OS X Server is the next generation of Apple’s award-winning server software. OS X Server makes it easy to share files, schedule meetings, synchronise contacts, host your own website, publish wikis, configure Macs, iPhones and iPads, remotely access your network, and more. With a Volume Licence Agreement (VLA), you license the right to use OS X Server software on a specified number of computers at your business or school — you determine how many. Volume Licences start at 20 seats for OS X Server and also require the purchase of OS X Mountain Lion Volume Licence for systems not already running OS X Mountain Lion.
