Using Activity Monitor to Diagnose Performance Issues

If you suspect your Mac is running slow or experiencing performance issues, Activity Monitor can help you identify the problem. Here are some tips for using Activity Monitor to diagnose performance issues.

Check for high CPU usage

If your Mac is running slow, it might be due to a process consuming a high percentage of your CPU resources. Look for processes with unusually high CPU usage in the CPU tab and consider quitting them if they’re not essential.

Monitor memory usage

Insufficient memory can cause your Mac to slow down. In the Memory tab, check the Memory Pressure graph at the bottom of the window. If the graph is consistently red, you may need to close some applications or consider upgrading your Mac’s RAM.
