Currently, four Mac OS X-related products are available:
Mac OS X: This is the version most Macintoshowners should use. It is a consumer operating system designed for useon your personal computer. For more information, see Apple's Mac OS X page and Developer page forMac OS X.
Mac OS X Server: This is Apple's server operatingsystem. It is similar to the consumer release of Mac OS X, but alsoincludes a suite of network services, such as a print server, filesharing, QuickTime streaming, NetBoot, and advanced webhosting. For more information, see Apple's Mac OS X Server page.
iOS: Based on Mac OS X, versions of iOS run on theiPhone, the iPod touch, and the iPad. The iOS was designed forhandheld devices, and is much more tightly controlled than otherversions of Mac OS X. Despite their shared origins, applications(apps) developed for iOS are not compatible with Mac OS X, and viceversa.
Darwin:Darwin is the Unix-likefoundation upon which Mac OS X is based. Its code is opensource, and it is available as a stand-alone operatingsystem. Although Darwin will run many Unix applications, including theX Window System, it does not have the Mac OS X interfaceand thus will not run Mac OS X applications. For more information, seeApple's Developer Open Sourcepage.
