Mac storage is full or almost full
Mac storage fills from downloads, app caches, and old files over time. Empty your Trash, clear your Downloads folder, and enable iCloud optimization to free significant space quickly.
Mac storage fills from accumulated downloads, app caches, and large media files. MacOS needs at least 10 percent free storage to run smoothly. Below that your Mac slows dramatically. The Storage section in System Settings shows exactly what's using space.
