Today, Adobe FrameMaker is still a widely used publication tool for technical writers, although no version has been released for the Mac OS X operating system, limiting use of the product. The decision to cancel FrameMaker caused considerable friction between Adobe and Mac users, including Apple itself, which relied on it for creating documentation. As late as 2008, Apple manuals for OS X Leopard[6] and the iPhone[7] were still being developed on FrameMaker 7 in Classic mode; Apple has since switched to using InDesign.
