, and lets users manage Mac cooling.
What is TG Pro?
TG Pro is a Mac hardware monitoring and fan control utility for users who want more visibility into their system’s temperatures and cooling behavior. It helps you watch internal sensor readings such as CPU, GPU, logic board, drive, and battery information from a desktop window or menu bar view. The app also supports manual fan control, automatic rules that react to temperature changes, alerts, and temperature logging for troubleshooting or long-running workloads. Hardware diagnostics can help identify faulty sensors or fan-related issues, which is useful for older Macs, power users, and support workflows. TG Pro runs on macOS and is designed for people who want to keep a closer eye on thermals during demanding tasks such as video work, development, gaming, or sustained charging and battery use. It is published by Tunabelly Software Inc.

Safety overview
Status: Mostly safe
TG Pro is legitimate Mac utility software, but its fan-control features can affect how your Mac cools itself, so it should be used thoughtfully. Access to hardware monitoring and its helper components is normal for this type of app. Changing fan behavior too aggressively can increase noise or reduce cooling effectiveness if you choose unsuitable settings, so automatic rules or the default system behavior are the safer options for most people. If you only want temperature readouts, avoid unnecessary custom fan tuning.
Recommendation: Keep TG Pro if you actively monitor temperatures, diagnose heat issues, or use custom fan controls on your Mac. If you no longer use those features, you can remove it without affecting normal macOS use, though you will lose its monitoring history, alerts, and fan-management tools.
