Mac Os X Base System Appears To Be Ok
Mac OS X is Apple's operatingsystem for its line of Macintosh computers. Its interface, known asAqua, is built on a Unix foundation. Although ithas much of the look and feel of the former Mac OS,features such as preemptive multitasking, symmetric multiprocessing,multithreading, and protected memory give Mac OS X improved stabilityand performance. For the current version's system requirements, seeApple's Mac OS XTechnical Specifications.
Currently, four Mac OS X-related products are available:
OS X Mavericks is quite good, and is at least optimized for most hardware. On a brand new Mac, OS X Yosemite runs quite well, however. Fortunately, most 2010 Macs came with physical reinstall DVD volumes of Mac OS X Snow Leopard, so you should be good to go with that.

Mac Os X Based On
Mac OS X Leopard (version 10.5) is the sixth major release of macOS, Apple's desktop and server operating system for Macintosh computers. Leopard was released on October 26, 2007 as the successor of Mac OS X 10.4 Tiger, and is available in two editions: a desktop version suitable for personal computers, and a server version, Mac OS X Server. In fact, you can see Mac OS X Base System in Disk Utility (under Recovery mode of course) but Disk Utility won't let you erase it. I'm wondering if it forms some sort of 'core' of Mac OS X Lion to use during the recovery process since when doing an Internet Recovery it says 'downloading additional components'. – Jason Waldrop Aug 24 '11 at 2:06.
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.
