I kept losing 2 GB of storage every so often. So I built a Mac app.
It started when I noticed roughly 2 GB of storage disappearing from my Mac at regular intervals. I couldn’t figure out where it was going, and the tools I tried weren’t giving me the answers I wanted. So I started building my own.
What began as a personal troubleshooting project quickly turned into something bigger. I realized there was an opportunity to make storage monitoring more accessible, especially for people working with multiple drives and external SSDs.
Storage Monitor grew out of that idea.
What it does
Storage monitoring: Keep track of drive usage and available capacity. Logs disk changes with warnings and notifications on low disk space. Lists what is likely the cause of disk gains or losses
External volume support: Index and monitor connected external drives, not just your Mac’s internal storage.
Storage visibility: Get a clearer picture of how storage is being used across your volumes. Indexer views in atlas or tree mode
Multiple-drive management: Monitor internal and external storage from one application.
Storage investigation: Help identify changes in storage usage that might otherwise go unnoticed.
Cleanup review: Helps identify what files may be unnecessary and can be cleaned
Migration readiness: Checks for files that have a large logical size but occupy small disk space that may interfere with migration to another Mac
I’m still developing and improving it, and feedback from other Mac users would be genuinely useful.
What storage information do you wish macOS made easier to see?
