how to clear system storage files on Mac

Remembering to clear your Mac computer’s storage system is a huge part of good housekeeping if you want to keep your Macbook’s performance healthy.

Over time, your Mac’s hard drive can fill up with old temporary files, software driver caches, logs, and other detritus software updates that won’t be used again until the end of time.

This isn’t usually a problem for most users but it can slow down how your Mac works if there are too many files clogging up the storage system.

The challenge for most Mac computer owners is knowing how to clear storage space on their Macbook computers.

As a general guide, storage systems on Mac computers can be cleared out of outdated files using terminal commands and special software applications widely used to keep your Macbook computer SSD clean and at optimum performance.

The solution? We’ll show you how to clear storage space on your Mac in this article. Read on to find out more.

What Is System Storage On Mac?

System storage on Macs or on HP Chromebooks is the part of memory that stores what are known as system files. If you have a Mac computer with an SSD drive, then these are typically located at the top of the drive.

If you have a Mac with a hard drive, then you will find system files towards the bottom of the drive-in an area known as the System Reserved Partition. These files are all that’s needed for your Mac to work.

How To Clear System Storage On Mac?

There are two ways to clear system storage on your Mac which we will talk about in this article. You can either use a separate program to do the job or you can manually clear system storage on Mac using nothing but good old-fashioned Terminal commands.

Clearing The Storage For A Single App Using CleanMyMac

One of the best ways to make sure your Mac stays healthy is to clear storage space on it from time to time. In this section of the article, we’ll look at how you can use CleanMyMac as a tool for removing unnecessary files from your Mac’s system storage.

While Cleanmymac software won’t do away with all of the clutter inside your Macbook computer, it does offer a solution that’s quick, easy to use, and relatively straightforward.

Cleanmymac is an app designed for this specific purpose—to clear out junk files from your Mac computer. It will scan your hard drive in search of unnecessary files, find them all, and then delete them in order to free up space on the storage system.

CleanMyMac is easy to download, install, and use. After you download the app, you simply need to click on the Scan button in order to get started. Once Cleanmymac has run its scan, it will present a list of files that are cluttering up your system’s memory.

Since it’s not always obvious what these files do, CleanMyMac has a section that explains how important certain files are to the operation of your system.

For example, if you click on an application file, you’ll see what software it works with and what purpose it serves. You can then make an informed decision about whether or not you want to keep the file or delete it completely.

One thing to keep in mind when you’re using CleanMyMac for this purpose is that it will take up some of your Mac’s storage space. This means you should use it only every now and again because the more files you delete, the less free space you’ll have left on your hard drive.

To give yourself a bit more room, click on the total amount of space that’s being used by all the files in the list and then select to delete them all. You can always use CleanMyMac at a later date to get rid of any leftover files.

How To Clear One App From System Storage Using Terminal Commands

Terminal commands is the most widely used for Macbook owners who want to clear out unwanted files on their mac manual. Typically, if you don’t want to use an app to clean out your Mac memory, then terminal commands is going to be the next best option for you.

While there are a few different Terminal Commands that can be used to clear system storage on Mac, we’re going to focus on just two of them here:

One for deleting a single app and another for deleting all apps at once.

You can use these two commands when you want to clear the storage space from a single app or all apps that are cluttering up your system’s memory.


The first command is going to delete a single application from your Macbook. This will free up some of your system’s storage just as any other app would, but it does have one downside: You won’t be able to use the app again until you reinstall it.

Use this command when you want to delete a single application from your system, but still want to keep all of your other apps:

sudo rm -rf /Applications/”app name”

So for example, if we wanted to delete an app named “VLC,” we’d type in:


sudo rm -rf /Applications/vlc/

This command essentially tells your Mac, “Hey, I want you to delete VLC from my system.” Make sure the app name matches the one you’re trying to remove. If it doesn’t, you won’t be able to use this command.


The next command is used when you want to delete all of your Mac’s apps at once, freeing up as much storage space as possible. Just like before, make sure the app names match whatever it is that you’re trying to remove. If the wrong app name is used, then this won’t work.


sudo rm -rf /

So for example, if we wanted to delete all apps from our system at once, we’d type in:


sudo rm -rf /

This is a really quick and easy way of clearing out your Mac’s memory. However, you won’t be able to use any of your apps until you reinstall them, so it’s a good idea to only use this command when you know you won’t need any of your apps for a while.

The last thing I want to mention before moving on is that these commands are going to delete files from your system without actually notifying you about what they’ve done. This means you should only use them to delete system files and never for personal files, as those might be deleted as well.


Taking time to free up storage space on your Mac computer is a really good idea. You can do this with CleanMyMac or by using Terminal commands to clean system storage and free up the storage space your Mac needs.

There are pros and cons to both methods widely used to free up storage space on Mac, but the bottom line is you’ll get a lot more space back when you delete files from your system than if you were to let them stay there.
