Editing Mac OS X 10.0 (section)

== Development ==
The development of Mac OS X 10.0 began in 1998, after Apple acquired [[NeXT]] Computer, which was founded by [[Steve Jobs]] after he was forcibly removed from Apple in the mid-1980s.

The initial development of Mac OS X was led by [[Avie Tevanian]], who had previously worked at NeXT and had played a key role in the development of [[NeXTSTEP]]. The development team faced significant challenges in merging the classic [[Mac operating systems|Mac OS]] with the new [[Unix]]-based architecture, as well as in creating a modern user interface that would be familiar to Mac users.

Mac OS X 10.0 was released to the public on March 24, 2001, after several months of beta testing. The release was met with mixed reviews, with some users praising the new features and stability, while others criticized the lack of compatibility with older Mac applications.

Some of the key features of Mac OS X 10.0 included the [[Aqua (user interface)|Aqua]] user interface, which introduced translucent menus, drop shadows, and other visual effects; and the Dock, a new way of launching and switching between applications. The operating system also included built-in support for networking protocols such as [[Internet protocol suite|TCP/IP]] and PPP, as well as for USB and [[IEEE 1394|FireWire]] devices.

Two decades after its release, [[Bertrand Serlet]], manager of OS X Platform Technology at Apple when the early releases of Mac OS X were being developed, admitted that this version of Mac OS X had a lot of performance issues, as the OS was very slow, and expensive, so that many customers would not buy it, and be disappointed. There was six months without any new features, which was spent on performance increases, culminating in 10.1.<ref>{{Cite av media |title=Oral History of Bertrand Serlet |author=Bertrand Serlet |interviewer=Hansen Hsu|date=September 20, 2023 |time=1:45:57 |url=https://www.youtube.com/watch?v=qpIuIImN0YI}}</ref><ref>{{cite interview |title=Oral History of Bertrand Serlet |author=Bertrand Serlet |interviewer=Hansen Hsu |website=[[Computer History Museum]] |date=September 20, 2023 |pages=23-24 |url=https://www.computerhistory.org/collections/catalog/102808912}}</ref>
