One thing that almost all Mac users can agree on is that they "just work", which is great, especially the tight integration with macOS and other Apple products. However when it comes down to seeing some of the more important statistics, they generally are either very hard to find or not available at all. That is until, TG Pro, which provides all internal temperatures including CPU, GPU, logic board, battery (for laptop models), trackpad/palm rest, Thunderbolt bolts and much more. Each Mac model has a unique set of sensors and TG Pro shows more than any other app.
In addition, it provides a listing of all fans, along with detailed specifications of the minimum, maximum and current RPM speeds. For users that could like a little bit more flexibility, TG Pro even offers the ability to control the fans by boosting them to help keep the Mac cool and running with maximum performance. This is done either through manual control or automated using Auto Boost rules.
To complement the temperatures and fan speeds, TG Pro also has built-in hardware diagnostics which let users know in advance if there's a problem with the Mac shutting down/sleeping unexpectedly, with the fans, the temperature sensors or the battery health. The battery health is important because it also shows the charge cycle count, which is how many times the battery has been depleted and recharged. Batteries are designed to last a specific number of charge cycles, with the ones in the MacBook, MacBook Air and MacBook Pros good for approximate 1000 cycles.
TG Pro is widely compatible with almost every single Mac model ever made as long as it's newer than 2008 and can run macOS 10.11 or higher. This includes the newest versions of macOS 11 Big Sur and macOS 12 Monterey. It also includes native support for both Apple silicon and Intel processors.

We recently released TG Pro 2.57 which has full support for the new Apple Silicon based M1 iMacs. It includes a full list of temperatures sensors including specific ones to the iMac such as the LCD panel and power supply.
In addition, it has full fan control which allows monitoring the fan speeds as well as boosting them to help cool it down when under heavy loads.
To download TG Pro to try it out for free, go to https://www.tunabellysoftware.com/tgpro/ and try it out today. If it's already installed, to update to the the latest version, click the TG Pro menubar icon, scroll down to the More submenu and choose "Check for Updates".
An interesting note, just like the other Macs with the M1 processor, even though there are 4 Efficiency Cores and 4 Performance Cores, it seems that the temperatures sensors do not match up one-to-one with the cores. From our research, we found so far two sensors for the Efficiency cores and seven sensors for the Performance cores. Our educated guess is that the performance cores need more monitoring, hence the larger number of sensors since they will work the hardest and generate the most heat.
Here is TG Pro running on the iMac (24-inch, M1, 2021):
