Activity Monitor is a Mac utility that provides a real-time look at all running processes, both visible and hidden. It’s a great tool for troubleshooting performance issues, as well as for keeping an eye on what your Mac is up to behind the scenes. Here’s how to find and use Activity Monitor.
To launch Activity Monitor, open the Utilities folder in your Applications folder. You can also find it in the Launchpad or using Spotlight. Once Activity Monitor is open, you’ll see five tabs at the top of the window: CPU, Memory, Energy, Disk, and Network.
The CPU tab shows how much of your Mac’s processing power is being used by each process. The Memory tab shows how much memory each process is using. The Energy tab shows which processes are using the most energy. The Disk tab shows how much disk activity is taking place. And the Network tab shows how much data is being sent and received over your network.
To get more information about a process, select it in the list and then click the i button at the top of the window. This will open up a new window with more details about the process, including a graph of its recent activity. To quit a process, select it in the list and then click the x button at the top of the window.
Activity Monitor is a powerful tool, and it can be a little overwhelming at first. But with a little practice, you’ll be using it like a pro in no time.
