Step 1: Scan Your Mac Storage Visually
Start by downloading DiskShift and running a full scan of your Mac Home folder or Macintosh HD. DiskShift will generate an interactive treemap where block size correlates directly with file size.
Step 2: Clear Hidden System Caches & App Leftovers
Mac applications often leave behind gigabytes of cached data in ~/Library/Caches and leftover data in ~/Library/Application Support after uninstallation. DiskShift highlights these leftover blocks so you can move them to the Trash with one click.
Step 3: Remove Large Video & Archive Files
Use DiskShift's 'Large Files' filter to sort files by size (>500MB). You will often discover old video renders, 4K screen recordings, or ZIP archives you no longer need.
Step 4: Delete Duplicate Downloads
DiskShift scans your Downloads and Documents folders for duplicate files, letting you safely delete extra copies while keeping the original.
