My Mac Mini Finder Has No Sidebar
- The Mac Mini is 1.4 inches high by 7.7 inches deep and 7.7 inches wide, and weighs 3 pounds. It comes with a 320GB or 500GB hard drive, depending on the configuration, and an optical drive for reading and writing CDs and DVDS. The Mini Mac has four USB 2.0 ports, one FireWire 800 port and an SD card slot.
- You use the Finder on your Mac Mini to work with files, folders, applications, mounted drives and aliases, or shortcuts to items such as files, folders and applications. Click "File" from the Finder menu, and then click "New Finder Window" to create a window that you use to browse files and folders on your Mac Mini.
- Each Finder window displays items in your computer in a list, by icons, in column view or with Cover Flow, a graphical way to browse your files. The sidebar appears on the left side of a Finder window. It shows each mounted device under "Devices," and various folders and files under "Places." For example, you can click on "Applications" under "Places" to switch the Finder window to display the contents of your Applications folder. Drag a file or a folder into the sidebar to create a shortcut to it, which you can access with any Finder window.
- You can configure each Finder window on your Mac Mini's desktop separately, such as sorting the contents of one by date, and another by name, or having the Sidebar active in one window and disabling the Sidebar in windows where you want more room to display the files. Click "View" from the Finder menu, and then click "Show Sidebar" to show the Sidebar in any Finder window. Click "View," and then click "Hide Sidebar" to make a Finder window's sidebar disappear.
