Default Macintosh HD icon
Macintosh HD is the default name for the hard drive on many Mac models. Historically, the Macintosh HD icon was present at the top right corner of the desktop of new Macintosh computers, though recent versions of macOS hides this from new users by default. Double-clicking on it opens a zooming Finder window, which displays the files and folders lying on your hard drive. As of Mac OS X 10.4 "Tiger", the Macintosh HD icon also lies underneath the Network entry, and above the CD/DVD Drive icon, in the Finder sidebar.
