How to Free Up Other Storage on Mac

Mac computers often show a large “Other” category in storage measurements, which can be mysterious and hard to reclaim. This guide explains practical steps to identify and reduce space taken by non-system files, caches, and duplicated data while using trusted tools to keep the Mac running smoothly.

Quick Answer

To reclaim space from “Other” on Mac, run a reputable Mac disk space analyzer software to locate large files, use a duplicate file finder for Mac to remove redundancies, and apply a Mac cleaner utility storage or Mac cache cleaner tool to safely purge caches. Regular backups with an external hard drive for Mac backup ensure data safety during cleanup.

Before You Start

Prepare by backing up important data to an external drive or cloud storage. Review which folders contribute to “Other”—including system caches, application support files, and disk images. Never delete files you don’t recognize, as essential system components may reside there. Allocate at least 1–2 hours for a thorough pass, and perform cleanup when you don’t need immediate access to large files.

Step-By-Step: How To Free Up Other Storage On Mac

Open your Mac disk space analyzer software to get a visual map of storage usage and identify top contributors to the “Other” category.
Use the tool’s filters to isolate large non-user files, old DMG and ISO images, and leftover installers.
Run a duplicate file finder for Mac to locate and safely remove redundant copies of files across your user folders and app directories.
Inspect application support and caches with a Mac cleaner utility storage, focusing on old cache files and logs that are safe to purge.
Clear browser caches and temporary files if the analyzer flags them as consuming space, then confirm the cleanup within the tool’s prompts.
Review large saved app states and old iOS backups that may reside in the user Library or MobileBackups; delete or move to an external backup if needed.
Consider relocating large, infrequently used files to an external hard drive for Mac backup and remove local copies to reclaim space.
Empty the Trash from both the user account and the system level after deleting or moving files.
Run a final pass with the disk space analyzer to verify that the “Other” category decreased and no essential items were removed.
Set up ongoing maintenance: schedule periodic scans and consider automating cache cleanup with trusted utilities.
If space remains stubborn, review Time Machine local snapshots and disable local backups if appropriate, then recheck storage usage.

Troubleshooting

Symptom	Likely Cause	Fix	Prevention
Space in “Other” doesn’t decrease after cleanup	Persistent system files or misclassified data	Re-scan with disk space analyzer and review system folders carefully	Regularly purge temp files and maintain a clean backup regimen
Unable to delete certain files	Permissions or active processes	Change permissions or quit related apps, then try again	Avoid deleting system-critical files
Large caches reappear quickly	Active apps recreate caches	Set up periodic cache cleanups and app-level preferences	Limit cache growth by adjusting app settings where possible
Backup space is insufficient	Backups taking space on the primary drive	Move backups to an external drive or partition	Keep only necessary restore points

Common Mistakes

Deleting files without confirming their purpose, risking app instability
Over-reliance on a single cleaner tool; combine strategies for best results
Ignoring time-based backups and local snapshots that occupy space

Careful verification and staged cleanup prevent unintentional data loss while reclaiming storage.

Tips For Best Results

Run disk space analysis on a fresh user session to avoid counting active files inaccurately
Schedule periodic cleanups, e.g., monthly, to manage “Other” growth
Use a reputable Mac disk space analyzer software with a clear visualization of large directories
Keep a verified external hard drive for Mac backup and rotate backups to protect data

Call A Professional

Contact a professional if you encounter corrupted files, persistent disk errors, or inability to access critical system data. Seek expert help if you notice hardware-related storage issues, such as failing drives, unusual noises, or frequent crashes that persist after cleanup attempts.

FAQ

What exactly is “Other” storage on Mac?

“Other” is a catch-all category for data that doesn’t fit into apps, photos, or system files, including caches, app support files, disk images, and documents.

Can I safely delete all caches to free space?

Not all caches are safe to delete; use a trusted cleaner and selectively purge non-essential caches after confirming they won’t affect performance.

How often should I run a disk space cleanup?

For most users, monthly cleanups or after major downloads and installs help maintain free space.

Is it okay to delete old backup files from the Mac?

Only delete backup files if you have a newer, verified backup available and you understand what will be removed.

What if Cleanup Doesn’t Reduce “Other”?

Investigate hidden or system-related files with caution and consider professional evaluation if the issue persists.

Do I need an external drive for backups?

Yes, using an external drive provides a safe, separate location for backups and can help free local storage.

Will these tools harm my Mac?

When sourced from reputable developers and used as intended, these tools minimize risk and improve storage management.

Buying Guide

Choosing the right tools and setup helps sustain free space over time. Consider the following factors:

Size and scope: For large systems, pick a robust disk space analyzer that can map usage across all drives.
Noise level: Software tools are silent; hardware backups may require a quiet external drive if placed in workspaces.
Energy efficiency: Software operations don’t affect power, while backups on external drives can impact energy usage during long transfers.
Controls: Look for intuitive interfaces, batch cleanup capabilities, and safe recovery options.
Placement: Keep external backup drives in a cool, secure location; label them for easy identification.

When evaluating options, compare how each tool handles duplicates, caches, and large files without compromising system integrity. A combination of a Mac disk space analyzer software, a duplicate file finder for Mac, and a Mac cleaner utility storage typically provides a balanced approach. Pair this with an external backup solution to safeguard data while reclaiming space.
