Spaces was a virtual desktop feature of Mac OS X, introduced in Mac OS X 10.5 Leopard. It was announced by Steve Jobs during the opening keynote at the Worldwide Developers Conference on August 7, 2006. As of Mac OS X 10.7 Lion, it has been incorporated into Mission Control. Simply in a form of general Mac system hygiene. That’s about all you need to know about what is purgeable space on Mac, so we hope this article has been of help. MacOS is a great addition to Mac, we’re glad it has space-saving features and other cool stuff (Siri!) but it could’ve been a bit clearer to users, that’s for sure.
Optimized Storage helps you save storage space space by storing your content in iCloud and making it available on demand:
- When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically.
- Each file stays right where you last saved it, and downloads when you open it.
- Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.
If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.
Find out how much storage is available on your Mac
Choose Apple menu > About This Mac, then click Storage. Each segment of the bar is an estimate of the storage space used by a category of files. Move your pointer over each segment for more detail.
Click the Manage button to open the Storage Management window, pictured below.
Manage storage on your Mac
The Storage Management window offers recommendations for optimizing your storage. If some recommendations are already turned on, you will see fewer recommendations.
Store in iCloud
Click the Store in iCloud button, then choose from these options:
- Desktop and Documents. Store all files from these two locations in iCloud Drive. When storage space is needed, only the files you recently opened are kept on your Mac, so that you can easily work offline. Files stored only in iCloud show a download icon , which you can double-click to download the original file. Learn more about this feature.
- Photos. Store all original, full-resolution photos and videos in iCloud Photos. When storage space is needed, only space-saving (optimized) versions of photos are kept on your Mac. To download the original photo or video, just open it.
- Messages. Store all messages and attachments in iCloud. When storage space is needed, only the messages and attachments you recently opened are kept on your Mac. Learn more about Messages in iCloud.
Storing files in iCloud uses the storage space in your iCloud storage plan. If you reach or exceed your iCloud storage limit, you can either buy more iCloud storage or make more iCloud storage available. iCloud storage starts at 50GB for $0.99 (USD) a month, and you can purchase additional storage directly from your Apple device. Learn more about prices in your region.
Optimize Storage
Click the Optimize button to save space by automatically removing watched movies and TV shows. When storage space is needed, movies or TV shows that you purchased from Apple and already watched are removed from your Mac. Click the download icon next to a movie or TV show to download it again.
Your Mac will also save space by keeping only recent email attachments on this Mac when storage space is needed. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.
Empty Trash Automatically
Empty Trash Automatically permanently deletes files that have been in the Trash for more than 30 days.
Reduce Clutter
Reduce Clutter helps you identify large files and files you might no longer need. Click the Review Files button, then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation, or Trash.
You can delete the files in some categories directly from this window. Other categories show the total storage space used by the files in each app. You can then open the app and decide whether to delete files from within it.

Where to find the settings for each feature
The button for each recommendation in the Storage Management window affects one or more settings in other apps. You can also control those settings directly within each app.
- If you're using macOS Catalina or later, choose Apple menu > System Preferences, click Apple ID, then select iCloud in the sidebar: Store in iCloud turns on the Optimize Mac Storage setting on the right. To turn off iCloud Drive entirely, deselect iCloud Drive.
- If you're using macOS Mojave or earlier, choose Apple menu > System Preferences, click iCloud, then click Options next to iCloud Drive. Store in iCloud turns on the Desktop & Documents Folders and Optimize Mac Storage settings.
- In Photos, choose Photos > Preferences, then click iCloud. Store in iCloud selects iCloud Photos and Optimize Mac Storage.
- In Messages, choose Messages > Preferences, then click iMessage. Store in iCloud selects Enable Messages in iCloud.
- If you're using macOS Catalina or later, open the Apple TV app, choose TV > Preferences from the menu bar, then click Files. Optimize Storage selects “Automatically delete watched movies and TV shows.”
- In you're using macOS Mojave or earlier, open iTunes, choose iTunes > Preferences from the menu bar, then click Advanced. Optimize Storage selects “Automatically delete watched movies and TV shows.”
- In Mail, choose Mail > Preferences from the menu bar, then click Accounts. In the Account Information section on the right, Optimize Storage sets the Download Attachments menu to either Recent or None.
Empty Trash Automatically: From the Finder, choose Finder > Preferences, then click Advanced. Empty Trash Automatically selects “Remove items from the Trash after 30 days.”
Other ways that macOS helps automatically save space
With macOS Sierra or later, your Mac automatically takes these additional steps to save storage space:
- Detects duplicate downloads in Safari, keeping only the most recent version of the download
- Reminds you to delete used app installers
- Removes old fonts, languages, and dictionaries that aren't being used
- Clears caches, logs, and other unnecessary data when storage space is needed
How to free up storage space manually
Even without using the Optimized Storage features described in this article, you can take other steps to make more storage space available:
- Music, movies, and other media can use a lot of storage space. Learn how to delete music, movies, and TV shows from your device.
- Delete other files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
- Move files to an external storage device.
- Compress files.
- Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.

- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
- If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
What is taking up space on my Mac?
There comes a time in every computer's life when it is full of files and programs, slowing it down so much that its owner searches for an article such as this in order to cure it of these ailments (before it gets thrown out the window!).
Worry not, you're in the right place. This article will take you through 8 steps which will free up space on your Mac - removing unneeded files and clearing space for the stuff you actually need.
No matter if you're tech savvy or not, anyone can use these tips to breathe new life into their Mac.
To find out how much space is available on your Mac:
- Open the Apple menu (the Apple icon in the top-left corner of your screen).
- Click 'About this Mac'.
- Click 'Storage'.
This overview will show what categories are taking up the most space, as well as how much space is available on your Mac.
The 8 sections below address the biggest culprits of space-hogging on your Mac and how to clean them up.
Jump straight to:
1. Mac OS Storage Management
The first port of call when making space on your Mac is to see what tools your Mac offers you for such a task.
If your Mac is running macOS Sierra or later, it has great built-in tools for managing files and optimizing storage. To access these tools, click the apple icon in the top-left corner of your screen > About this Mac > Storage > Manage…
As you can see this is also how to check storage on Mac. The tool shows a breakdown of the storage space taken up on your Mac by media such as Apps, Books, Photos and others.
Let's have a look at each tool to see how it can help:
- Store in iCloud: Quickly store files (Documents, Photos and Messages) from your Mac in iCloud. When considering how to clear space on Mac, getting rid of files quickly springs to mind- However, if you need to keep the files, you can just move them to an external hard drive, or into iCloud!
Enabling this option will allow your Mac to automatically save space when it’s needed.
This is great as you’ll be able to access your files on any device using your Apple ID. However, if you have a large number of files, you’ll need to purchase more storage space than your allotted free amount (5GB)- obviously, depending on the amount of space you need, this can quickly become an expensive option.
- Optimize Storage: For those who download and watch lots of movies and TV, this option can save you a lot of space and a lot of time. Enabling this option will allow your Mac to automatically remove such files (which can be HUGE depending on their length and quality) once you have watched them.
Empty Trash Automatically: Similar to the above, enabling this option allows the automatic removal of files, saving you time and space without having to keep on top of it manually. This will remove items in your Trash after 30 days of them being there. Be aware that once files have been removed from your Trash, you will not be able to retrieve them.
Side note: Many points in this article will advise the removal of unwanted files from your Mac. However, these files are not completely removed from your computer until you empty the Trash (the space is not regained until they are removed from Trash). You can manually empty it by clicking the Trash Can icon in your dock, then clicking 'Empty'.
Reduce Clutter: Find large and unused files on your Mac and delete them from your system. You’ll need to delete them manually, but it’s well worth it if you can remove files that you do not use.
Navigate to files that you don't need using the 'Large Files' or 'Downloads' sorters, then hit 'Delete...'. Note that this action will bypass sending the item to Trash, so it's permanent.
If you're finding unwanted files using the 'File Browser' tab, you'll need to right-click > 'Move To Trash'.
2. Find Duplicate Files Mac
The quickest way to free up space on your Mac is to automatically remove files that you don’t need. Without realizing it, you can accumulate gigabytes worth of duplicate files and folders on your computer.
The problem is that it can take so much time to find and delete these duplicates that people do not bother to do it even if they want to.
Luckily, you can use an app like Duplicate Sweeper to do this for you.
Duplicate Sweeper: Easily scan your Mac for duplicate files and photos. You can then select and remove duplicates based on your preferences. In this way you can keep your newest version of files and remove all duplicates with a click of a button.
In the example below, I was able to remove over 6000 files with one-click. This freed up 2.3 GB of space on my MacBook. Imagine manually going through and comparing 6000 files without Duplicate Sweeper... it would have taken forever!

3. Unused Apps- Uninstall Programs on Mac
One of the biggest areas you should consider when looking at how to free up space on Mac is your Apps. Maybe unsurprisingly, apps on your Mac can be some of the largest files on your computer. Removing apps that you don’t use can free up a huge amount of space. Let’s list your apps by their files size:
Open Finder, then open the Applications section. Display the items as a list (using the button with 4 horizontal lines), then click the ‘Size’ header to reorder your applications by size. You can then work down the list and decide which applications you don’t use. Simply drag an application from the list into the Trash Can on your Dock to remove them.
Remember that you’ll need to empty your Trash Can to completely remove the applications from your Mac.
4. Clean up media and downloads
The quality of media like photo and video is constantly improving. Unfortunately, this usually means that the corresponding files are bigger than they used to be.
For this reason, your saved media could be a great place to free up some of that precious storage on your Mac.
Open Finder and look through your Pictures, Movies and Music folders. If there is media there that you don't want, select it and move it to Trash to get rid of later. If you prefer to delete this media from the associated apps like Photos and iMovie, see how to empty their trash.
It is also recommended to check your Downloads file for unwanted files too.
This folder can receive copious amounts of files downloaded from multiple sources. Many of these files you may have only needed to read or use once.
You can get to your Downloads folder by opening a Finder window and clicking the 'Downloads' header.
Again, select whatever files you don't need, then right-click > Move to Trash/Bin.
Extra: Zipped / Archived files
If you receive a zipped file (with the .zip extension), opening it will unzip the file or folder and create the files in a non-zipped form.
This will create files that you can use, but it will not remove the (now unneeded) zip file. If you've already unzipped, you can delete the .zip file.
On the flip side, you can use file archiving to compress files or folders that you don't use regularly.
Say you have a folder of documents that you only need to save for safekeeping; right-click the folder in Finder and click 'Compress [file/folder name]'. This will compress the files and create a .zip file.
Don't forget to delete the original, uncompressed folder in order to save the space!
5. Delete iTunes backups
Depending on the number of files, photos, messages etc that you have stored on your iPhone, iPod or iPad, it’s backup on your Mac can be huge.
Keeping backups of your devices is a good idea. If something was to happen to your device, your data can be restored to it (or another device) using your backup. However, these backup files can be massive, and you may never need them! For this reason, consider backing up your devices to iCloud instead – freeing up space on your Mac.
To set your device to backup to iCloud, go to Settings > (your name) > iCloud > iCloud Backup.
To initiate a backup, connect your device to a power source and also to a Wi-Fi network. Lastly, ensure that your device screen is locked and that you have enough free space in iCloud to store the backup.
How to delete backups on Mac - You can also delete the backups which you already have stored on your Mac. To do this, open iTunes and go to iTunes > Preferences > Devices. If you don’t need the backups in the list, select and delete them!
Find out: where are iTunes backups stored?
Alternatively, if you don’t want to use iCloud for backing up your data, or if you only need certain data from your backups, you could use iBackup Extractor. This handy tool allows you to access and browse your backups, and extract any important photos, messages etc. that you need. You can save this data to your computer, then delete the backup from iTunes as seen above!
6. How to Delete Temporary Files on Mac
Some of the most common questions asked are 'how to clear cache on mac' and 'how to delete cookies on mac'. Well, let's answer those for you!
Temporary and cache are files that are stored locally in order to speed up processes. For example, images from a website that you visited can be cached, so that when you visit the page again, you don’t have to wait to download the images again, they are simply pulled in from the cache. That’s great for processes that you use regularly, but without care, your temporary and cached files can build up and eat away at your Mac’s performance.
Let’s see how to clear cache on mac – Open Finder > Go > hold ‘option’ and click ‘Library’ > Caches. Select and delete any cache files and folders that you don’t need to save space!
7. Taking out the Trash
Deleting files on your Mac usually only moves them to your Trash Can (or Bin).
This is great, because if you 'delete' something by accident, you can restore it to its original location - no harm done.
However, if you are culling files on your Mac to make space, you may wonder why you are not gaining storage after clicking delete.
To permanently delete files from the Mac, you'll need to empty your Trash Can. To do this, simply click the Trash Can (or Bin) icon in your Dock.
Here, you can review or restore files in your Trash/Bin.
To permanently delete all the files in your bin, click Empty. You'll be asked if you're sure, and to confirm the permanent deletion of the files.
Deleting files from Photos, iMovie and Mail apps...
Generally, you'll be able to use the steps above to permanently delete files. However, some apps have their own way to manage 'deleted' files.
As such, you'll need to empty trash cans in individual apps to ensure that files are fully deleted.
An example of this can be seen in the Photos app:
Click the 'Recently Deleted' header to access the trash in the Photos app.
After 'deleting' photos from the app, the files can remain in this section for up to 40 days before being automatically deleted.
If you are sure you'd like to permanently delete these photos, click 'Delete All' to remove them from your hard drive.
You can use similar steps to empty trash for other apps like iMovie and Mail.
8. Move files into external storage
Free Up Space Mac Os
The majority of the methods above cover how to delete unwanted files to gain space. But what you if want to keep your files?
If you need more space on your Mac, but deleting your files is not an option, you may want to consider investing in external storage.
You can purchase external storage drives pretty cheap nowadays.
Disable Spaces Mac
The way this works is that you connect your external drive with your Mac via USB cable. The drive then pops up as a Location on your Mac:
You can then drag files from your Mac onto your external drive, or cut/paste them into specific folders on your drive.
