Activity Monitor User Guide359

Activity Monitor is a powerful tool that helps you monitor the performance of your Mac. You can use it to see how much CPU, memory, energy, disk, and network resources your apps and processes are using. You can also use it to force quit apps that are not responding, and to view detailed information about your computer's hardware and software.

To open Activity Monitor, press Command+Space and type "Activity Monitor." You can also find it in the Applications folder, in the Utilities folder.

The Activity Monitor Window

The Activity Monitor window is divided into three main sections:
The toolbar, which contains buttons for performing common tasks, such as force quitting apps and refreshing the display.
The table view, which shows a list of all the processes running on your Mac. Each process is represented by a row in the table, and you can sort the rows by clicking on the column headers.
The inspector, which shows detailed information about the selected process. The inspector is divided into several tabs, each of which provides different information about the process.

Using Activity Monitor

To use Activity Monitor, simply select the process you want to monitor from the table view. The inspector will then display detailed information about the process, including its CPU usage, memory usage, energy usage, disk usage, and network usage. You can also use the inspector to view the process's environment variables, open files, and shared libraries.

If you want to force quit an app, select the app from the table view and click the "Force Quit" button in the toolbar. You will be prompted to confirm that you want to force quit the app. Click the "Force Quit" button again to confirm.

Tips for Using Activity Monitor
Use the search field in the toolbar to quickly find a specific process.
Sort the table view by CPU usage, memory usage, or other criteria to quickly identify the processes that are using the most resources.
Click the "Show All Processes" button in the toolbar to view a list of all the processes running on your Mac, including hidden processes.
Use the "Sample Process" button in the toolbar to sample the CPU usage of the selected process. This can be useful for identifying processes that are using a lot of CPU time but are not responding to keyboard or mouse input.
Use the "Record" button in the toolbar to record a log of the activity of the selected process. This can be useful for troubleshooting performance problems.

Conclusion

Activity Monitor is a powerful tool that can help you monitor the performance of your Mac. By understanding how to use Activity Monitor, you can quickly identify and resolve performance problems, and ensure that your Mac is running at its best.
