Incorporating the Mac into an existing PC network is easier than ever with Mac OS X. Native support for Mac- and Windows-based networks means that you don't have to deal with compatibility issues and you can leverage your existing technology investments. The Mac can connect to virtually any server, share files with nearly any computer, and seamlessly share printers and other network services. It can even authenticate to Active Directory services. With Mac OS X, the Mac has out-of-the-box support for Microsoft Exchange Server 2007, something even Windows PCs don't have.
