Extend the life of your Mac using TG Pro.

Whether it's a brand new 2023 MacBook Pro with M2 Max, a Mac Studio, a classic Intel iMac or anything in-between, it will help to keep it cool and running at peak performance. It supports all Intel and Apple Silicon processors including the M2 Ultra, M2 Max, M2 Pro, M2, M1 Ultra, M1 Max, M1 Pro and M1.

See what was previously hidden, by viewing CPU, GPU, logic board, battery and HD temperatures, check hardware diagnostics to find problems before they occur, as well as fan speeds. If the Mac starts to get too hot, it's easy to either manually boost the fan speeds to improve cooling, or let TG Pro do it automatically using rules.

In addition, get local or email notifications for temperature and diagnostic events, along with full logging to a CSV file for further analysis.

It's designed with security in mind. TG Pro is notarized by Apple and uses the Hardened Runtime. It also has a separate secure service for fan control, only HTTPS/SSL connections and built-in support for the Internet Access Policy (when using Little Snitch).

It is fully compatible with macOS 14 Sonoma, all the way back to macOS 10.13 High Sierra.

TG Pro natively supports both Intel and Apple Silicon Macs, from 2008 all the way up to the latest models. This includes MacBook Pro (13, 14, 15 and 16 inch), iMac (21.5, 24 and 27 inch), iMac Pro, Mac Pro, MacBook, MacBook Air (13 and 15-inch), Mac mini and Mac Studio.


Intel & Apple Silicon

TG Pro runs on macOS 10.13 or higher, regardless if it's a classic from 2008 or a brand new one from 2023. This includes Intel models with or without the T2 security chip and Apple silicon (M1, M1 Pro, M1 Max, M1 Ultra, M2, M2 Pro, M2 Max & M2 Ultra).

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.
