Activity Monitor Tabs Explained
Now that Activity Monitor is open, let’s take a closer look at each tab.
CPU Tab

The CPU tab serves as your Mac’s performance indicator. The list in the tab is based on % CPU time to help you easily identify which apps or processes are taking up more than their fair share of resources.
Keep in mind that if your Mac is equipped with multiple cores, each core will be allocated 100% of its available processing power – thus pushing some programs over the total limit!
This tab will make it easy to identify the applications put in over time. When your Mac fan is running loudly or your laptop battery rapidly decreasing, quickly look at the CPU tab to see which apps are hoggin’ up resources. It’s possible that these software programs have gone rogue and need a reboot!
If you detect an application that is not operating correctly or appears to be stuck with the words “Not Responding” attached — simply click on its name and hit the X button in the toolbar. Activity Monitor will query if you wish to terminate this process; go ahead and press Quit for it to attempt quitting it normally.
In cases where this doesn’t yield any results, Press Force Quit instead -Activity Monitor can almost always shut down such a troublesome app quickly and efficiently.
Energy Tab

The Energy tab allows you to track the energy usage of your device. It displays a graph that shows which programs and services are using the most power, as well as other details such as battery level and temperature.
You can use Activity Monitor’s Energy tab to help determine which apps or processes are consuming too much power and causing your device to slow down. Armed with this information, you can then take steps toward optimizing the performance of your Mac.
For example, if Activity Monitor reveals that you detect that certain services are using more than their share of power, it might be wise to disable them or adjust their settings to reduce their impact on your device.
With Activity Monitor’s Energy tab at your disposal, you can easily and quickly assess the energy usage of your Mac – giving you all the info you need to keep your device running smoothly!
Memory Tab

The Memory tab of Activity Monitor provides insights into your Mac’s memory usage. It will display the total amount of RAM being used and how much is available.
This tab also lists all the programs that are currently running on your Mac, as well as their memory usage and related information such as process ID, status, user account, etc. Activity Monitor’s Memory tab can be used to quickly identify which apps or processes are using too much RAM and causing your Mac to slow down.
By keeping an eye on Activity Monitor’s Memory tab, you can ensure that your device has enough available memory for optimal performance – preventing any unnecessary slowdowns in the future!
Disk Tab

The Disk tab within Activity Monitor provides an overview of your Mac’s hard drive usage. It will display the total amount of disk space being used, as well as how much is available.
You can also view a graph that shows which apps and processes are using more than their fair share of resources. This can make it easy to identify any applications or services that are taking up too much disk space and slowing down your device.
Generally, users do not need to be concerned about the Disk tab. This indicates how much information is being written and read from your Mac’s drives. Writing or reading data also consumes power, so if you observe vast disk activity while noticing a decrease in battery life expectancy, take a look at which apps are triggering this situation.
If you notice a high level of activity within the cloud process, it could be due to downloading music, films, or photos for your Photos library. Additionally, this number may rise if you’ve worked on numerous files in iCloud Drive.
In short, the cloud is responsible for handling read and write operations from iCloud – so bear that in mind when monitoring its workload! If your storage drive is nearing its limit, you may want to explore ways to free up disk space on your Mac.
Network Tab

The Activity Monitor Network tab provides an overview of your Mac’s network activity. It will display the total amount of data being sent and received, as well as how much is available.
You can also view a graph that shows which apps and processes are using more than their fair share of resources. This can make it easy to identify any applications or services that are taking up too much bandwidth and slowing down your device.
Mac’s network activity contains hundreds of background processes that the normal user would not understand. Fortunately, even if you are unfamiliar with a process, it is likely benign and serves its intended purpose to the machine. It pays off to be aware of any strange behaviors or processes as these can usually be identified from here.
By keeping an eye on Activity Monitor’s Network tab, you can ensure that you have enough available bandwidth for optimal performance – preventing any unnecessary slowdowns in the future!
Cache Tab

The Activity Monitor Cache tab provides an overview of your Mac’s system cache. It will display the total amount of cached data, as well as how much is available.
Please note that if your Mac is running the content caching service, you will notice a sixth tab labeled Cache. This feature can aid in conserving bandwidth by storing copies of downloaded Apple server data, and this tab displays exactly how much content has been served, cached, and so forth.
By using the tab, you can gain insight into applications and services that are excessively consuming your device’s RAM cache. This graph will enable you to quickly detect any programs or processes that might be weakening your performance if left unchecked.
With this visual representation of resource usage, it becomes easier to identify potential issues before they become a problem!
Final Note
Activity Monitor is a powerful tool for Mac users and can be used to diagnose many different types of performance issues. By keeping an eye on Activity Monitor’s Memory, Disk, Network, and Cache tabs, you can ensure that your device has enough available resources for optimal performance – preventing any unnecessary slowdowns in the future!
