Take a look at what's going on inside your Mac with TG Pro - no other app shows more temperature sensors or has as many options for notifications and fan speeds. TG Pro also supports all features (ex: fan control) on the latest models, including the 2018 MacBook Pro, 2018 Mac Mini and iMac Pro. All Mac models from 2011-2018 are supported.

Find out which components are getting hot (and potentially overheating), turn up the fan speeds to cool down your Mac, get local and email notifications for temperature alerts along with many other fantastic features. Plus, see if any sensors, fans or the battery are defective with the built-in hardware diagnostics.

See why thousands of people trust TG Pro as the go-to app for temperatures and fan control. For added peace of mind, it also includes support for the Internet Access Policy so every possible Internet connection is documented when viewing them in Little Snitch.

An in-depth App Tutorial is also available to help get you started. For remotely deploying, we've got that covered too, with the Remote Deploy guide.

Download the free 14 day trial of TG Pro now.

This is the Rolls Royce of fan control and temp monitoring apps.
MacUpdate Review from Ryans
ZDNet recommends TG Pro in 2016 and and again in 2017
If you want to keep an eye on the temperature of the battery in your laptop...for Mac my choice would be TG Pro.

Of the very few number of Mac apps which monitor temperature and manage fans, TG Pro is the one I prefer.

Jeffrey Mincey from mac360.com

TG Pro helped diagnose a problem I suspected I was having with my fans and it was helpful to have it confirmed.

Mac App Store Review from Ylanthe
See the current and maximum recorded temperatures (in Celsius or Fahrenheit) for every temperature sensor in your Mac.
View and control the speeds for every fan. With Auto Boost, have the fans go to a specific speed when a predefined temperature is hit.
Always available status icon menu includes all temperatures, fans and manual controls.
Show a notification if a sensor or the Mac gets too hot, or when the fans are turned up with Auto Boost.
Monitor remote servers by having an email sent instead of a local notification.
Remotely deploy TG Pro by having it silently install the fan helper, setup preferences and register itself. See how in the Remote Deploy guide.
Discover faulty fans, temperature sensors and batteries with the built-in diagnostics.
Log all temperatures, fan speeds, diagnostics and notifications to a CSV file.
Run in the background with configurable info displayed in the menu bar.
Fix iMac fan noise after HD replacement. See how using TG Pro.
Supports all models: 2018 MacBook Pros, iMac Pro, Mac Pro 2013, MacBook Pros (including 2007-2018 models), iMacs, Mac Minis, MacBook Airs and older Mac Pros.
