How to clear the cache on your Mac — safely

Apps store temporary files in ~/Library/Caches to load faster. Over time those caches balloon to gigabytes, and stale ones can even cause glitches. Clearing them is safe — apps rebuild what they need — but doing it by hand risks deleting the cache of an app that's open.

The manual way (and its risk)

You can open Finder, press ⇧⌘G, go to ~/Library/Caches and delete folder contents. The danger: if you clear the cache of a running app, you can crash it and lose unsaved work.

The safe, one-click way

CleanerMac scans your app and system caches and clears them in one click — and it automatically skips any app that's currently open, matching cache folders to running apps by bundle id. Everything goes to the Trash, so it's recoverable.

What it clears

• Application caches (~/Library/Caches)
• System & app logs (~/Library/Logs)
• Developer build caches, with active projects protected

Clear your cache the safe way

One click, open apps protected, fully recoverable.
