Creating User Accounts and Groups

Like its cousins, Windows 2000 and XP, Mac OS X is designed from the ground up to be a multiple-user operating system, thanks to powerful software underneath its flashy exterior. You can configure a Mac OS X computer so that everyone must log in—that is, you have to click or type your name, and enter a password—when the computer turns on. Upon doing so, you discover the Macintosh universe just as you left it, including these elements:

  • Your documents, files, and folders

  • Your preference settings in just about every program you use: Web browser bookmarks and preferred home page; desktop picture, screen saver, and language; icons on the desktop and in the Dock; the size and position of the Dock itself; and so on

  • Your email account(s), including personal information and mailboxes

  • Your personally installed programs and fonts

  • Your choice of programs that launch automatically at startup
