Now, Hot can also display temperature and thermal throttling values for M1 Macs. In a nutshell, opening Hot made you crave an M1 Mac if that wasn’t already the case. It was very popular when we released it last year as it illustrated how quickly Intel Macbooks start experiencing degraded performance due to poor temperature management. It takes just one click to display CPU temperature and performance in detail. It detects CPU throttling due to thermal constraints. Hot is one of our tiny open source freebies. If your Mac’s performance drops due to high temperatures, which is known as thermal throttling, you can see this happening in real time through Hot. In the app, users will find an intuitive graph that shows the current CPU temperature and also whether the CPU is running at full speed. Once you download it, there’s no need to install it or even move it to the Applications folder. Unlike other more complex apps, Hot is extremely simple and easy to use. The Hot utility is part of the iMazing open source project, which means that it is completely free for anyone to use. IMazing, the company behind the popular iOS device management app of the same name, this week released an update to its utility app for macOS called “Hot.” The app is designed to let users monitor CPU temperature and throttling on Macs, and it’s now compatible with the Apple M1 chip.
