Activity Monitor:
Activity Monitor is similar to more details version of Task Manager on Windows
- Open Activity Monitor
- Either go to Applications > Utilities > Activity Monitor
- Or press Command+Spacebar and type "activity monitor", then select it from the results list
![Activity monitor window open showing a list of all processes running along with the resources they are using](https://td.cscc.edu/TDPortal/Images/Viewer?fileName=31c6b485-eb56-4d82-981a-99bb597936af.png)
If you select a process you can inspect its details (View > Inspect Process or Command+I) or kill it (View > Quit Process or Option+Command+Q). Since this displays system processes, be careful not to kill a process unless you're certain that doing so won't cause system problems.
