Why your Mac is slow and how to fix it



You used a Mac so you know (and fear) the spinning beach ball of fear all too well when your system crawls slowly. Inevitably, your Mac slows down as soon as you have a big appointment or a heavy workload. There is never a good time to have a slow computer. (Hopefully, Apple's newly announced $ 6,000 Mac Pro will have enough raw power to avoid this chaotic business.)

Yes, you could twist your eyes and learn to deal with frequent slowdowns, but it It's Better to Take It It's time to identify and fix the problem of your MacBook Air or MacBook Pro ̵

1; or at least get it started again. We guide you through the most popular apps that consume system resources, identify which apps are to blame, and give you the best tips to keep your Mac running as smoothly as possible.

Your browser is (probably) the biggest culprit.

Almost any app can affect the performance and memory of your Mac, resulting in slow performance. However, some apps are more likely to crawl your system than others. If you're using Google Chrome, you probably already know that it's usually at the top of the list. As the photographer Christopher Michel discovered Google's backup and sync app can also be a burden.

No one wants a slow Mac. Nobody.

Image or video editing apps like iMovie or Photoshop are also resource intensive. There is no way round it, because the computing power required to render large image files or encode video files is very high on almost all systems.

If you think Google Chrome is too annoying for your Mac, you can switch to another browser, such as Safari or Firefox. Firefox has been working hard on its Quantum version of its browser with the latest update improving the speed of websites like Google, Instagram or Amazon by up to 80%. If you simply can not give up your browser, you may need to adjust your workflow. Instead of opening 15 tabs at a time, limit yourself to 7 and learn to close older tabs diligently.

For image and video editing apps, you can try different apps, such as: GIMP, which are designed for a wider range of systems with minimal specifications and therefore require fewer resources. Remember, but you can lose quality to get a little more power from your Mac.

Before you move up your favorite apps, you need to find out which ones are slowing down your Mac. To do this, you need to familiarize yourself with Activity Monitor.

Activity Monitor indicates that the apps are slowing you down.

Activity Monitor is integrated with MacOS and is located under Applications> Utilities. When you open Activity Monitor for the first time, the CPU tab is selected. You'll see a list of the apps and processes that are running, and every few seconds the list will be rearranged. There are some familiar names and other processes, such as WindowServer, that are most likely unknown.

To get a clear picture of what to do, click the "% CPU" drop-down list to arrange the processes for the highest CPU usage.

After you've ordered the processes for the highest percentage of CPU utilization, watch them for a few minutes without doing anything on your Mac. Your Mac is constantly performing tasks in the background, so the processes continue to be moved up and down the list. Sometimes processes jump over 100 percent for a brief moment before going back to a lower number. Whatever your system weighs, it should always be high on the list.

It's best to look at Activity Monitor for several minutes to see what's bothering your system.

For example, I recently saw a "Google Chrome Helper" process running at 20% to 25% CPU utilization on running processes. I was not sure what Google Chrome Helper is, but I knew that several processes were running with that name. After some research, I found that it could be a Chrome extension or an open tab. It just happened that there were about 40 tabs in Chrome, so I started closing each tab one by one until the resource hogging process disappeared from my activity monitor.

You have various ways to deal with rogue app or process after you have identified it. You can either fix bugs by closing each tab, window, or application until you find it out, or you can highlight it in the Activity Monitor and click the stop button with an "X".

You are asked if you want to stop or force the operation. Start with "Quit" and click on the same button to reduce CPU usage. Then choose Force Exit.

Back to basics

There will be times when you open Activity Monitor and find that "kernel_task" or "launchd" or even "WindowServer" consume all the resources of your Mac. These processes are quite vague and can not be linked directly to a particular app running on your Mac.

In these cases, it's a good idea to return to the obvious troubleshooting tips that we all can sometimes overlook. You could very well make a difference.

  • Quit all open apps. In addition to closing the windows, right-click on the App icon in the Dock and select "Exit".
  • Restart your Mac completely. Instead of choosing Restart from the Apple menu, select Shutdown and give your Mac a few minutes to turn it off completely – and turn it back on.
  • If you find a specific app, your speed will always slow down Adjust your workflow to use this app without having anything else open on your system and stop the app when you're done.

There are other issues that can affect the performance of your Mac. Things like random logons, insufficient disk space, or old apps that you no longer use may degrade performance.
