CleanMyMac Guide – How to Reduce System Storage on Mac?
Is your Mac
running out of storage space? Are you unable to save new files on your system because of it? Learn how to reduce system storage on Mac
and make more space available.
First, let us see how much space has been used up by the system. Click the Apple logo on the top left corner of your screen and choose “About This Mac.” Click on “Storage,” and a window will pop up showing you the storage usage. If the bar is yellow, then a lot of space has been used up. If more than 50% of your total storage is occupied, you will have to clean your system up. You can do this by learning how to reduce system storage on Mac.
Sometimes, it becomes even more frustrating when you are unable to figure out what exactly is taking up so much space. Click on “Manage” and you will get a window
displaying System information. The “System” option on the left panel will mostly be greyed out, so you have no way of knowing what is wrong.
The reason why “System” is greyed out is so that you cannot access it and accidentally delete important system files on your Mac
. So how do you manage your storage space? Let us look at some ways of how to reduce system storage on Mac
Third-party app: CleanMyMac
The “System” category under System information contains several files like video
backup files, etc. You cannot delete them manually so you need to make use of a third-party app
. One of the best system clean-up apps is CleanMyMac
that we will discuss here. You may try other similar apps.
, a feature called “Space Lens” allows you to see the data
inside the “System” category and how much space they are taking up. Follow these steps:
Even after using a third-party app
, not much space may be freed up. So if you still need more ways of how to reduce system storage on Mac
, here are some other methods you can try:
1. Delete/move large files manually
Open a Finder window
on your Mac
and choose the “Recents” folder
. Sort all your recent files by size – big to small. You can click on the Settings icon and go to Arrange By > Size. You will see at one glance which files are taking up too much space.
Choose the ones you do not need and delete them, or archive them into a cloud service
. You may want to move them to external storage, but ensure that they do not lie on your Mac
eating up large chunks of storage.
2. Delete duplicate files
It is quite common for duplicate files and similar files to pile up inside your system. You are not even aware of them as they slowly take up too much of your storage space.
Use a third-party app
like Gemini 2
to scan your most-used folders to find such rogue duplicates. Once you review
them and confirm, these duplicate files will be deleted
from your system.
Now that you know how to reduce system storage on Mac
, you should keep in mind that it is advisable not to get to the stage where you need to free
up space. Use Apple
’s “Optimized Storage” feature to have your data
backed up into the cloud
. Thus your system will always have enough space to run your programs freely and save new files.
