Performing routine housekeeping chores on the MacBook is a necessary function that can help free up extra space on your hard drive and keep your folders uncluttered. When your MacBook's hard drive bloats up with unnecessary files, movie clips or utilities that are not in use you can easily delete them with a few simple steps.
Click "Go" from the Finder menu. Scroll down to "Applications" or "Utilities" and select the files you want to delete. Alternatively, display the file you want to delete in a Finder window.
Drag the file's icon or name to the trash then release the mouse. Alternatively, right-click on the icon or file name then select "Move to Trash" from the drop-down menu. Click on the file name or icon then press "Command" + "Delete."
Select "Empty Trash" from the "Finder" menu to regain hard drive space.
