Apple is adding even more to its free software list, although this time you'll need to be part of the company's developer program. OS X Server for Mavericks, regularly priced at US$19.99, is free for developers as part of a move to help coders create bots that auto-test and analyze their apps.
Apple gives iOS app developers Mavericks Server for free
By giving away Mavericks Server, Apple is potentially making it easier for developers to take advantage of the new automation features built into Xcode, which is the Mac-based development platform for iOS and OS X apps. Through automated bots, the theory goes, developers can catch bugs before their apps hit the App Store, and they can speed up their coding workflow.
Apple started shipping OS X Mavericks and OS X Server for Mavericks on Tuesday. The standard version of Mavericks is free while the server upgrade costs $19.99.
