How to Fix High CPU Usage on macOS 10.15

High CPU usage on your Mac shows there’re a number of issues with your device. When an app takes up a chunk of your processor there’s a possibility the issue is more than you can handle. To fix high CPU usage on macOS 10.15 Catalina more than one action might be required. Sometimes adware or virus could have infected your CPU and you must fix high CPU usage even without apps running. Having downloaded and installed a new macOS you expect to enjoy the benefits of new apps and tools and not Mac problems that can be debilitating to your work. Here are ways to fix problem when showing high CPU usage on macOS 10.15 Catalina.

Why is My CPU Usage so High

Once you’ve installed macOS Catalina it’s possible to experience high CPU usage that in turn results in slow Mac, high heat generation, lots of noise as fans move in high speeds among others. One of the main reasons is the installation of third-party applications and programs and their automatic launch while booting up your Mac. If you’ve so many of these applications loading up at start you can be sure your Mac will slow down. Even worse, if your device is having problems running 10.15 Catalina you can expect the CPU usage to shoot up slowing your Mac even further.

How to Solve High CPU Usage on macOS 10.15

Any mac experiencing high CPU usage results in an experience you’d love to forget. This includes slowing your device as it labors to process the applications, operating system and other programs. Heat is also generated so much it can be uncomfortable working on your device. High CPU usage could also lead to very fast fan speed that release lots of noise in the process. It means you could take really long to carry out your business with your Mac as other apps and programs take up most of your CPU usage.

How to Fix the High CPU Usage on macOS 10.15 Catalina

It shouldn’t be hard to solve high CPU usage on macOS 10.15.

Monitor the Problem

Start by opening up the Activity Monitor on your Mac, which is equivalent to the Task Manager on Windows. Activity Monitor is the ultimate CPU monitoring software on macOS 10.15 Catalina accessed by going to “Applications” and then” Utilities”. You can also use Spotlight and enter “Cmd + Space” before adding ‘activity’ by typing it in. both should take you to Activity Monitor.

monitor the problem

Note that the reason why your Mac maybe slowing down due to high CPU usage will be very clear. On the CPU tab find %CPU header column to ensure the running processes are organized by the amount of processor they’re using. All the high processor power consumers will be evident from the top.

It’s also worth noting that high CPU usage isn’t a problem per se but only debilitating if you don’t expect it. Of course you expect your Mac to use some resources up while carrying out tasks like watching movies, playing games or editing music or video. However, if a single app such as Safari or other process on your device is using so much then there’s definitely something wrong.

Find the Culprit

On the Activity Monitor’s header column opened start your search for processes running your Mac to disturbing levels. In most cases the problem would be any with 99 to 100 percent usage with perhaps other programs close to 50 percent and above. Do expect that most video and music editing programs will process at 100 percent, particularly while recording, rendering or even encoding. Each of these apps is created to completely make the most of your processor anyway.

Note the Problematic Process

Once you’ve checked the problem that’s misbehaving and known it go ahead and note it somewhere. Later on when you want to ensure the high usage doesn’t happen again the name of the process will come in handy.

Quit the Problem

On the Activity Monitor do pick the problematic program. Select “Quit Process” and confirm you intend to force quit it. Note that by force-quitting it’s possible the app will lose all unsaved information. Also, if system processes are force-quitted your Mac might stop working until you restart.

Troubleshooting the Problem

It’s important to decide how you intend to troubleshoot the problematic process. If you’ve no idea what the process is used for and why it’s important, do a simple web search to understand it before you force-quit or after. Knowing the use of the process helps a lot, including the different things you need to do to stop it from high CPU usage, especially at 100 percent.

Deal with high CPU usage propagated by a specific program or app by:

  • Uninstalling, particularly if you can do without the program.
  • Applying update or reinstalling problematic apps could actually fix bugs and software issues.
  • At times a program you use often activated when your start your Mac could be the issue, slowing down your Mac. Simply remove the app from startup and ensure it doesn’t start when you start your device.
  • Viruses might be uncommon for Mac devices but not completely unheard of. Do malware, adware and virus scans on the Mac to remove them; they really strain CPUs.

Desktop Files

One of the reasons for high CPU usage is due to certain files such as video and image files on your desktop. Preview desktop files and if you’ve so many chances are they’re the reason your Mac has been slowing down. Create a folder on the desktop and place all the media files there. The only time you’ll experience high CPU usage will be when you open the media folder.

Trouble with Most Programs

If high CPU usage is so prevalent and some tools, apps and programs on your Mac aren’t the culprit it’s time to try another method. Think about hardware upgrade such as RAM to enhance performance. RAM is capable of releasing some strain from the processor even in Macs.

It’s also critical to invest in a free CPU temperature monitor for your Mac to keep tabs on temperature and all system fan speeds. Next time you determine unusually high fan speeds on your Mac you’ll only need to check the temperature. If above 60C then look into it; such high temperature are dangerous for your computer in the long run.
