When less than 20 percent of the space on your Mac’s startup disk is available — or if less than 5 GB of space is available — your Mac will start automatically purging the oldest Time Machine local snapshots to free up space. At less than 10 percent or 5 GB available, your Mac will become even more aggressive. Ways to free up disk space on a Mac. Before we show you how to clear disk space on your Mac, a word of caution is in order. Hard drive cleaning requires time and, in some cases, expertise. So, when in doubt, use a professional cleaning app. Now, let’s make some room for the files that truly deserve space on your Mac. If you use iOS devices, try to back up your devices with iCloud. Your mac may end up with multiple backups when you use iTunes for back up. Deleting such old backups will free up some space. Remove Unused Applications. Removing outdated, unused applications is actually a wonderful means to free up disk space. The limitations of Mac storage often create a problem that prevents the Mac from running smoothly, which results in inconvenience to every user. With that said, we take a look at the four ways to free up the storage space on the device manually, according to Apple. How to Free Up Storage Space Manually on Your Mac 1.
A slow Mac is no fun for anyone. It happens to the best of us — which is why everyone should know how to declutter and free up disk space on their Mac. Not only will this speed up your computer, it’s also a great opportunity to organize your files.
Clearing disk space on a Mac can make your computer feel like new. Over time, most Macs, especially those that experience regular use, get full of documents, files, apps, images, videos, and other junk and clutter.
In this article, we’ll show you how to free up space on Mac computers, and highlight some apps that make maintenance of your computer’s file system much simpler.
What's taking up space
Have you ever seen this pop up on your Mac?
It’s frustrating! This occurs because the memory your Mac has is full. It may be saved movies, large documents, mail attachments, or just plain cached items from apps like iMessage that are taking up space on your Mac.
Not only is the popup message annoying, diminished disk space on your Mac can prevent you from being productive. Mail attachments or other files may not save to your Mac, all because you’ve got a bunch of old stuff cluttering your memory system. It can even cause apps to quit, or fail to load.
Low disk space isn’t always an 'old Mac' problem, either. While it’s true older Macs typically have less memory available to them, even modern Macs can get cluttered. That’s why it’s important to know how to clear space on Mac hard drives.
How to check storage on Mac
Here’s how to check the storage on your Mac using Apple’s method:
- From the menu bar on your Mac, click the Apple logo on the top left
- Select 'About this Mac'
- Select the 'Storage' option in the new window
This is a basic way to check how much storage is being occupied on your Mac. Another good tip is to check your disk usage with iStat Menus. It’s an app that allows you to monitor – in real time – how your Mac is performing. iStat Menus lives in your Mac’s menu bar, running in the background until you need it. Each of its monitoring services has a menu bar icon, including one for memory.
When you click on the iStat Menus icon, it shows you exactly what’s happening with your disk space. When your Mac is running slowly, it’s possible an app is taking up more resources than you would like. iStat Menus shows you which app is to blame.
How to optimize storage using macOS
If you’re using macOS Sierra or later, you can benefit from Apple’s Optimize Storage functionality. It allows you to store files in iCloud, renewing your access to these files whenever you need. Here’s how to use the Apple way of managing storage on Mac:
- Repeat the steps above to check the available and used storage on your Mac
- Click on 'Manage' to access the storage management window
- Enable the 'Empty Trash Automatically' and 'Reduce Clutter' options to remove files you deleted, and large files you might no longer need.
- Select 'Store in iCloud' to move your desktop file and docs, photos, and messages to iCloud. You can choose what file types to transfer.
Go to the Optimize Storage menu and choose from three options that help you use storage more cleverly. You can select to remove watched files from your Apple TV app (or iTunes if you use macOS Mojave and earlier), download only recent attachments, or not to delete attachments at all. Also, read an article about how to clear scratch disk.
Move Files to the Cloud
iCloud is Apple’s preferred method for storing files and folders in the cloud. It makes your data available across devices, and is now the default service for system backups.
Apple gives you 5GB free iCloud storage, but it’s just enough for an iPhone backup and a few gigabytes of pictures. It’s almost never enough for the average user.
Activating it on your Mac will help save room in your system memory, though. It moves the actual storage of files to the cloud, and ann image of those files on your Mac. It also compresses images for optimized storage on the Mac, but keeps them available in the Photos app.
If you have a different cloud storage system you prefer, CloudMounter makes it easy to back your Mac’s files up to Google Drive, Dropbox, OneDrive, Mega, Amazon S3, and other services. It lives in your Mac’s Finder app and menu bar, and makes moving files from your Mac to the cloud as easy as dragging and dropping them into CloudMounter, and directly into your connected cloud account.
Manage large files and archive data
You can find and delete large files on your Mac directly. Here’s how:
- From the menu bar on your Mac, click the Apple logo on the top left
- Select 'About this Mac'
- Select the 'Storage' option in the new window
- Select 'Manage'
- Select 'Documents'
- On the right side of the window, click the 'Size' column header to show the largest files first
We prefer using CleanMyMac X’s file system manager. Here’s how to use it:
- Open CleanMyMac X on your Mac
- Select the 'Large & Old Files' module on the right side of the window
- Select 'Scan'
This is a smarter way of discerning which files are taking up space on your Mac – especially if you don’t need access to those files often. It shows you which types of files they are, how old they are, and lets you delete batches of files by size.
Find and delete duplicate files
When you download an app, it usually has associated files it stores on your Mac. That’s normal; duplicates of those files aren’t. Downloading an app more than once, or even updating an app, can cause it to duplicate existing files on your Mac.
You may also download files more than once. Your Mac is smart, but doesn’t bother checking to see if you already have a file before downloading it again. There’s no clean way to check for duplicates on your Mac. Apple would ask that you look for duplicated filenames in your storage, and delete one of them.
A better way is to use Gemini, an innovative cleanup app built to help you find and eliminate duplicate files on your hard drive. Even better, it can identify near-identical files as well, giving you an easy way to delete the slightly shaky versions of your vacation snaps in one convenient window.
Here’s how to detect and delete duplicate files with Gemini:
- Open Gemini on your Mac
- Click the ‘plus’ icon, or drag a folder to the app
- Select 'Review Results' to delete files manually, or 'Smart Cleanup' to allow Gemini to delete all duplicates
Remove temporary files
Your macOS, your apps, and your browser all use a shortcut called 'caching' to run faster. But over time, those caches fill up with useless information that bogs down your computer.
Why is it important to clear the cache? The short answer is that caches litter and bloat Macs. They aren't just a byproduct of browser history — most systems and apps, such as Pages, Numbers, Keynote, Mail and Photos, create huge amounts of temporary files that linger in the background. These caches of data are essentially just junk files, and they can be safely deleted to free up storage space.
When it comes to cleaning a Mac, you have two options: delete files manually or get a cleaner app to help you. Clearing your cache files with CleanMyMac is the quickest, safest way we know.
Get rid of hidden trash
Another source of system-slowing junk is email and text attachments. Even if you don’t download an attachment, your desktop mail client holds onto a version so that it can show you previews and access the file more easily. 'But I deleted that email!' you say. Often that’s not enough—these downloads can hang around long after the original email is gone.
It’s possible to clean them out manually. You can use the macOS Optimize Storage feature we’ve described above. Choose what exactly you want to be removed — mail attachments, watched video, or both. Still, CleanMyMac X is a much faster option to clean up the trash on Mac. Here’s how to use CleanMyMac X to empty all trash folders on your Mac:
- Open CleanMyMac X on your Mac
- Select 'Trash Bins' from the left hand side
- Select 'Scan' at the bottom of the window
- Select 'Review Details' to see what CleanMyMac X found, or 'Empty' to delete all trash files on your Mac
Here’s a little trick for you: If you want to be sure you keep the needed files and attachments at your fingertips, use Trickster app to remember them for you. Configure your file tracking inside the app and make sure you’re never confused about what’s stored on your Mac. The important stuff is always in Trickster.
If you want a clutter-free email client, Canary Mail is your perfect choice. The app not only automatically clear away the trash, but also allows to automatically unsubscribe from tons of mailing lists — so that you stop receiving the clutter.
Empty downloads and trash bin
Your Mac’s ‘download’ folder is where most apps, like Safari or Chrome, dump files. It’s also the default folder for email downloads. And it can get really full.
Many of us simply download a file, access it, then forget about it once we’re done with it. The downloads folder can get chock full of files we no longer need, or want. It’s smart to comb through it ever so often and delete files you don’t want, or move them to cloud storage containers using CloudMounter.
Some downloads are hidden, taking up even more space. And the further back you go the more useless these documents are. Do you really need to keep a text file labelled 'Christmas shopping list 2015' or 'Dream holiday Summer 2016?' Probably not. Free up some much-needed space on your Mac and delete as many of these old download files as possible, and remember to come back and tidy it up every few months.
CleanMyMac can help for sure. But also, consider switching your email client to Unibox, which automatically reduces excessive downloads.
AppleInsider described Unibox as 'the best client we tried,' and Macworld said it is 'A welcome, fresh new approach to email on the Mac.' Unibox groups emails by sender and includes an attachment list, so you can quickly find what you need, then delete those documents out of the Downloads folder.
Uninstall unused apps
Have you ever downloaded an app, then stopped using it? We all have! Those apps occupy memory on your Mac – sometimes a lot of space, too.
CleanMyMac X has a handy 'Uninstaller' module which makes it easy to identify and remove all unwanted apps from your Mac. It even deletes associated files, so all traces of an unused app are taken away.
Get rid of old backups
Something else that comes as a surprise to most Mac users is just how many backups your system carries at any given time. Copying and pasting, and the duplicate feature make it too easy to replicate your work in different folders.
At the same time, you’ve probably got dozens of cached backups of files and documents that are invisible but taking up more space than you’d want. Like Time Machine backups. Every time you use Apple’s built-in backup utility, it creates local snapshots that are stored locally on your Mac. This may result in up to 100 GB Time Machine clutter on your hard drive.
CleanMyMac will find old backups for you and remove them in a click. In its 'Maintenance' module, you can select 'Time Machine Snapshot Thinning' to automatically remove older Time Machine backups you no longer need.
But also, switch your backup client to Get Backup Pro to backup only those units you want (for Mac). If you need to quickly transfer files or folders to another server, use a backup sync app ChronoSync Express.
If you want to quickly backup your iOS device on Mac — for instance, before hard resetting or factory resetting iPhone — you can use AnyTrans. You can even schedule instant backups to never worry about losing data when syncing your iOS device with Mac.
Get rid of desktop clutter
Organizing your Mac desktop doesn’t directly help your memory woes, but it can help you find files faster and avoid multiple downloads of the same file.
Apple’s chosen method is called Stacks. A simple right-click on your desktop brings up a menu; selecting 'Use Stacks' puts your files into folders by type. Images, screenshots, and other files will be held in expandable folders, decluttering your desktop for good. Future downloads will all fall into those categories, too.
You may prefer Spotless, an app that affords you far more control over how your desktop is organized. You can set rules for organization, and tuck files into other folders on your Mac by dragging and dropping into one location. Spotless takes care of the hard work for you!
You deserve a faster Mac
By eliminating both hard disk and desktop clutter, you’ll improve your Mac’s performance as well as your own workflow. Plus, Setapp’s decluttering, disk cleanup, and analysis apps help you complete what would be a tedious chore in just a few clicks. There’s no telling how much time and effort you’ll save by giving yourself (and your Mac) a break.
There are plenty of great ways to manage your Mac’s memory without rushing out to buy a new computer. We’ve shown you the best ways here!
All the apps we mentioned in this article are available for free during a seven day trial of Setapp, the world’s best suite of productivity apps for the Mac. In addition to ClanMyMac X, Spotless, Gemini, CloudMounter, Get Backup Pro, and ChronoSync Express, you’ll have unlimited access to Setapp’s full catalog of nearly 200 Mac apps. When your free trial is over, Setapp is only $9.99 per month. Give it a try today!

- Example:
If you are a Mac user and you have a smaller HDD Macbook, chances are you have seen this message at least once: “Your startup disk is almost full” or you want to know how to free up space.
In this article, I will explain why this happens and how to never see this warning ever again!
How to free up space on a Mac?
What is a “Mac Startup Disk”?
Your Mac startup disk is a volume or a partition of a drive that contains a usable operating system. You can set your Mac to automatically use a specific startup volume, or you can temporarily override this choice at startup.
What this means is that the startup disk is the “home” of all the files needed for starting your Mac and using it.
How To Free Up Space On Your Mac Disc
Without a startup disk, you will not be able to switch on your computer.
Why is my Mac “Startup Disk Full”?
In short, you have too many files. When this happens, it slows down all processes on your computer – see, in order to complete some tasks, your computer needs space to store temporary files and system files. When this happens and you run low on storage, the operating system needs to decide whether it can delete some files in order to complete the task. Most of the time this is not possible and the computer crashes or becomes very, very slow.
It is recommended that a startup disk should never be at above 85% of its capacity in order to work properly.
How to see the used Storage on a Mac?
If you want to see the exact types of files that are using the storage on your Mac:
Click the Apple in the top-left corner
Click on “Storage”
Currently, I have 73.9 GB used and 425.2 GB Free.
Most of my used storage is from “Other”
What is “Other” in the Mac Storage?
According to Apple, in OS X El Capitan or earlier versions, “Other” files are those that your Mac doesn’t recognize as belonging to any other category. These include files within disk images or archives, data stored by apps such as Contacts or Calendar, and app plug-ins or extensions. When your Mac is running in Safe Mode, all files are categorized as Other.
How to Fix Mac Startup Disk Full with pCloud Drive?
What is pCloud Drive
pCloud Drive is a desktop application that creates a secure virtual drive on your computer, which you can use to easily store, access and work with your files in the cloud.
To add files and folders to your pCloud Drive, simply drag and drop* your data into your virtual drive. You can then be sure that they are safely stored in the cloud and synchronized on all of your devices.
*for this to work fast you need to have at least some free storage on your startup disk. If you don’t, keep reading!
pCloud Drive provides a number of additional functionalities, such as integrated file sharing and synchronization through your computer.
Note: If you have very low disk storage you must do the following:
Choose the folder you want to Sync with pCloud:
Click on the pCloud icon and choose Sync to pCloud:
Create a folder on pCloud Drive:
Wait for the Sync to be completed:
This is very Important! After the Sync is finished, you must stop it with the cross icon:
After you stopped the Sync you can delete the files you just synchronized:
You can go to pCloud Drive and see the files you synced and use them as if they are on your computer! (A green icon means everything is synced.)
The app significantly eases your work upon performing file operations in the cloud, because with pCloud Drive you can work with your files using any software on your computer.
What this means is that if I have a vacation video in pCloud Drive I can watch it with no problem with the default video player on my computer. In my case VLC Player.
The best thing is that since the video is in pCloud Drive it is not actually on my computer but it’s in the cloud and does not take ANY of my Startup Disk Space!
Another awesome thing is that I can watch this video also on my phone with the pCloud mobile apps OR if I’m using a different computer that does not have pCloud Drive, I can watch it via Chrome, Firefox or any other internet browser. I just need to go to my.pcloud.com and sign in. Here is what I see:
Same thing works for:
How To Free Up Space On Your Macbook
– Documents – I can open and edit them with any text editor with pCloud Drive or access them from any of the other apps. The same works for worksheets, PDFs, presentations etc.
– Photos – I can open them, see them or edit them with Photoshop or any other image editor.
– Audio files – I can listen to them on my default music player or with pCloud mobile and web apps music player. I can even create playlists within pCloud.
– Every other type of file – As long as I have an app or a program to open the file with, there is no problem for pCloud Drive.
Nice right?!
What this means is that you can move all the files that are using your Mac Startup Disk Storage in pCloud Drive.
That way they WILL NOT use any of the space on your computer and you will still have access to them and use them with the apps installed.
Example:
I have a 512GB SSD Macbook Pro Retina. I also have a pCloud Premium account which is 500GB of storage. This makes my Macbook capable of storing 1TB worth of files.
Sharing with pCloud Drive
You can share any file or folder that you have in pCloud Drive.
You just right-click on the file or folder you want to share and choose if you want to invite someone to the folder or create a so called Download link.
This way you can collaborate with people or share the vacation photos and videos with your friends for example.
pCloud Speed
When you use pCloud Drive, you don’t even understand that your files are not stored locally. That’s because of the super high speed that we offer for uploading and downloading files. We compared our upload and download speed with the ones of Dropbox and here are the results for 1.12GB file:
pCloud Security
To guarantee your files’ safety, pCloud uses TLS/SSL encryption, applied when information is transferred from your device to the pCloud servers.
Your files are stored on at least three server locations in a highly secure data storage area.
Optionally, you can subscribe for pCloud Crypto and have your most important files encrypted and password protected. We provide the so-called client-side encryption, which, unlike server-side encryption, means that no one except you will have the keys for file decryption.
Free Space On Mac
Conclusion
A lot of Mac users have the same frustrating problem. Startup Disk Storage fills up quickly on smaller versions (128GB and 256GB) and if you use it for work, you can fill up a 512GB Mac very fast too. Especially if you are a designer or a video editor for example, and work with large files. And even if you are not creating huge files, with the pace we are creating information is growing very fast:
Just think about this: smartphones and cameras that can shoot RAW files and in 4K, which means you’ll have photos and videos of amazing quality – but they will also take a lot of memory so the more space you have, the better.
pCloud Drive helps you virtually add storage to your Mac (or any PC for that matter). You can move your photos, videos, music, documents any other kinds of files there and use them as if they are on your device with the apps you are used to. Also, you can access them on a smartphone via the pCloud mobile apps for iOS, Android, and Windows 10 Mobile, and in a web browser when you go to the website and sign in.
