WMacintosh Guide, also referred to as Apple Guide, was Apple Computer's online help and documentation system, added to the classic Mac OS in System 7.5 and intended to work alongside Balloon Help. In addition to hypertext, indexing and searching of the text, Macintosh Guide also offered a system for teaching users how to accomplish tasks in an interactive manner. However, the process of creating guides was more complicated than non-interactive help and few developers took full advantage of its power. Apple enhanced the help system with HTML-based help in Mac OS 8.5 which worked in conjunction with Macintosh Guide providing links to Macintosh Guide sequences. Macintosh Guide was not carried over into Mac OS X, which uses an HTML-based help system.
