How to Remove Data from Your Mac

Once you've identified the largest unused storage areas, you can begin removing unwanted files and applications.

Delete Files

  1. Open Finder and locate large or unneeded files.
  2. Right-click the file and choose Move to Bin.
  3. Open the Bin from your Dock and click Empty (top-right corner).

⚠️ Important: Moving files to the Bin doesn’t free up space until the Bin is emptied.

Remove Applications

  1. Open Finder.
  2. Click Applications in the sidebar.
  3. Right-click the app you want to remove and choose Move to Bin.
  4. Empty the Bin to permanently delete the app.

💡 Tip: Enable Auto-Empty Bin

  1. Go to System Settings > General > Storage.
  2. Toggle on Empty Bin Automatically to auto-delete items after 30 days.

Alternative Storage Options

Use an External Drive

  1. Plug in your external drive and select Trust if prompted.
  2. Open Finder and drag files to the external drive.
  3. Verify the transfer is complete.
  4. Delete the original files from your Mac to free up space.

Use Cloud Storage

Services like iCloud, Dropbox, or Google Drive allow you to offload files without permanently deleting them:

  • Your files remain accessible across all devices.
  • Files stored in the cloud don’t take up space on your local disk.
