1.1 How many versions of R for Mac OS X? There is only one version of R for Mac OS X. However, R on Mac OS X can be used either on the command-line as on other Unix systems, or via the R.APP GUI (see R.app).The second approach is mostly preferred by Macintosh users. Global Nav Open Menu Global Nav Close Menu; Apple; Shopping Bag +. Mac OS X was originally presented as the tenth major version of Apple's operating system for Macintosh computers; current versions of macOS retain the major version number '10'. Previous Macintosh operating systems (versions of the classic Mac OS ) were named using Arabic numerals, as with Mac OS 8 and Mac OS 9.
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:
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.

Have you noticed that once Apple releases a new version of the Mac operating system (macOS) that previous versions vanish from the App Store? Have you ever needed to reinstall one of these older versions of the Mac operating system (macOS)? It can be challenging to do this since Apple does not make older versions readily available unless you saved your own copy of the installer for the older version. I recently learned that some older versions are still available on the App Store.
Mac Os Catalina
[UpdateOctober2019 – Apple now offers a more straight forward way to download older versions of the Mac operating system (macOS) going back to OS X Yosemite (aka OS X 10.10).

List Of Mac Os Releases
This article on wphosting.tv has links for downloading some older versions of the Mac operating system (macOS). If you think you might ever need to install an older version then I recommend you download the installers now and then save the installer file so you can create your own install disk, if needed. This Apple support article currently provides instructions on how you can create your own installer disk for El Capitan, Sierra, High Sierra and Mojave. Alternatively you could use an application like DiskMaker X.
As of February 2019, Apple has links to get these versions from the App Store:
App Store links are not provided for older versions of the Mac operating system, such as El Capitan (10.11), Yosemite (10.10) or Mavericks (10.9). This is not a surprise since Apple only officially supports and maintains the 3 most recent versions of the Mac operating system (macOS).
Links are also provided for buying an installer from Apple for Mountain Lion (10.8), Lion (10.7) and Snow Leopard (10.6) Over the decades, Apple has vacillated on whether or not they charged for the Mac operating system. The most recent vacillation came with the introduction of OS X Mavericks (aka OS X 10.9) in 2013, when Apple switched to offering it for free. Prior to that, Apple charged for the Mac operating system since the introduction of Mac OS 8 in the late 1990’s.
