How to Clear Cache on Mac and Free Up Gigabytes of Space
Is your Mac storage full? Before you start deleting photos or uninstalling apps, look at your cache. Cached files quietly pile up in the background and can eat gigabytes of disk space — a real problem on a 256 GB MacBook.
The good news: clearing your cache is one of the fastest ways to free up space on a Mac. Here's how to do it in seconds.
What Is Cache — and Why Does It Eat So Much Space?
Cache files are temporary data that macOS and your apps create to load faster. Your browser caches images and pages, your apps cache thumbnails and downloads, and developer tools like Xcode can cache 20+ GB without you ever noticing.
The problem is that most of this cache is never cleaned up automatically. Months later, it's still sitting on your disk — long after it's stopped being useful. On a smaller drive, that's the difference between "disk almost full" and plenty of room to work.

Scan, review, and clean — reclaiming gigabytes of cached files with VaultSort's Cache Cleaner.
How to Clear Your Cache on Mac (Step by Step)
The safest, fastest way to clear cache on a Mac is with a dedicated cache cleaner that shows you exactly what it's removing before it deletes anything. Here's the full flow in VaultSort:
- Open VaultSort
- Go to System Resources
- Open Analysis → Clean Up
- Click Scan
- Click Clean Selected Items
That's it. VaultSort scans your Mac for safe-to-remove cache, shows you what it found, and reclaims the space in a few clicks — no Terminal commands and no tech skills required.
Is It Safe to Clear Cache on Mac?
Yes — cache is temporary by design. When an app needs cached data again, it simply rebuilds it. The one thing to avoid is blindly deleting folders inside ~/Library/Caches/, where a wrong move can affect a running app.
That's why a cache cleaner that lets you review before you delete is the safer route: you see what's being removed, and only cached, safe-to-delete items are selected.
The Manual Alternative
If you'd rather do it by hand, you can:
- Clear your browser cache: Chrome alone can hold 2–5 GB. Go to your browser's Privacy or History settings and clear cached images and files.
- Clear app caches: Open Finder → Go → Go to Folder and enter
~/Library/Caches/. Move items to Trash carefully, then empty the Trash. - Clear Xcode data (developers): Delete
~/Library/Developer/Xcode/DerivedData, which often frees 20+ GB.
The manual route works, but it's slow and easy to get wrong. Scanning once and cleaning with one click is faster — and safer.
Free Up Even More Space
Cache is usually the biggest quick win, but it's not the only one. Once your cache is clear, check for duplicate files, forgotten downloads, and old iOS backups too. Our full guide to freeing up space on a Mac walks through every source of hidden storage.
