Getting information on a file, folder, drive, or device on the Mac is straightforward:

  • Go to the Finder.
  • Click once to select an item.
  • Press Command I for information.
  • The information box opens.
  • When you are finished, click the red candy button in the top left-hand corner of the information box to close it.

You do not have to be in the Finder to use Command I. It will work on any item you select in a folder, or on the desktop.

Although the information box has a single format, the data shown is specific to the type of item selected, e.g.; file, folder, drive or device.
