Fix macOS Big Sur Slow Performance in General

Once, you’ve installed macOS Big Sur or any other versions of macOS on your system. You’ll see that your macOS is very slow and you’re not able to do your work as smoothly as you wished to do. Now, I’ll show you some general performance tips that might help you to speed up your macOS.

#1. Check Compatibility Issue

First, you need to check if your system is compatible with macOS new version or No. If you’re not sure that your device is compatible with the latest version of macOS then check the following system compatibility lists.

Macs compatible with macOS Big Sur – macOS 11:

• 2015 and later MacBook
• 2013 and later MacBook Air
• Late 2013 and later MacBook Pro
• 2014 and later iMac
• 2017 and later iMac Pro
• 2014 and later Mac mini
• 2013 and later Mac Pro

And Accordingly, the following models capable of running macOS Catalina will not be able to be upgraded to macOS Big Sur:

• 2012 and Early 2013 MacBook Pro
• 2012 MacBook Air
• 2012 and 2013 iMac
• 2012 Mac mini

If you need to see more about the compatibility list head over to Apple support.

#2. Update your macOS to the Latest Version

If your system is compatible with macOS latest version, you should upgrade to the latest version. Because the latest version is most often better than previous versions due to bug and performance fixes.

#3. Quit Starting Applications

When you start your Mac, a lot of things load up in the background. Not only do they slow down your startup, but they continue to do so the whole time you’re on your Mac device.

You can get a fast macOS startup by removing unnecessary apps. To turn off Login Items go to your System Preferences > Users & Groups and then click on your username. Now, click on Login Items, click on the name of an application you don’t need to launch during startup, and then click the “-“ symbol located below the list to the left; this will remove the application from the list. The fewer applications on the list, the better. This should help out a ton with speeding up your slow macOS.

#4. Stop Background Running Apps

When you’ve got too many running applications in the background, your macOS can’t even handle simple tasks that cause slow performance. If you want to have speed macOS then you need to stop and quit background running apps.

Activity Monitor will show you what processes are using up your system resources. Quitting an unnecessary app that’s taking up a lot of processing power could make a huge difference in speeding up your slow Mac. Open up your Applications folder and then your Utility folder. Here you’ll find the Activity Monitor, open it. Check out the list of apps and processes that happening on your Mac system in real-time.

From here, you can see what’s causing trouble with your Mac. Click on the Memory tab at the top, then the Memory filter at the top of the list; this sorts the programs by the amount of space they’re taking up on your Mac RAM. The higher the number, the more power they need. Stop an app from operating by clicking on the app in the list and then clicking the gray “x” icon located at the top-left corner of the window. Don’t remove anything you don’t know!

#5. Uninstall Unused Apps

Most of us download applications that seem helpful and exciting at first but turn to clutter up our disk instead of being used frequently. Unused apps are the biggest space-wasters on our system. So to get rid of those or at least honestly tell yourself which ones you don’t use anymore.

• Go to Finder and navigate to the Go menu.
• From the drop-down list, select Applications.
• You will see all applications installed on your system.
• Right-click on the app that you don’t normally use it. Select Move to Bin or Trush.

Uninstall Unused Apps

#6. Remove Outdated Cached & Junk Files

There are various types of cached files on your system such as; system cache, user cache, app-generated cache, and more. These cache files are one of the cause that slow down you macOS so you should remove these files frequently. To remove cached files, follow the steps below.

Note: This step can be risky because you might delete not outdated files so be gentle with deleting the files. At least take a backup of the file you’re trying to permanently delete. Just in case something went wrong, you should have the backup to replace it with the corrupted folder.

• Open Finder and click “Go to Folder” in the Go menu.
• Type in /Library/Caches and press Enter or click Go
• Locate a cache folder tree
• Go into each folder and delete its contents
• Empty the Trash bin

Note: The following research has been done by one of our website visitors (Jordan Van Bergen). The following steps might not be helpful for those who using Windows Hyper as their virtualization software.

After getting it to work with VMWare I tried booting my Catalina version on Virtualbox but this really doesn’t start at all and is very slow as well. I have the Windows10 May Update. Windows 10 – Version 2004 OS Build 19041.329

So it could well be that everything depending on VirtualBox doesn’t work as it should due to the Windows 10 may update. BlueStacks Android emulator doesn’t work any longer as well due to the May Update.

Virtualbox Mac Os Slow

So I found this as well: https://dev.to/bobnadler/virtualbox-6-1-x-windows-10-2004-upgrade-problem-resolution-4i39

So a lot is not functioning 100% after Windows 10 – Version 2004 OS Build 19041.329 with VirtualBox.

I had to do this: It’s due to the Windows 10 Version 2004 May Update! If you do the following as long as you have the same issues then it will work again:

#1. Navigate to Control panel -> Programs and Features -> Turn Windows Features on or off -> Uncheck Hyper-V and Windows Hyper-Visor Platform.

Uncheck Windows Hyper-V

Additional Notes for Windows Hosts

#2. To check the status of Hyper-v in Windows 10. Open Run and type OptionalFeatures.exe. Look for the “Hyper-V” option. The box should be empty, not checked, or shaded. If you want to be absolutely sure that Hyper-v is gone then open an administrator command console and type “bcdedit /set hypervisorlaunchtype off”. Make sure to fully power down and reboot the host after changing the Hyper-v setting.

#3. On some Windows hosts with an EFI BIOS, DeviceGuard or CredentialGuard may be activated by default and interferes with OS-level virtualization apps in the same way that Hyper-v does. These features need to be disabled. On Pro versions of Windows, you can do this using gpedit.msc. Set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard. Turn on Virtualization Based Security to Disabled. CredentialGuard is a subset of DeviceGuard, so disabling the former should be enough. If you cannot use gpedit for some reason then the equivalent registry hack is to find the key HKLM|SYSTEM|CurrentControlSet|Control|DeviceGuard|EnableVirtualizationBasedSecurity|Enabled and set it to 0.

#4. On Win10 hosts, check Windows Defender > Device Security > Core Isolation Details and make sure settings in this panel are turned off. Reboot the host from power down if you needed to make changes. “Core isolation [includes] security features available on your device that use virtualization-based security” which is why they can interfere with VirtualBox.
