Nov 04, 2013 I'm a long-time Mac user with a 2010 MacBook Pro (320GB) now running Mavericks. About a week ago I screwed up my iTunes and tried to restore from Time Machine. But I can't because I only have 38GB free and the TM backup is about 40. So I moved big files over to my attached drive to free up space. How to Free Up Space on Google Drive on PC or Mac.

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.
Click the Manage button to open the Storage Management window, pictured below.
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.
Optimise Storage
Click the Optimise button to save space by automatically removing films and TV programmes you've watched. When storage space is needed, films or TV programmes that you've purchased from Apple and have already watched will be removed from your Mac. Click the download icon next to a film or TV programme to download it again.
Your Mac will also save space by only keeping 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.
Optimising storage for films, TV programmes and email attachments doesn't require iCloud storage space.
Empty Bin Automatically
Empty Bin Automatically permanently deletes files that have been in the Bin for more than 30 days.
Reduce Clutter
Reduce Clutter helps you identify large files and files you may no longer need. Click the Review Files button and then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation or Bin.
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.

- 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.

Most of us are keen to update to a new version of macOS as soon as it is available. macOS Big Sur has been out since November 12, still, many users couldn't update their Macs straight away. It’s very frustrating if you see a message telling you that you don’t have enough space to install the new macOS. Don’t worry, though. There are lots of things you can do to fix it. We’ll show you what they are in this article.
How much space do you need for Big Sur?
How To Get More Free Space On Mac
While the installer for Big Sur takes up less than 16GB of space, you should make sure that you have at least 20GB of free space on your startup disk before you try to download and install it. The more free space, the better. Your Mac uses disk space to store temporary files and provide storage for active apps and tasks (which is what RAM does), so you should never be running with almost no disk space left.
CleanMyMac X makes it very easy to free up disk space on your Mac by identifying junk files and allowing you to get rid of them with a click. It can also detect large and old files and show you the files taking up most space and uninstall applications.
How to free up space for macOS Big Sur?
Complete the following steps to ensure your Mac is ready to update to Big Sur.
1. Backup your Mac
Back up all files and data that are stored on your Mac. Preferably twice to different locations. While upgrading to Big Sur is safe, you never know when something might go wrong. If you use Time Machine or another backup tool, run a manual backup just before you upgrade. And, if you can, clone your startup disk to an external drive, too.
2. Free up disk space using CleanMyMac X
If you don’t already have CleanMyMac X installed, download it for free here. This tool will help you clear some space and delete large and old files quickly.
- Launch CleanMyMac X.
- Choose System Junk in the sidebar and press Scan.
- When it’s finished, press Clean to free up space, or Review Details to find out more.
3. Get rid of large and old files
Media files usually gobble up a large amount of disk space. And the worst thing is they are scattered around Mac’s folders, making it difficult to find and remove them. CleanMyMac X proves to be useful here:
- Choose Large & Old files in CleanMyMac X’s sidebar.
- Press Scan.
- When it’s finished, use the middle column to filter files by type.
- Check files that you want to delete.
- Press Remove.
4. Use Apple’s built-in storage management tool
Apple has provided a method for you to manage storage by showing you what is taking up disk space and making recommendations for deleting. It’s not as quick and easy as CleanMyMac X, but it can help you save disk space. Here’s how to use it.
- Click on the Apple menu and choose About this Mac.
- Select Storage and press Manage.
- In the Recommendations section, review each section in turn.
- Now go through each of the sections in the sidebar.
- Delete files or take further action, depending on what you choose.
5. Delete local Time Machine snapshots
There is one other thing you can try if you keep getting a message telling you that you do not have enough space to install Big Sur. You should only try it if you are sure there is enough space on your startup disk and that the message is wrong. And it will only work if you use Time Machine to back up your Mac.
Time Machine stores local snapshots on your Mac. Your Mac is supposed to count the space used by snapshots as free space, which is why it looks like you have enough space for the installation.
However, it seems that the installer may not realize the space is free. The solution is to delete the snapshots. This won’t remove backups on your backup disk, just snapshots on your Mac.
Open Time Machine from System Preferences. Uncheck Back Up Automatically and wait some time till Time Machine deletes snapshots. Then you can turn Time Machine back on.
If you’re familiar with Terminal, you can try deleting local snapshots manually.
- Go to Applications > Utilities and launch Terminal.
- Type:
tmutil listlocalsnapshots /
- You will see a list of snapshots that look like this:
com.apple.TimeMachine.2020-10–09-002010.local
- To delete a snapshot, type:
sudo tmutil deletelocalsnapshots
- Then type the date part of the snapshot name. For example:
sudo tmutil deletelocalsnapshots 2020-10–09-002010
- Type Return and repeat for each snapshot you want to delete.
Hopefully, this helped you free up some space and update your Mac to the latest OS. If you're just preparing your Mac for the upgrade, don't forget to back up your data before you start clearing space. So you won't be afraid of losing anything important.
