In addition, OS X is the only UNIX environment that natively runs Microsoft Office, Adobe Photoshop, and thousands of other consumer applications—all side by side with traditional command-line UNIX applications. Tight integration with hardware— from the sleek MacBook Air to the powerful Mac Pro—makes OS X the platform of choice for an emerging generation of power users. This document explores the powerful industry standards and breakthrough innovations in the core technologies that power Apple’s industry-leading user experiences. We walk you through the entire software stack, from firmware and kernel to iCloud and devel- oper tools, to help you understand the many things OS X does for you every time you use your Mac.

Sharing Mac® Files on Windows® Servers a Technical Best Practices Whitepaper

WHITE PAPER The Best of Both Worlds: Sharing Mac® Files on Windows® Servers A Technical Best Practices Whitepaper About This Document Apple’s® Mac® OS X computer platform has seen its market share grow rapidly in Enterprise environments recently. This has been driven by the popularity of innovative products like the iPhone® and the MacBook Air, as well as Mac OS X’s security and its ability to run virtualized instances of Windows® applications. As a result, Macs are entering the Enterprise through senior level executives or formal corporate pilot projects. Laura DiDio from industry consultancy Information Technology Intelligence Corporation released a survey in late 2008 that showed 68% of some 700 companies polled planned to allow their end-users to deploy Macs as their work systems in the next 12 months. Separately, a recent survey by the Enterprise Desktop Alliance showed that 91% of IT administrators indicated that integration and management parity between Macs and PCs were major issues of importance to their organization. This whitepaper discusses the issues involved in sharing files between Macs and Windows servers and compares the options for successful integration. It is intended for systems administrators, technical evaluators and decision-makers who are considering upgrading or purchasing GroupLogic’s ExtremeZ-IP® solution for the first time. Overview While Apple’s Xserve provides a pure Mac file server solution, most organizations use Windows file servers. Additionally, the official Xserve end-of-life was declared by Apple in January 2011 and Apple no longer offers a server-grade, rack- mountable hardware solution. Existing investments in Windows technology and training, heavy usage, a high volume of users, virtualization and cluster environments often mean that changing a company’s IT strategy is neither economically nor politically feasible.
