OS
Apple Computer Inc. (now Apple Inc.)
introduced the Macintosh personal computer,
later retroactively renamed to the Macintosh
128K model.
January 24, 1984,
The operating system of early Macintosh is
named "System Software" or "System", and its
ensuing series was later renamed to Mac OS.
The Macintosh platform is generally credited
with having popularized the early concept of the
graphical user interface, the main recognizable
aspect of Mac OS.
The original Macintosh system software was
partially based on the Lisa OS, previously
released by Apple for the Lisa computer in
1983.
As part of an agreement allowing Xerox to buy
shares in Apple at a favorable price, it also
used concepts from the Xerox PARC Xerox
Alto, which Steve Jobs and several other
Macintosh team members had.
Mac OS has been pre-installed on almost every
Macintosh computer sold, and has been sold
separately in retail stores until being distributed
exclusively online.
Apple Inc. provides updates to the iOS
operating system for the iPhone, iPad, and
iPod Touch through iTunes, and since iOS 5.0,
also through over-the-air software updates.
With the June 6, 2011 announcement of iOS
5.0, a USB connection to iTunes is no longer
needed to activate iOS devices; data
synchronization can happen automatically and
wirelessly through Apple's iCloud service. The
most recent update, iOS 8.1, brought new
features and fixed many bugs.
Apple's iOS did not have an official name until
the release of the iPhone software
development kit (iPhone SDK) on March 6,
2008. Before then, Apple marketing literature
simply stated that their iPhone runs a version of
"OS X", a reference to iOS' parent operating
system.
When introduced, it was named iPhone OS. It
was renamed iOS on June 7, 2010, as the
iPhone was no longer the only device to run
iOS. Apple licensed the "iOS" trademark from
Cisco.
