Since you have been asking – how to clear disk space on Mac? Let us now take a close look at some of these methods to clear up space on your device. If you don't want to do these manually, all of them can be done easily by PowerMyMac.

1. Remove Duplicate or Similar Files

Duplicate or similar files are notorious for eating up most of your hard drive space. One of the initial tasks that you should focus on is to remove these files, especially if you have been using your computer for a long time.

2. Empty the Trash Cans

The Trash on your device is the equivalent to the Recycle Bin on Windows. Instead of deleting files permanently from within the Finder, they are moved to the Trash so you have the option to restore them later in case you change your mind. If you want to completely remove these files to free up space, you must empty your Trash. Since Macs have several trash cans, you must empty several.

How to clear disk space on Mac by emptying the main Trash? Simply CTRL+click or right-click on the Trash icon that you can find at the right bottom corner of the dock and select Empty Trash. This action will delete all the files you sent to the Trash from the Finder. Remember that iMovie, iPhoto, and Mail have separate trash cans. In case you have deleted media files from these applications, you must empty their trash cans.

3. Uninstall Unused Applications

How to clear disk space on Mac by removing unused apps? Generally, all applications that you installed on your Mac can take up space. It is recommended to uninstall those that you no longer need:

Simply open a Finder window and choose Applications in the sidebar.
Once you find the icon of the application, drag-and-drop to the Trash on your dock.

Remember that some of these applications might be eating up a lot of space. To distinguish which applications are taking up most space:

Open a Finder window and choose Applications.
Tap on “Show items in a list” knob on the toolbar.
Tap on the Size heading to categorize the installed applications based on size.

4. Remove Any Downloads

Some have downloaded files from messengers, web browsers and mail. If you download files from the Internet, you can find them in the Downloads folder.

Generally, it is found in this location:

/Macintosh HD/Users/Current User/Downloads

Based on statistics, an average Mac user can end up with 0.5 GB weekly in the Downloads folder. In most cases, all files in the Downloads folder are left in disarray and eat up precious disk space. It is recommended to sort out the files based on size, date or kind to sift out the unnecessary ones from those that you still need.

5. Clearing the Cache

The cache file is a temporary data file created by browsers, applications, and other programs to allow your Mac to function faster. When cache files are removed, they are recreated once an application is used again. Nevertheless, you might not be using some applications and their leftovers are still in the Cache folder which occupies a lot of disk space. This is the reason why it is recommended to regularly clear the cache.

The cache files are typically stored in the Library folders that you can find in the following locations:

/Library/Caches
~/Library/Caches

In the /Library/Caches, you will find temporary files produced by the system. Generally, these files will not take up too much space. Nevertheless, in the ~/Library/Caches folder, it stores many junk files that are produced when running applications. As a result, this folder increases in size over time.

How to clear disk space on Mac by clearing the caches? Generally, the Library folder is hidden on macOS as Apple. You can access it with these steps.

Open the Finder window
On the Menu, tap on Go > Go to Folder
In the dialog box, key in ~/Library/Cache and tap on Go

6. Remove Language Files

The applications in Mac include language files for every language being supported. You have the option to switch the system language of your Mac and start using the apps in that specified language right away. Nevertheless, most are likely to use one language, thus the language files only take up space.

7. Remove Old iPhone Backups

For those who often sync their iPhone with iTunes, the application produces several backup copies on your device. Over time, these files can eat up precious disk space since they usually include music, movies and other large files. You can find these old backup copies by opening iTunes > Go to the Menu Bar > iTunes > Preferences.

You will see a list of all the backups that iTunes managed to produce while working with your device. Once you made up your mind that they are no longer need, you can safely remove them but make sure they are in iCloud.

An alternative approach in finding and removing iOS backups is to go to:

~/Library/Application Support/MobileSync/Backup

8. Cleaning up Large Mail Attachments

If you are using the Mail application in macOS with the same email account for a long time, there is a high chance that large email attachments are taking up a large chunk of space on your drive.

The initial step is to change the Mail settings to not download any attachments automatically to help save space or perform a cleanup task to eliminate them. For those who are using Gmail, you can designate limits on the number of messages synced over IMAP by default to only display the last few thousands instead of everything.

Go to Mail > Preferences > Accounts > Account Information.
Change the drop-down for “Download attachments” to either “Non” or “Recent”.

Altering this setting will allow the Mail app to not use up any more space but this will not deal with the issue of attachments from emails that were already been downloaded.

How do I free up disk space on my Mac by removing these attachments? Just do it manually with the following steps.

Open Mail and tap on the folder that you want to find and remove any attachments.
Utilize the Sort by Size option to find large-sized messages
Tap on the Message and select Message > Remove attachments from the menu bar. Remember that this will not remove the attachment from the mail server if you are using IMAP.
Repeat these steps on all messages that you want to delete attachments from.

9. Clean up Photos

Obviously, if you have a lot of photos on your device, they eat up most of your disk space. Essentially, you can choose those that you can remove such as duplicates or copies are photos mistakenly taken.

Once you have deleted the unwanted photos, the next step is to eliminate the files that your system created. In Photos, it is the cache files while for iPhoto, it is the service copies. Understandably, both are difficult to find but there are ways to do so.

The Photos cache includes the iCloud local copies, Faces cache and other elements related to your apps. How to clear disk space on Mac by deleting photos? For macOS versions earlier than Sierra, simply follow these steps:

Open Finder and proceed to your Photos library
CTRL+click your Photos library and choose the “Show Package Contents” option
Access “resources” and proceed to “model resource”

At this point, you will see several folders in the Finder window. The Photos cache rests in these folders, but it can be tricky which ones are safe to remove and what is not. Remember that removing the wrong file can disrupt the overall performance of Photos.

For those who are still using iPhoto, you must find the service copies it produces every time an image is altered. If you are going to work on this task, simply repeat steps 1 and 2 above. Go through the Master, Modified, Original and Preview folders to decide on which photos have original copies that were altered.

Let's Wrap It Up

Understanding What “Your Disk is Almost Full” Means

What is a startup disk?

A startup disk, as taken from Apple Support article, is a volume or partition of a drive that contains a usable operating system. Still confused? Let’s break it down for you.

Your Mac hard drive consists of disks (or partitions). Each disk (or partition) has your Mac data on it, which consists of your operating system, applications, etc. Most Mac users have just one disk but power users may have two or more.

Let’s look at an example of a Mac with only one hard disk:

Your Mac's hard drive is 500GB.
It has one 'disk' on it, so all 500GB of storage is on that disk.
The disk has an operating system (macOS Big Sur), and user data (apps, etc).
And since you only have one disk, this is your startup disk: all 500GB.

A Mac with two disks will have the storage divided between them. The Mac drive with the OS on it is the startup disk while the other drive is just used for storage of files. It’s possible to have multiple startup disks, but most Macs will only have one. And for proper disk cleanup on Mac, all drives are just as important.

Why your disk is almost full?

This is easy. It’s a lot like why is your fridge full? There is no more space! Your disk is almost full and this is very bad news for any drive. A hard disk should never get beyond 85% capacity (especially a startup disk) as you will experience slowness and errors the further you get above that mark.

If your startup disk is full and you get a message of warning from your Mac, this is a serious indication that you need to clear up storage immediately.

What to do when your disk is almost full?

So how do you fix your almost full startup disk? The same way you solve the problem of a packed fridge - you need to clear up storage, of course. To make more space on your startup disk you will need to:

Delete files from your Mac.
Move files to an external hard drive or cloud storage.
Or install a second internal hard drive on your Mac.

So, now that we know what a startup disk is, we need to talk about how to fix it. Let’s take a closer look at your disk space to see exactly what is causing your disk to be almost full.

What’s Causing 'Your Disk Is Almost Full' Alert?

Short version: Take a look under-the-hood of your Mac.

Before we can see what is taking up space on your startup disk, first we have to find it:

Hover on the Dock at the bottom of your screen and open Finder.
Click on “Finder” in the menu bar at the top of your screen.
Then select “Preferences…”
In the window that opens, checkmark the “Hard disks” checkbox.

After selecting this box, your desktop should now show the hard disks on your Mac, in the form of icon(s), like this:

These are disks on your Mac that you can “startup”, this is because they have operating systems on them. If there is more than one of these hard disk icons that show up on your desktop, it means you’ve got multiple hard disks on your Mac. If you only have one, skip the down to “What is taking up all of my startup disk space?” section.

If you have more than one, continue with the next step:

Click on the Apple icon at the top left of your screen System Preferences > Startup Disk.
Here, again, you’ll find your hard disk(s); they’re probably named something like MainSSD or MainHD. It will also display “OS” and the version number of that OS. If you have more than one OS drive, your startup disk should be the one with the latest version of macOS running on it, but we’re going to make sure of that in the next step.

I only have one and it looks like this:

To make 100% sure that you know what drive is your startup disk, follow these steps:

Click on the Apple Icon in the menu at the top-left of your screen.
Select “About This Mac.”
Under macOS, you’ll find a version number. Mine is 11.01.1, like so:

See how my version number in the “About This Mac” window matches the number in my Startup Disk section? Yep — That’s my startup disk. Found yours? Good.

What is taking up all of my startup disk space?

Now that we’ve identified our startup disk, let’s take a closer look at how to clear up space on Mac:

Click the Apple Icon in the menu at the top-left corner of your screen.
Choose “About This Mac.”
Click Storage.
Note: If you are running an older version of OS X you may have to first click “More Info…” and then “Storage”.

Take a look at my hard drive disk:

I’ve got 500GB of storage, and about 275GB of it is free.

So, how big is your hard disk? Hp dts studio sound battery. How much free space do you have (if any — *gulp*)? And what’s taking up the most space? It is important to consider drive capacity and data storage needs for future storage plans — we’re not just here to fix the problem, for now, we’re going to make sure you never have this problem in the future as well.

Now that we have the knowledge, it’s time to take action and fix your Mac’s “Startup Disk Full” problem.

How to clear disk space on Mac

Let’s go over 11 things you can do to help fix 'your disk is almost full.' These should also give you other ideas as to how else to fix it — You know your Mac better than we do!

1. Clear system storage on Mac

System storage cleanup sounds like a serious undertaking. But, technically, it boils down to just one thing: having the courage to scrap the old files.

Search for large ZIP/RAR archives in Downloads.
Open your Desktop (Command + F3) and delete screenshots.
In Applications, sort your apps by size. Delete the largest ones.
Restart your Mac to free up RAM.
Get rid of system junk files with a free version of CleanMyMac X.

This app gives you lots of possibilities to free up space, especially when it comes to system junk. CleanMyMac X has been notarized by Apple, which basically means it's safe to use. And if you got 5 minutes, try this tool as it shows you where exactly your junk hides.

2. Clean up cache files on your Mac

Cache files are files that help your Mac run programs a bit more smoothly. Think of them like blueprints for a house: your Mac has the blueprints for how a program is supposed to load/run/look, so it loads it faster; without them, it’d be like building it from scratch. However, over time, these caches can start to take up some serious space. Periodically, removing them can help clear storage. And don’t worry, your Mac will create fresh, new ones after you restart your Mac. To remove caches:

Open a Finder window and select Go in the menu bar.
Click on “Go to Folder…”
Type in ~/Library/Caches
Delete the files/folders that are taking up the most space.
Now click on “Go to Folder…”
Type in /Library/Caches (simply lose the ~ symbol)
And, again, delete the folders that take up the most space.

Deleting cache files is generally safe for your Mac. And once you delete them, the applications and processes you run on your Mac will generate fresh, new ones. But, when deleting, worry more about removing them based on size rather than just removing all of them.

Also, you can check the /System/Library/Caches folder as well, but it might be better not to touch this folder without knowing what the items are. A utility that correctly cleans up these files (and pretty much everything else on this list) is, you guessed it, CleanMyMac X. It cleans up even your system caches with just a few clicks.

Oh, and once you’re done with this list, restart your Mac so it can create these new cache files.

3. Get rid of localization files

Localization files are also known as “language packs.” Lots of apps come with other languages that you probably don’t need. To clear up space on your Mac, delete the ones you don’t need:

Open a Finder window.
Go to Applications.
Ctrl+click on an application.
Select “Show Package Contents.”

From here, go to Contents > Resources and look for files ending in .lproj. These are the languages your app has just in case you want to use it in another language, like Spanish (es.lproj). Drag the ones you’ll never use to the Trash.

Again, a safer alternative to this would be to use CleanMyMac X. It gets rid of all of them with a click. No digging through application folders, just a cleaner Mac.

4. Delete duplicate files

Even if you have the most organized Mac on a planet, duplicates happen one way or another. It can be a file you’ve mistakenly downloaded twice or a mail attachment you’ve opened several times. Regardless of how they appeared, those files sit on your Mac and gobble up storage.

But finding and deleting them is a time-consuming process if you do it one by one. So here’s what you can do for a simple Mac disk cleanup:

Open the Finder app on your Mac
Move cursor over File and click New Smart Folder
Click the “+” button in the upper right corner and choose the type of files you want to see
Now sort them by name to quickly spot duplicates.

Remember to pay attention to the date of creation to make sure you keep the true original, not the copy.

While this is the best way to remove duplicates manually, it takes lots of your time and dedication. It’d be much easier to leave this to Gemini 2: The Duplicate Finder.

This app quickly scans your Mac for duplicate and similar files and allows you to delete them within minutes. It keeps your originals safe and helps you easily retrieve files deleted by accident.

5. Remove old iOS backups

Backups can tend to take up a lot of space. You can find and remove them by:

Launching a Finder window.
Clicking “Go” in the menu bar.
Selecting “Go to Folder…”
Then, type in ~/Library/Application Support/MobileSync/Backup/

Get rid of all the old, outdated backups your Mac has been storing for a bit more extra space.

6. Remove large and old files

Keeping many large files on your Desktop and in Documents slows down the system. And if you delete only a couple of these enormously large files, you can get half of your storage back.

Let’s open the familiar About this Mac pane once again. If you click Manage, you’ll see this window for sorting files.

While this instrument is good for finding large files, it misses a lot of things. See that “Other” category that takes up 38.GB?

Acrobat reader pro 9. To deepen your search for massive files, use this tool from CleanMyMac X. It’s called Large & Old files finder.

It’s much more helpful as it shows you lots of other categories of files, like Archives. The app breaks your files by Size and Last Used.
To see this instrument in action, download the free edition of CleanMyMac X. And click the Large & Old files at the bottom of the sidebar.

7. Remove unnecessary applications

This isn’t often overlooked, but definitely under-appreciated. Removing old, unused applications is a great way to get some extra space on your startup disk. Go through your applications folder and get rid of all the apps you rarely use. But make sure you remove them correctly, don’t just drag them to the Trash. If you do, you’ll leave behind tons of leftover parts and pieces, and we’re trying to get back startup disk space — It’ll kinda defeat the purpose, no?

This is another place we’d suggest using CleanMyMac X. To completely remove any application, just launch CleanMyMac X, click Uninstaller, select your application, and then click Uninstall. You won’t have to search all over for development junk that’s left behind when Trash’ing an application. It’s incredibly easy and saves you tons of time.

8. Move your Photos and Docs to the cloud

When your local storage is full to the brim, your Mac will start uploading this data to iCloud. But only if you have this setting enabled. Is your Photos app synced with iCloud already? Let’s check.

Open Applications and find the Photos icon.
Launch Photos and click on Preferences in the top menu.

Ticking the box iCloud Photos will connect your Photos library to iCloud. And what’s more important, if you select Optimise Storage, some part of your Photo library will be moved to iCloud. This way you macOS saves precious space. The free iCloud plan allows you to free up at least 5 GB worth of storage.

The similar logic applies to your Documents and other files. To set up the cloud backup with iCloud drive, go to System Preferences > Apple ID > iCloud.

9. Clean up your Downloads, Movies, and Music folders

Have a closer look at these three folders. You’d be surprised at how many downloads can accumulate when you aren’t paying attention. Clean out anything you don’t need (or don’t know) and organize the rest. It’ll take a load off your mind to know that there’s nothing excess there.

The Movies folder can be a pain, not because you’re searching through tons of files, but it can be difficult to choose what to delete. Personally, I never want to get rid of Top Gun. It’s amazing. I watched it 3 times in a row last weekend. But alas, sometimes you need to make sacrifices for the health of your Mac. Though, what you can do with movies you want to keep is to archive them. So, archive what you wish to keep and remove the rest.

How to archive/compress a file

Archiving a file doesn’t mean to store deeper into the abyss of your Mac — but to turn the file into something smaller, into a compressed file (like .zip or .tar). By archiving a file, you shave off some memory. Archiving is essential for things you want to keep on your Mac, but don’t often use, and helps you clear up some space. And that’s what this is all about right? We’re essentially doing the hokey-pokey on your Mac. To archive a file, just:

Ctrl+click the file you want to compress (recommended for movie files).
Select, “Compress .”

The last place to sweep through is the Music folder. Find and remove duplicate music files first, and then clean up all the songs you downloaded on a weird Sunday afternoon cleaning the house.

10. Clean your Desktop

“Clean my desktop… but why?” Because some people’s desktops are hard to look at, that’s why. Organize your desktop and get rid of the stuff you just don’t need on there. It looks better and helps your Mac act a bit faster (I don’t know the rocket science behind this one, but it feels too good to be false). Your Mac doesn’t waste time loading all those icons and junk, just… Just clean it, please.

11. Empty out the Trash (No, we’re not joking…)

Seriously: It may sound incredibly basic, but it could clear a surprising amount of storage. I forget to do it all the time. The thing is, that when you delete something, your Mac doesn’t remove it — it just moves it to the Trash. Plus, you’ve probably deleted way more than you realize, and all that could be sitting in the Trash, wasting space. So get rid of all that junk by emptying the Trash:

Ctrl+click your Trash in the Dock.
Select “Empty Trash.”
And click “Empty Trash.”

And, the easiest step is done.
