Activity Monitor categories

The Activity Monitor is comprised of many categories that include CPU, memory, energy, disk, and network. You can see active or background processes necessary to run your applications and system within each category.

CPU: See which processes are affecting your Mac processor.

Memory: View how your Mac’s memory is being used.

Energy: Review which applications are using energy and how much.

Disk: See how much data each process reads and writes to your disk.

Network: View how much data your Mac is sending and receiving over your network.

Activity Monitor data

As you select each of the above categories in the Activity Monitor, you will see a table of data, which can be sorted by column. The column headers you see can be customized. Just right-click on a column header and then check or uncheck those you want to see. If you want to rearrange the columns, just select and drag them where you want them. And you can customize the columns per category as well.

You also have handy graphs and additional data summarized at the bottom. For instance, on the CPU tab, you can see how many total processes are running and on the Energy tab. You can also get details on your battery.

If you see a process and want more information on it. Then select it from the list and click the Inspect selected process button in the toolbar or simply double-click the process. You can then view the parent process, percent of CPU that it uses, memory, statistics, and open files and ports as well.

However, if you want to stop a running process, select it from the list and click the Stop button in the toolbar. You can then choose to Quit or Force Quit the process. You can also Quit a process in the information window already described above.
