Temperature monitoring, fan control & diagnostics.

Stacks Image 3908

Extend the life of your Mac with TG Pro by monitoring all internal temperatures to know which components are hot or potentially overheating.

Quickly view CPU, GPU, logic board or hard drive temperatures, check battery health and the other hardware diagnostics. If it's getting hot, manually boost the fan speeds, or allow TG Pro to do it automatically to help keep the Mac cool and running fast. Get local or email notifications for temperature events along with full logging for further analysis.

It's designed with security in mind. TG Pro is Notarized and uses the Hardened Runtime. It also has a separate secure service for fan control, only HTTPS/SSL connections and support for the Internet Access Policy for Little Snitch.

TG Pro supports all Macs from 2008 and newer, with specific support for multiple models including 2018 and 2019 MacBook Pro, MacBook Air, Mac mini and iMac.

TG Pro requires macOS 10.10 or newer. Compatible with Mojave and Catalina.
One license is valid for up to 3 Macs for personal use. Business use requires one license per Mac.
No subscription required.
All updates to 2.x are free.

Every Mac

TG Pro works on all Mac models, regardless if it's an older one from 2008 or a brand new one from 2019. It even works on Macs with the T2 security chip.

It knows what's available for each model so it can adapt to show more temperature sensors than any other app.

As a bonus, it even works with Hackintosh models by simply enabling a preference.

Mac Health

It's all available in TG Pro. In one window, view all internal temperatures, fans and hardware diagnostics.

It's the best way to easily check that all vital components inside your Mac are working properly. TG Pro will even tell you if the Mac shutdown because it overheated, or if the battery needs servicing.

Always On

TG Pro runs unobtrusively in the background using minimal resources.

Use the menubar icon to quickly view all internal temperatures and access fan controls.

Auto Fan Control

Use Auto Boost rules to decide how the fans should be boosted based on temperatures from any sensor or highest CPU.

These can even be used to completely override the system control of the fans for a custom fan curve. The perfect way to fix an iMac where the fans go full speed after a HD replacement.

Instant Cooling

Wish the fans kicked in sooner? Use Manual mode to instantly boost them to maximum speed to cool down your Mac right away.

TG Pro cools Average CPU from 87℃ to 81℃

Stay Informed

Get informed about thermal and diagnostic events via the macOS Notification Center, emails or a CSV log file.

Mojave & Catalina

Dark or light mode, it doesn't mater - TG Pro looks great in both on either macOS Mojave 10.14 or Catalina 10.15.

In addition, on Catalina it is Notarized by Apple, and uses the Hardened Runtime to ensure it's the original from Tunabelly Software and hasn't been tampered with.
