In macOS Big Sur major changes in the user interface, support for iOS, and iPadOS apps are made. Apple no longer supports 32-bit (x86) applications anymore. That is the end for both Intel processors in addition to x86 architecture-based computers as well. But now, Apple has made an OS compatible with Apple’s Silicon. For years, Apple was using IBM PowerPoint architecture to the x86 architecture and Intel processors inside their system. The reason behind the change in version was due to the transition of Macintosh into a new CPU architecture. Almost more than 20 years, Apple was running the OS-X series but now it is the end. First,macOS X was introduced in 2000 as Mac OS X Public Beta, who later was succeeded by Mac OS X Cheetah. macOS Catalina 10.16 is the last version of the macOS X series.įor the first time, Apple has changed the macOS series from X (10) to 11. macOS Big Sur is the successor of macOS Catalina and the end of OS-X series. It is the first release of macOS with the primary number “11”. Mavericks was the first OS in the macOS series with the region name. The custom started after the end of Mac OS X ( Mountain Lion). As it looks, Apple will use the name of different regions of California as the name of their OS.
