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.
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.
How To Free Up Space On Your Mac Disk
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:
How To Free Up Space On Your Mac
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:
– 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.
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.

The Optimised Storage features of your Mac help you save storage space by storing your content in iCloud and making it available on demand:
- When storage space is needed, files, photos, films, email attachments and other files that you rarely use are stored in iCloud automatically.
- Each file stays exactly where you last saved it, and will be downloaded when you open it.
- Files that you’ve used recently remain on your Mac, along with optimised versions of your photos.
If you haven't yet upgraded to macOS Sierra or later, find out about other ways to free up storage space.
Find out how much storage is available on your Mac
Choose Apple menu > About This Mac and 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.

Manage storage on your Mac
The Storage Management window offers recommendations for optimising your storage. If some recommendations have already been turned on, you will see fewer recommendations.
Store in iCloud
Click the Store in iCloud button and 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've opened recently will be kept on your Mac, so you can work offline easily. Files stored only in iCloud display 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 (optimised) 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. Find out 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 50 GB for US$0.99 a month, and you can purchase additional storage directly from your Apple device. Find out more about the prices in your region.

- 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 may display storage categories, such as Not Mounted, VM, Recovery, Other Volumes, Other, 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 won't use additional storage space on the volume. Deleting a duplicate file only frees up the space required by any data that 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.
