A slow or lagging Mac often means that your processor is not working harder than usual. High CPU usage can be a result of different reasons, such as demanding applications, background processes, or even software bugs. Fortunately, macOS includes built-in tools that allow monitoring processor activity and identifying which applications are using the most resources. Here, in this guide, we will tell you how to view CPU usage on mac and what to do if the usage is unusually high.
Why should you monitor CPU usage?
The CPU (Central Processing Unit) is basically the brain that carries out the instructions that keep your Mac going. Every app you open, plus background tasks, taps into some part of the CPU’s processing power, kind of all the time. If that usage stays high day after day, your Mac can start feeling sluggish; it may run hot, the fans get louder, and your battery life can take a real hit.
So, checking CPU usage regularly is a good idea. It can help you spot resource-heavy programs and handle performance troubles early, before they turn into something worse.
Check CPU Usage with Activity Monitor
The simplest method to watch CPU activity is to use Activity Monitor, which comes included with every Mac, with no extra download. To see the CPU usage with Activity Monitor, you need to adhere to the following steps:
Access the Finder to start the process.
Go to Applications, after which you need to look for ‘Utilities’.
Run Activity Monitor and locate the CPU tab.
On the CPU tab, you can see all running processes and the percentage of processor resources each one is using. If you sort by CPU percentage, the apps taking the most CPU usually show up near the top, which makes it easier to spot what’s bogging your Mac down.
Also, at the bottom of the window, there’s a quick overview of system-wide CPU usage. This includes how much power is being used by user applications, system processes, and even those idle tasks. These steps allow you to see Mac CPU monitoring.
Identify Resource-Heavy Applications
If you see one application consistently chewing through a big chunk of CPU, it might be behind the problem. This can happen when an app freezes, or it’s doing heavy work like video editing, or there’s some odd software bug causing it to loop.
Before you force quit anything, give the app a short window to finish what it’s doing, especially if it’s mid-task. If CPU usage stays unusually high with no obvious explanation, restarting the application often clears it up.
Monitor CPU Usage using Terminal
Another method that you can use to see CPU usage on your Mac is through the Terminal. The top command shows real-time information regarding all running processes, including memory and CPU usage. This method is quite useful for people who prefer command-line tools or look for detailed system information when troubleshooting.
