Recent versions of Mac OS X and macOS have started to hide the root folder from users (the root folder is the folder at the root of your hard drive). To make the root folder appear, follow these steps:
- anywhere on the Desktop, enter Command+Shift+G, then type / and hit return. This will take you to root (Macintosh HD)
- drag & drop Macintosh HD into the Finder sidebar.
You may also want to display Macintosh HD on your Desktop. In this case, open the Finder menu and choose « Preferences ». Under the « General » tab check the box next to « Hard disks ». This will show Macintosh HD.
