In versions of the Mac OS prior to Mac OS 8, the Guide menu (marked with the icon shown in Figure 1) appeared just to the left of the Application menu (in the upper-right corner of the screen). The Guide menu contains onscreen help and information and is your main source of information when working with your computer. With the release of Mac OS 8, the Guide menu is now a menu called Help. This menu has been moved from the upper-right corner of the screen to the last menu (from left to right) in the Finder or an application.

Apple Video Player 1.6.3 and later installs 2 invisible menus between the Windows and Help menus for compatibility with Apple Guide. Prior to Mac OS 8, users did not see these invisible menus. These invisible menus do not cause any known usability or compatibility issues.
