Is there any difference between Mac OS X and macOS?

Yes, there is a difference between Mac OS X and macOS. macOS is the new name for the operating system that came with Apple’s latest desktop computer, the Mac Pro. Mac OS X was the name of the operating system that was used before that.

One big difference between Mac OS X and macOS is that macOS comes with a new user interface called High Sierra. This interface looks different from the older interfaces and it’s easier to use. You can use it to work on your computer and to keep track of your files. MacOS also comes with many new features, including security improvements, better performance, and more compatibility with other programs.

List of macOS versions

macOS is a line of the desktop, laptop, and tablet operating systems developed and marketed by Apple Inc. since 2001. macOS versions span 11 years of software releases, from 10.6 Tiger (10.6.8) through High Sierra (10.13). Of these versions, 10.12 Sierra was the last major release to support 32-bit Intel processors only. Starting with macOS Mojave (10.14), all macOS releases are 64-bit only and require at least an 8th generation Core i5 or Core i7 processor to run.

Notable features of macOS include Continuity features, which lets users access their devices’ data across multiple devices; FileVault 2 encryption for protecting user data on Macs; System Integrity Protection, which prevents malicious applications from modifying critical system files; Gatekeeper, which helps to protect users from installing unauthorized software; and Activation Lock, which requires a fingerprint or face scan to be used on a device in order to make changes to its settings or use it without approval from the owner.
