How to Find What Is Taking Up Space on Mac

Your Mac's storage can fill up quickly from large files, app caches, and forgotten downloads. macOS includes powerful built-in tools to identify storage hogs and reclaim disk space.

1. Open Storage Management. Click the Apple menu → About This Mac → Storage Settings. This opens the comprehensive storage breakdown showing how your disk space is allocated across categories like Applications, Documents, iOS Files, and System Data.
2. Review storage categories. Examine the color-coded storage bar to identify the largest categories. Click any category to drill down into specific files and folders. Documents typically contains user files, while System Data includes caches and temporary files.
3. Use built-in recommendations. Click the 'Recommendations' button to see macOS suggestions for freeing space. Options include storing files in iCloud, emptying trash automatically, and reducing clutter. Each recommendation shows potential space savings.
4. Analyze large files with Finder. Open Finder and press Command+F to search. Set the first dropdown to 'File Size' and select 'is greater than' with a value like 1 GB. This reveals the largest files consuming your storage across all locations.
5. Check Downloads and Desktop. Navigate to Downloads folder and sort by size (View → as List, then click Size column header). Large installer files, disk images, and old downloads accumulate here. Review Desktop for forgotten large files.
6. Clear application caches. Open Finder and press Command+Shift+G, then type ~/Library/Caches. Review folders for applications you use heavily—browsers, video editors, and creative apps often store gigabytes of cache data here.
7. Monitor ongoing storage usage. Add the storage indicator to your menu bar by opening System Settings → Control Center → Menu Bar Only → Battery → Show Percentage. This provides quick access to storage information without opening multiple windows.
