This article describes some of the commonly used features of Activity Monitor, a kind of task manager that allows you see how apps and other processes are affecting your CPU, memory, energy, disk, and network usage.
Open Activity Monitor from the Utilities folder of your Applications folder, or use Spotlight to find it.
Overview
The processes shown in Activity Monitor can be user apps, system apps used by macOS, or invisible background processes. Use the five category tabs at the top of the Activity Monitor window to see how processes are affecting your Mac in each category.
Add or remove columns in each of these panes by choosing View > Columns from the menu bar. The View menu also allows you to choose which processes are shown in each pane:
CPU
The CPU pane shows how processes are affecting CPU (processor) activity:
Click the top of the “% CPU” column to sort by the percentage of CPU capability used by each process. This information and the information in the Energy pane can help identify processes that are affecting Mac performance, battery runtime, temperature, and fan activity.
More information is available at the bottom of the CPU pane:
You can also see CPU or GPU usage in a separate window or in the Dock:
Memory
The Memory pane shows information about how memory is being used:
More information is available at the bottom of the Memory pane:
For more information about memory management, refer to the Apple Developer website.
Energy
The Energy pane shows overall energy use and the energy used by each app:
More information is available at the bottom of the Energy pane:
As energy use increases, the length of time that a Mac can operate on battery power decreases. If the battery life of your portable Mac is shorter than usual, you can use the Avg Energy Impact column to find apps that have been using the most energy recently. Quit those apps if you don't need them, or contact the developer of the app if you notice that the app's energy use remains high even when the app doesn't appear to be doing anything.
Disk
The Disk pane shows the amount of data that each process has read from your disk and written to your disk. It also shows 'reads in' and 'writes out' (IO), which is the number of times that your Mac accesses the disk to read and write data.
The information at the bottom of the Disk pane shows total disk activity across all processes. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The graph also includes a pop-up menu to switch between showing IO or data as a unit of measurement. The color blue shows either the number of reads per second or the amount of data read per second. The color red shows either the number of writes out per second or the amount of data written per second.
To show a graph of disk activity in your Dock, choose View > Dock Icon > Show Disk Activity.
Network
The Network pane shows how much data your Mac is sending or receiving over your network. Use this information to identify which processes are sending or receiving the most data.
The information at the bottom of the Network pane shows total network activity across all apps. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The graph also includes a pop-up menu to switch between showing packets or data as a unit of measurement. The color blue shows either the number of packets received per second or the amount of data received per second. The color red shows either the number of packets sent per second or the amount of data sent per second.
To show a graph of network usage in your Dock, choose View > Dock Icon > Show Network Usage.
Cache
In macOS High Sierra 10.13.4 or later, Activity Monitor shows the Cache pane when Content Caching is enabled in the Sharing pane of System Preferences. The Cache pane shows how much cached content that local networked devices have uploaded, downloaded, or dropped over time.
Use the Maximum Cache Pressure information to learn whether to adjust Content Caching settings to provide more disk space to the cache. Lower cache pressure is better. Learn more about cache activity.
The graph at the bottom shows total caching activity over time. Choose from the pop-up menu above the graph to change the interval: last hour, 24 hours, 7 days, or 30 days.
