Don’t Have Enough Space to Update Mac? Here’s What You Need to Do

How Much Space macOS Updates Need

Before starting the update, it is important to know how much space is required. macOS updates can take anywhere from 10 GB to 25 GB, depending on your version and model. This includes both the installer size and the temporary files needed during installation. It’s best to keep at least 30 GB of free space for a smooth update process. If you are short on storage, don't worry; there are quick and safe ways to free up space.

Ways to Free Up Space Quickly

When you see the alert saying what to do if there is not enough space to update Mac, it simply means your system does not have sufficient storage to download and unpack the update files. You can quickly fix this by identifying what’s taking up space and removing unnecessary data. Here are some simple ways to do that:

• Empty the Trash to remove deleted files permanently.

   

• Remove old downloads and unused large documents.

   

• Clear cache files and temporary data.

   

• Move photos and videos to external drives or cloud storage.

   

• Uninstall apps you no longer use.

   

These actions can easily give you several gigabytes of free space, enough to continue your update without issues.

Clear Cache and Junk Files

One of the quickest methods to free up space to update your Mac is by clearing cache and junk files. Over time, your system stores temporary data, app logs, and unnecessary files that can fill up your disk space. Follow these steps to clear them:

• Open Finder and click Go in the top menu.

   

• Select Go to Folder and type ~/Library/Caches/.

   

• Delete files inside each folder carefully.

   

• Repeat the same for the System Cache by typing /Library/Caches/.

   

Be sure not to delete essential system files. This method is simple and helps recover valuable space without affecting performance.

Delete Unused Apps and Files

Old or rarely used apps take up more space than you might think. Removing them is another great way to make room for updates. To uninstall them properly:

• Open Applications in Finder.

   

• Drag unwanted apps to the Trash.

   

• Don’t forget to empty the Trash afterwards.

   

Also, check for duplicate photos, videos, or documents that can be safely deleted. This helps improve performance and makes your Mac ready for updates.

Use External Storage

When your Mac’s internal storage is almost full, an external device can save the day. You can move large files, backups, or media folders to an external hard drive or USB stick. This is especially useful if you are wondering how to clear space for a macOS update without deleting important files. Just connect your external drive, move your heavy files, and start your update with enough free space available.

Alternative Ways to Update with Low Space

If you still don’t have enough space after cleaning, you can try some alternative methods. Here are a few options:

• Update through macOS Recovery: Restart your Mac while holding Command + R and use the recovery mode to install the update directly.

• Use another Mac: Create a bootable installer on a USB drive and use it to update your Mac.

• Cloud Backup: Move files temporarily to iCloud to make extra room.

   

These methods can help you complete your update safely even when local storage is tight.

Best Practices for Storage Management

Keeping your Mac clean and organised ensures smoother updates in the future. Follow these best practices:

• Regularly review large files and old downloads.

   

• Use the built-in Storage Management tool under About This Mac to monitor usage.

   

• Store photos and videos in iCloud or external drives.

   

• Avoid keeping unnecessary apps.

   

• Empty your Trash every few days.

   

These habits help you stay prepared for future macOS updates and keep your system running efficiently.

Conclusion

Lack of storage should not stop you from enjoying the latest macOS features. By following these steps, you can easily free up space, organise your files, and complete the update smoothly. Whether it’s clearing cache, removing old apps, or using external storage, each small action makes a big difference. Keep your Mac well-maintained, and you’ll never have to worry about running out of space during updates again.
