Working with multiple programs at the same time could slow down the performance of your system. One solution for this type of problem comes from App Tamer, a utility that provides you with an efficient way to reduce CPU usage for the applications that you're currently not using, but are operating in the background.
The program lives on your Menu Bar from where you can access real-time information regarding the current CPU usage for every running app on your Mac. From the same menu you can access the app's Preferences panel and Quick Start Guide.
Besides allowing you to monitor which apps use the most of your CPU resources, this program also enables you to easily quit or relaunch running utilities. App Tamer is also packed with a built-in search tool that helps you immediately find the program or process that's slowing down the performance of your system.
The only disadvantage I was able to find while testing this program was the fact taht I had to download and install an additional tool in order to use App Tamer on my Mac. Still, the app completed the task for me and it didn't take long to install the aforementioned utility.
In conclusion, App Tamer proves to be a reliable solution for taking control of the programs that consume large amounts of CPU resources while operating on your Mac. It's efficient, easy-to-use, and affordable.
