macOS Big Sur brings the big update that makes you want to install it for sure. The OS has not officially released yet, but the public beta version is available to test. Though, waiting for the final version is most advised. However, compatibility and storage availability are two things you should check in the first place before updating macOS. You will need at least 30GB available on your Mac storage for Big Sur. Otherwise, the downloading process won’t run and the installer will ask you to free up space on Mac for macOS Big Sure update. This is what we are going to discuss here. So, let’s dive in.

How To Free Up Space On Mac For macOS Big Sur Update
To make sure you have enough space on your Mac computer, simply click the Apple menu on the left corner of the screen, and click About This Mac. Then, select Storage. If your Mac is running out of space, use one of these methods to free up your Mac storage.
The first thing that comes to your mind when it comes to free up storage is probably emptying the Trash. Simply click the trash icon on the dock, click the Empty button on the upper screen. However, this method may only contribute a few hundred MB or less.
Uninstall The Unnecessary Apps
You may get 5 GB free from your Mac storage by deleting the apps. However, to remove the app completely from Mac you need to uninstall it using a third-party tool. Dragging it to the trash may still leave some parts of the app.
To uninstall the apps from your Mac completely you can use a third-party tool like CleanMyMac X. Yes, it is the latest version CleanMyMac 3. If you already have the old version, you can use it as well, but I suggest you upgrade to the new version. It comes with a major upgrade and new features, such as Malware Removal and Updater.
- Download and install CleanMyMac X on your Mac.
- Launch CleanMyMac X.
- Select the Uninstaller section from the left tab
- Choose one or more apps that you don’t use anymore.
- Click Uninstall.
Try to check the Leftover section as well. You may find some parts of the old apps that you thought have been removed from your Mac forever.
Delete Large Files
When was the last time you cleaned your Mac? You must have a load of files store in your Mac, from videos, documents, eBooks, etc. Finding that kind of files amongst thousands of data on the Mac folder is quite challenging. That’s why it would be better if you start looking for files with the largest sizes.
Launch the Finder on your Mac, choose Desktop, Download, or the other folder. On the upper menu bar, click the settings/ gear icon. Select Arrange By from the drop-down menu, then chooses Size. To delete it, click right the file and click Move to Trash.
For a simpler and easier way, use CleanMyMac X instead. I assume you have downloaded and install the tool on your Mac.
- Launch CleanMyMac X.
- On the left menu, select the Large & Old Files under the Files section
- Click the Scan button
- Choose the files and hit Remove.
Clear System Junk
You may have deleted tons of documents, a bunch of large files, and uninstalled as many apps as you could. But still, the installer said that you don’t have enough space for installing macOS Big Sur. Try to clean the system junk on your Mac. You may be surprised by the result. You will probably release around 2 to 5 GB by doing this. Foremost, if you have never cleaned the junk files on Mac.
To clear system junk on Mac, first open Finder. Then, press the Command + Shift + G buttons altogether and type
~/Library/Caches on the field and click Go. To delete all files at once, press the Command + A buttons.
Alternatively, use CleanMyMac X which is my favorite.
- Open CleanMyMac X.
- Click the System Junk under the Cleanup section.
- Hit the Scan button.
- Click Clean.
Turn Off Time Machine Temporary
Time Machine can store some files from back-ups (local snapshots) to your Mac when the back-up disc is not connected. Therefore, if you are using Time Machine, turn it off temporarily. It can help you to free up space on Mac for the macOS Big Sur update.
- Click the Apple menu and select System Preferences
- Choose Time Machine
- Click the Turn Off/On switch.
Get A Clean Manager Tool For Your Mac
It is recommended to clean up your Mac regularly. It will not only make your computer faster but also ease you in finding certain files. But, it seems like exhausting work. Emptying the trash on your Mac is a piece of cake, but then you have to delete unnecessary files, clean system junk, photo junk, uninstall apps that use different methods. That is what I felt before I met CleanMyMac X.
Once you launch CleanMyMac X on Mac, you can start cleaning the computer by clicking the System Junk > Scan > Clean. Then, go back to the main page and clean the Photo Junk, Mail Attachments, iTunes Junk, and Trash Bins using a similar method in the same place. To remove the unused apps, select the Uninstaller under the Applications section on the left tab.
I have been using CleanMyMac X for MacPaw for a long time and I found it as an effective tool to manage my Mac. You can free up space on Mac, free up RAM, uninstall apps, and else, all in one place. You don’t need to jump from one method to another one to free up large storage. Why complicate something if you can make it simpler. The latest version which is CleanMyMac X even adds the Protections section including the Malware Removal feature. I believe you will love CleanMyMac X too as I do. It makes cleaning up the Mac simple and enjoyable.
