(Activity Monitor is a powerful utility for determining which processes on a Mac are using the most CPU time, RAM, energy, disk access, or network resources.) Clicking on the various tabs across the top will then show you details on CPU usage (by % of CPU used, CPU time, number of threads, and more), memory (RAM) usage, energy usage, disk usage, and network usage (sent and received bytes and packets). When launched, Activity Monitor displays a list of the processes currently running on your Mac (see screenshot below). The background processes are applications that are launched by the operating system at system startup in order to perform a variety of functions.
