How to Utilize Activity Monitor to Troubleshoot Problems on a Mac
Posted on February 13th, 2021 past 
We never like to have problems with our computers, but they are inevitable. Sometimes some of your apps don't work, your Mac gets slow, yous get a spinning beachball, and more. Narrowing down the cause of such issues tin exist difficult; fortunately, macOS offers some troubleshooting tools y'all tin can utilise to diagnose what ails your computer.
One of the tools you can utilize to troubleshoot problems on a Mac is Activeness Monitor, a dashboard for many of your Mac'south under-the-hood activities. In this article, I'm going to introduce you to Action Monitor, and explain how this utility tin help you find—and, in some cases, resolve—problems on your Mac.
Where is the Activity Monitor on a Mac?
To find Activity Monitor on a Mac, go to your Applications folder >Utilities binder, and then double-click Activity Monitor. There you lot'll run into a unproblematic app with five tabs, and a list of entries that changes every few seconds.
Each of the v tabs inside Activity Monitor continue track of certain aspects of your Mac'south functioning. Thy are CPU, Memory, Energy, Disk, and Network, and, if your Mac is running the content caching service, you'll as well see a Enshroud tab. I'll discuss what you lot can meet on each of these tabs and how they might be useful when diagnosing problems on a Mac.
The CPU Tab
The CPU tab shows how your Mac's processor(s) are working. In the above screenshot, I've sorted the listing by % CPU, or the pct of the full available CPU time. You may see apps or processes that are using more than 100% of CPU time; this is considering a Mac with multiple cores (all new Macs) count each cadre as 100%.
This tab lets you know which apps are working the hardest. If, for example, the fan on your Mac becomes loud, or yous run into the battery on your laptop depleting quickly, check the CPU tab to see which apps are taxing the processor. In some cases, these may be runaway apps that are stuck.
If you lot find an app that'southward non running correctly—or ane that shows in red, with the words "Non Responding" after it—click that app'south or procedure's name, and then click the X button in the toolbar. Action Monitor will ask if y'all are sure you want to quit this process. If you click Quit, it will attempt to quit the app in the normal style. If this doesn't work, click Force Quit, and, in almost all cases, Action Monitor will be able to quit the app, removing the offending laggard.
The Memory Tab
This tab gives you an idea of how much RAM your apps are using.
Yous tin can notice the nearly RAM-hungry apps, and, if your Mac is running slowly, you tin choose to quit them. You may even want to find replacements for apps that regularly max out your RAM.
Also check the bottom department, where you see Swap Used. Bandy files are virtual retentiveness files that are written to your Mac's disk. Reading retention data from these is much slower than reading from RAM, and if there is a large amount of swap space used, your Mac will run slowly. This is a good indication that it's time to restart your computer.
If after a system restart you notice that your Mac is even so running slowly, have a wait at our in-depth guide on how to fix your Mac's performance issues.
The Energy Tab
The Free energy tab tells you which apps and processes use the most ability. For a desktop Mac, this isn't very important, merely if you're seeing poor battery life on a laptop, this is the place to check.
The Energy Bear upon column updates regularly, and information technology shows the current power usage, but this varies a neat deal depending in which apps y'all use. The near important cavalcade is 12 60 minutes Power. This shows which apps utilize the about power over the past twelve hours, including time when your Mac was asleep. If your laptop'south battery life is insufficient, check here to meet if you're using an app that'due south depleting the battery. This tin be a good way of deciding which spider web browser to use on your laptop. You might try using, say, Safari, Firefox, and Chrome, each for a few days, to see which i uses the least corporeality of power.
The Deejay Tab
Most users don't need to worry most the Disk tab. This shows how much data is being written to and read from your Mac's drives.
Reading from and writing to a disk also uses power, so if y'all run into a lot of disk activity, and your battery isn't lasting as long as you expect, have a look at which apps are doing this. 1 process that may show a lot of activity is cloudd, which is the background procedure that handles reading and writing data from iCloud. If this number is high, information technology could be considering you downloaded a lot of music or movies, added a lot of photos to your Photos library, or you lot have worked on a lot of files in iCloud Drive.
The Network Tab
This tab shows how much data is entering and leaving your Mac over its network interfaces for active apps and processes. You tin can sort by Sent Bytes, Rcvd Bytes, Sent Packets, or Rcvd Packets.
If you accept trouble accessing the Internet, there can exist numerous causes. Some have to practise with your connectedness, but your network access tin as well tiresome downward if there's a lot of data coming into or leaving your Mac. For instance, your upstream bandwidth is most likely lower than your downstream bandwidth. If the former is saturated, you'll notice that even loading simple web pages tin can be painful.
Merely don't just look at those Sent Bytes or Rcvd Bytes columns; they show totals since the last fourth dimension you launched each app or the concluding time yous restarted your Mac, for system processes. Instead, focus on the information displayed at the bottom right, at Data received/sec and Information sent/sec. Those numbers will give y'all an thought if you're sending or receiving a lot of data. You can then check the totals past app, and monitor them to see if they increase. Check the Sent Bytes to see if your upstream bandwidth is beingness used, and your Rcvd Bytes to see if downstream bandwidth is used.
Note that if you desire to find out if at that place's any backlog information usage for Safari, this data is listed nether the procedure Safari Networking, not the Safari app itself. If yous want to focus on a specific app or process, you tin narrow downwardly the display past typing the name of the process in the search field.
While it'due south easy to see what'south using data amongst apps that access the Internet, don't forget that you'll see a lot of data being moved across your local network if yous accept more than one computer and transfer files between them. The Network pane shows all your network activeness, not simply to and from the Internet. If, for instance, you take Time Machine backups going to a network server, so you lot'll encounter a lot of data sent and received here.
The Enshroud Tab
If your Mac is running the content caching service, which can save you bandwidth past storing copies of content yous download from Apple's servers, you'll encounter a sixth tab: Cache. This tab shows how much data has been served, cached, etc. Meet this article for more on content caching.
Activeness Monitor is only i of the useful tools on a Mac that can help you lot troubleshoot problems and go along your reckoner running smoothly. Become to know it so when you demand to troubleshoot you can find some pertinent information virtually how your Mac is running.
