In this term, users have never stepped back instead, plenty of users have stepped into it by installing macOS. Here’s how to Speed Up Slow Running macOS Catalina.

The installing of macOS never ends to Mac users only, but they also belong to Windows users. As users have been doing this from quite past, they are also able to install macOS Catalina on different spots with different methods. The most common and useful one is installing macOS Catalina on virtual machines which are done in two different ways, that are installing macOS Catalina on VMware and installing macOS Catalina on VirtualBox.

Aside from these two, if you’re a Windows user, you could also install macOS Catalina on PC which is straightly installed on PC(Hackintosh) actually and can dual boot with Windows even. For this purpose, first, Catalina Hackintosh bootable USB or create Catalina bootable USB from Windows and make ready your PC by setting up BIOS options and install which we’ll show it all when it’s ready.

Regardless of where you’ve installed Catalina that should function without issues from all edge but it isn’t what it is expected to be. From those who have installed, they’re experiencing a slow performance which isn’t pleasant at all. As the public beta of the OS is near to end but the problem doesn’t seem to be fixed soon.

How to Speed Up Slow Running macOS Catalina

There are several reasons why macOS Catalina would perform slowly. Some of these might be from your system which matters for the performance a lot. But there are also some other stuff installed or running which might slow down the performance. Here’s what you can do about it. We’re taking a look at the performance problem and how to Speed Up Slow Running macOS Catalina

Check If Your Device is Compatible

One of the common reason for slowly performing Catalina might be due to your device is incompatible. If you’ve installed macOS Catalina on a Mac whether it’s MacBook Air or other Apple hardware which was built before 2012 or 2013 in some Macs, unfortunately, it won’t support the Catalina properly. However, if you don’t have an idea about that, but were able to run Mojave, there’s no reason why you can’t install this.

If you’re a Windows user who has installed macOS Catalina, there’s no such a thing for you. In fact, there’s no compatibility problem but it probably means that if your device is older than 2012 or before, it could probably be the reason for low performance since your device has limited and less powerful hardware which could perform Catalina with a high speed. Here’s the complete compatibility list of the devices.

Update Your macOS To The Latest Version

Updates are an important part of the performance and overall things. They’ve a whole benefits that would make things better and easier such as fixing security patches, software or operating system vulnerability, new features, new things and importantly more performance. This is the first part of how to Speed Up Slow Running macOS Catalina.

Since Catalina is continuously updating to minimize the problems and maximize the quality of use, make sure you update to the latest version of macOS Catalina whether you’ve installed on Mac or on a virtual machine on VirtualBox or VMware Workstation Player.

These updates will do their best to make the most flexible and smooth experience ever. However, you can check whether there’s an update or not.

From the System Preferences, head over to Software Update.

System Preferences

On this window, it will check if there’s an update, if available, click on Update Now. From the bottom, you can also check the button to keep your Mac automatically updated. This is great.

Clean Up Your Mac’s Drive

While almost everything stores on the hard drive and even the operating system is installed on, it has a significant effect to the speed of running Catalina. This is a proven and working way to speed up macOS which is even working on Windows 10. On Mac, storage is one of the huge problems which fills up so quickly. As it fills up, it also adds up junk, temporary files which causes slow down the Mac.

What cleaning up your Mac’s drive should do is to remove the unwanted, junk, unused and temporary files. Not all of these could happen within a single task, but first, we’ll get rid of the unused and used files that are no longer needed. By default, macOS Catalina has an optimize storage option, which saves space by removing some unused and old files that you’ve used. Here’s how to Speed Up Slow Running macOS Catalina.

Fire up Apple menu from the top left corner of your screen and click on About This Mac.

Apple Menu

Now select Storage >  Manage.


There, click on Optimize from the Optimise Storage.

Optimize Storage

However, there are also some more options which are quite useful. I recommend utilizing these options that will certainly work. The first one is the Store in iCloud which helps you store your files in iCloud account that will free up some handful of space. The empty trash option will automatically erase everything from the trash.  The next and effective one is Reduce Clutter that enables you to review your files and delete what’s no longer required.

Clean-Up System By Getting Rid of Junk Files

As we cleaned up the system from unused and not needed files, we will clean up the system from junk files. If you don’t have an idea of what are Junk files – Junk Files are temporary files such as cache, temporary files that are created by running programs or apps. Being many or even less of them could slow down even after you’ve update your Mac.

While deleting junk files are easy but figuring out and doing is manually requires much time. But there are some apps which could do this for you. However, for clearing the cache, I’ve the solid idea of removing it.

Head over to Go from the top menu and click on Go to Folder.

Go to Folder

Now go to ~/library/caches/ and press Enter.

Go to Folder

When the cache window opened, it will show up the caches folder, delete everything there. When you’ve deleted those, they will be in trash. Don’t empty trash quickly, just for caution if something goes wrong.

Move to Bin

Afterward, reboot your Mac to let your Mac begin making caches and working properly.

This should improve the performance because your Mac has now more space and no useless files to fiddle with.

Organize Start-up Items

Starting a computer should take a minute or two but that doesn’t always happen. Whether you’ve installed Catalina on Mac or virtual machine, no matter wherever you’ve installed, it should boot up quickly. But when it doesn’t, there’s a scenario. If you’re assuming this due to little powerful hardware, that’s only a tiny cause. The other side of this problem refers to the start-up items that are launching up automatically. Doesn’t matter whether the app is small or huge, but it will slow down the start-up since they will begin to launch before Mac has properly been prepared for.

Start the System Preferences from the dock in the menu then select users & groups.

Users & Groups

Select your user account and click on login items. From here, select the programs you want to disable opening, (they are enabled), tick the boxes and click on the – icon from the bottom.

Login Items

Remove Used, Unnecessary Apps & Files That Are No Longer Needed

The obvious but most forgettable step for speeding up running macOS Catalina is to uninstall used, unnecessary apps and files that are no longer needed. When they are installed, even when they aren’t running, they will likely consume some power, system’s resources and space which is likely to slow down your Mac. One of the simple examples is the downloads folder. As it’s my tendency that whenever I download things and use it, afterward, I simply forget to delete those.

This example also applies to apps. There are probably some or many apps that you’ve installed but don’t need anymore. In this case, deleting them will free up space and won’t run anymore in background. So uninstalling an app is easy and removing unnecessary files are easy too.

There are several ways you can uninstall an app, we’ll do it in a simple step.

Goto Finder and open Applications folder. Now right-click on an app you wish to delete and click Move to trash.

Stop Running Apps or Programs From Background

Often there are some apps which aren’t actually running but uses system resources sometimes. These apps or programs utilize a system’s RAM, processor, and overall resources. That doesn’t only limits to apps, but they can be programs, services and other things. Like Outlook which runs at the background of your system and utilizes all those resources and you can’t figure out them from the desktop but from the Activity Monitor.

As a result, they will slow down the Mac even when you’ve done all those steps above. Just like you do on Windows with the Task Manager, closing them is pretty straightforward. Here’s how I do it.

Open Spotlight and write Activity Monitor then hit Enter.


Now select the app or service you would like to close then click

Activity Monitor

Manage The User Interface Visual Effects

With the macOS Catalina update, Apple’s has definitely improved up the user interface but that would obviously use some power, resources but mostly video memory which will end up making slow your Mac. These effects are optional and can be turned down which we could do straightly from the Mac.

Goto System Preferences and click on Accessibility.

System Preferences

Now select the Display option disable the Reduce Motion and Reduce Transparency.
