Mac Running Slow? 10 Tips to Speed It Up

1. Use Activity Monitor to identify Memory Hogs

The Activity Monitor provides a convenient way to check which apps are consuming most system resources. You can access it through FinderApplicationsUtilities → Activity Monitor, or open Spotlight by pressing the Command and space bar keys and then type in ‘Activity Monitor.’

In Activity Monitor Menu Click on View and Select Windowed Processes

Now, click on the CPU button in Activity Monitor and the “%CPU” column. This will list all apps according to the amount of CPU they are using. If you notice that any specific app is hogging a lot of CPU power, then you can close it by clicking on it in the list and then clicking the x button in the left corner of the Activity Monitor.

In CPU Tab Select App and Click on X icon

Also, note that if some apps are using a lot of power, it may be time to update them so that they can function more efficiently.

2. Prefer Safari over other browsers

Many apps can be a drain on your Mac, but Google Chrome is especially notorious. Even though it may be your favorite browser, there’s no denying that it hogs more RAM and processing power than others.

Therefore, it’s recommended that you use Safari or Firefox to keep your Mac running fast. Another option is to only open a few tabs in Chrome at a time, but you will need to check if this makes much of a difference.

3. Close Unnecessary Apps

Running a lot of different apps at once consumes plenty of memory and power. So it’s a good practice to close the apps that you’re not actively using. A quick way to see which apps are open is to check the Dock on your Mac. Open apps have a dot under their icon. To shut down an unwanted app, right-click on its icon in the Dock and select Quit or ‘Force Quit’ if you see the option.

Right Click on App and Click on Quit

Alternatively, if you press Cmd + Tab, you can access the App Switcher and see all open programs. As you tab through them, you can select an app and press Cmd-Q to quit it.

If you’re not able to quit the app and only see the colorful spinning ball, you can close apps from the Apple menu. Click on the Apple logo at the left corner of the menu bar and then click on Force Quit.

You will then see a list of all open applications, from which you can select which to quit.

Click on Go and Then Select Go to Folder on Mac

In the Go To Folder box, type in: ~/Library/Caches/

The more RAM that you have on your Mac, the more windows or tabs you can keep running without slowing down the system. The standard RAM on most Macs in 2020 is 8 GB or more. You can check the RAM on your system by clicking on the Apple icon in the menu bar, selecting About This Mac, and clicking on the Memory tab.

You should consult a professional to work out if it’s possible to add more RAM to your system and how much to add.
