Mac Storage Optimization: How to Free Up Space and Improve Performance

As we save more files on our Macs, we gradually run out of storage space. However, identifying which files to keep and which ones to remove can be challenging. That’s where optimized storage comes in handy.

Optimized storage moves files to iCloud to free up local storage space automatically. It also adds a symbol to indicate the item removed, allowing you to access it later on when you’re online. macOS Big Sur has four storage optimization features to help you free up space: Store to iCloud, Optimize Storage, Automatically Empty Trash, and Reduce Clutter.

How to Check Your Mac’s Storage and Free Up Space?

You can check your Mac’s storage by going to the About This Mac section and clicking the Storage tab. This tab shows you how much space your applications, system, documents, and other files are taking up. To free up space, you can delete old or large files manually, transfer files to cloud storage or external drives or use a cleaning app like CleanMyMac X to remove junk files.

Expert Tips on Freeing Up Disk Space on Macs

Removing old and large files can significantly free up space on your Mac. Large and Old Files modules and Space Lens on CleanMyMac X help you find and delete these files effortlessly. To free up space manually, use native uninstallers or cleaning apps like CleanMyMac X to ensure that no leftover files are left behind when deleting applications and files.

How to Keep Your Mac in Excellent Condition

Maintaining your Mac by organizing files, deleting unnecessary ones, transferring data to external drives, and updating the system and applications regularly are key to keeping your Mac in excellent condition. This practice helps free up space and improve system performance.
