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.
Is your Mac up to date with the latest version of the Mac operating system? Is it using the version that is required by a product you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, check which version is installed now.
If your macOS isn't up to date, you may be able to update to a later version.
From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article will be updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar and Photos.
