Apple is expected to launch its next generation Leopard operating system (OS) in April, but according to industry sources, the release of the new OS will be postponed to October to allow Apple to make Leopard support Windows Vista through an integrated version of its Boot Camp software.
The sources pointed out that the launch delay is not due to software design problems with Leopard but instead is attributed to Apple's plan to have its new OS support Windows Vista through an integrated version of Boot Camp. Boot Camp is an Apple software application that currently assists in the installation of Windows XP on computers using Apple's latest OS. The company hopes with support for Vista, Mac computers using the new OS can grab more market share, according to the sources.
