After syncing photos, videos, backups, and files from your iPhone or PC, many users notice that their MacBook Neo quickly runs low on storage space. Even after emptying the Trash and deleting files from the Downloads folder, the storage usage may still show a large amount of System Data in System Settings -> General -> Storage.
System Data can include:
• System cache files
• User cache files
• Application caches
• Temporary files
• System logs
• Old iOS backups
• Browser data
• Time Machine local snapshots
• Failed downloads
If your MacBook Neo storage is almost full, this guide will show you how to safely delete junk files and recover valuable disk space.

1. Enable macOS Storage Optimization Recommendations
macOS includes built-in storage optimization tools that can automatically help free up space on your MacBook Neo.
To access these recommendations: Open System Settings, go to General, click Storage. You will see several recommendations, including:

Store in iCloud
This option stores your Photos, Messages, Desktop, and Documents in iCloud to reduce local storage usage on your Mac.
Optimize Storage
Automatically removes watched Apple TV movies and TV shows from your Mac while keeping them available in the cloud for re-download.
Empty Trash Automatically
Deletes items in the Trash after 30 days to help keep storage clean.
These built-in tools are useful for managing storage before manually deleting junk files.
2. Move iPhone Backups and Photo Libraries to an External Drive
The MacBook Neo typically comes with limited SSD storage such as 256GB or 512GB. Local iPhone backups and photo libraries can consume a significant amount of space over time.
Move iPhone or iPad Backups
If you back up your iPhone or iPad to your Mac, the backup files may take up dozens or even hundreds of gigabytes. The default backup location is: ~/Library/Application Support/MobileSync/Backup
To free up storage:
Connect an external hard drive or SSD, copy the Backup folder to the external drive. Remove the original backup files from your Mac after confirming the copy is successful. You can copy the backups back to your Mac whenever you need to restore your device.
Move the Photos Library to an External Drive
If you store a large number of iPhone photos and videos in the Photos app, your Photos Library may become extremely large. Check the size of Photos Library.photoslibrary.
To save space: Connect an external hard drive, move the Photos Library to the external drive. Open the Photos app while holding the Option key, select the moved library
The macOS Photos app fully supports managing photo libraries from external storage devices.
