According to Hardmac, Mac OS X Lion server will come as a paid-for downloadable app from the Mac App Store. One of Hardmac's French readers (Blaise) inadvertently stumbled across this help window when typing "install server" in the help menu of a beta build of Apple's newest, soon-to-be-released version of Mac OS X, Lion.
The help window states, "If this Mac isn't a server, you can make it one by installing the server app." It then goes on to detail the process of installing the app and creating an administrator account. The help menu ends with, "The Server app downloads the Server Essentials software package, installs it, and configures this Mac as a server."
However, as we've noted previously, Apple's own Lion marketing webpage states that "Lion Server is now part of Mac OS X Lion." It reads, "It's easy to set up your Mac as a server and take advantage of the many services Lion Server has to offer."
Being that Apple currently charges US$499 for its Snow Leopard server package, it's conceivable that Apple may charge something extra to flip Lion's server switch via the Mac App Store. But we're unconvinced.
Mac OS X Lion, alongside iCloud and iOS 5, is scheduled to be introduced on June 6th by Steve Jobs at Apple's World Wide Developer's Conference.
