How to Clear Out Unwanted Files on MacBook (4 Steps)

Click the Finder icon in your Dock to open a new Finder window and locate the files you want to remove from your MacBook.
Drag and drop the files into your Trash. To drag and drop, click a file and, still holding your mouse, move it to your Trash icon. Release the mouse when the file is directly over the icon to drop it in your Trash. You can also select 'File' from your MacBook's top menu bar, then select 'Move to Trash.'
Click your Trash icon and hold it until the Options menu pops up. Select 'Empty Trash.' Confirm that you want to empty your Trash when prompted by the Finder.
Select 'File' from the top menu bar, then select 'Secure Empty Trash' to permanently empty your Trash. If you are using Mac OS X v10.6, also known as 'Snow Leopard,' performing the Secure Empty Trash function will remove the 'Put Back' option to recover deleted files. The Secure Empty Trash function can take anywhere from several minutes to up to an hour, depending on the last time you performed the function and how many files are in your Trash.
