Originally, the iOS system was called iPhone OS. Because iPad, iPhone and iPod touch all use iPhone OS, it was announced at the WWDC conference on 20 10 that it was renamed as iOS(iOS is a registered trademark of Cisco's network equipment operating system in the United States, and Apple's renaming has been authorized by Cisco).
MacOS is the world's first comprehensive operating system based on FreeBSD system and adopting "object-oriented operating system". The object-oriented operating system was developed by NeXT, which was founded after Steve Jobs was forced to leave Apple in 1985. Later, Apple acquired NeXT.
Jobs became the CEO of Apple again, and the Mac OS system that Mac started to use was integrated into the Openstep system developed by NeXT.
