How to See CPU Usage in OSX?

To see the CPU usage in OSX, you can make use of the Activity Monitor. The Activity Monitor is a utility tool that provides detailed information about the performance of your Mac, including CPU usage.

Here are the steps to view CPU activity in Activity Monitor on Mac:

1. Open the Activity Monitor by going to Applications > Utilities > Activity Monitor. Alternatively, you can use Spotlight search (Cmd + Space) and search for “Activity Monitor”.

2. Once the Activity Monitor window opens, you will see a list of processes and their resource usage. By default, the “CPU” tab will be selected, displaying the current CPU usage for each process.

3. To view the current processor activity, you can choose “Window” from the menu bar and then select “CPU Usage”. This will display a small floating window that shows the real-time CPU usage as a percentage.

4. If you want to view the recent processor activity, choose “Window” from the menu bar and then select “CPU History”. This will display a larger graph that shows the CPU usage history over time. You can customize the time range by selecting the desired interval from the drop-down menu at the top.

Additionally, the CPU activity is also represented by color-coded bars in the main Activity Monitor window. The color of the bars represents the level of CPU usage, with green indicating low usage and red indicating high usage.

By monitoring the CPU usage, you can identify any processes or applications that are consuming excessive resources, causing slowdowns or performance issues on your Mac. This information can be helpful in troubleshooting and optimizing your system’s performance.

The Activity Monitor provides a comprehensive overview of CPU activity, allowing you to track resource usage and make informed decisions to optimize your Mac’s performance.
