NeXTSTEP is a discontinued

BSD. It was developed by NeXT Computer, founded by Steve Jobs, in the late 1980s and early 1990s and was initially used for its range of proprietary workstation computers such as the NeXTcube. It was later ported to several other computer architectures
.

Although relatively unsuccessful at the time, it attracted interest from computer scientists and researchers. It hosted the original development of the Electronic AppWrapper,[1] the first commercial electronic software distribution catalog to collectively manage encryption and provide digital rights for application software and digital media, a forerunner of the modern "app store" concept. It is the platform on which Tim Berners-Lee created the first web browser, and on which id Software developed the video games Doom and Quake.[2][3]

In 1996,

Apple Computer acquired NeXT. Apple needed a successor to the classic Mac OS, and merged NeXTSTEP and OpenStep with the Macintosh user environment to create Mac OS X. All of Apple's subsequent platforms since iPhone OS 1 were then based on Mac OS X (later renamed macOS
).

Overview

NeXTSTEP (also stylized as NeXTstep, NeXTStep, and NEXTSTEP[4][5]) is a combination of several parts:

NeXTSTEP is a preeminent implementation of the last three items. The toolkits are the canonical development system for all of the software on the system.

It introduced the idea of the

graphics primitives, internationalization, and modern typography
, in a consistent manner across all applications.

Additional kits were added to the product line. These include Portable Distributed Objects (PDO), which allow easy

object-relational database system. The kits made the system particularly interesting to custom application programmers, and NeXTSTEP had a long history in the financial programming community.[4]

History

NeXTSTEP was built upon Mach and BSD, initially

HP PA-RISC
-based systems.

NeXT separated the underlying operating system from the application frameworks, producing

4.4BSD while assimilated into Apple's development of Rhapsody for x86 and PowerPC. NeXTSTEP's direct descendant is Apple's macOS, which then yielded iPhone OS 1, iOS, iPadOS, watchOS, and tvOS
.

Legacy

The first web browser, WorldWideWeb, and the first app store[7] were all invented on the NeXTSTEP platform.

1990 CERN: A Joint proposal for a hypertext system is presented to the management. Mike Sendall buys a NeXT cube for evaluation, and gives it to Tim Berners-Lee. Tim's prototype implementation on NeXTSTEP is made in the space of a few months, thanks to the qualities of the NeXTSTEP software development system. This prototype offers WYSIWYG browsing/authoring! Current Web browsers used in "surfing the Internet" are mere passive windows, depriving the user of the possibility to contribute. During some sessions in the CERN cafeteria, Tim and I try to find a catching name for the system. I was determined that the name should not yet again be taken from Greek mythology. Tim proposes "World-Wide Web". I like this very much, except that it is difficult to pronounce in French...

— Robert Cailliau, 2 November 1995[8]

Some features and

keyboard shortcuts now common to web browsers originated in NeXTSTEP conventions. The basic layout options of HTML 1.0 and 2.0 are attributable to those features of NeXT's Text class.[9]

flow charts. This basic design can be enhanced by the simple addition of new links and new documents, located anywhere in the local area network, that foreshadowed Tim Berners-Lee's initial prototype that was written on NeXTSTEP in October–December 1990.[citation needed
]

In the 1990s, the pioneering PC games Doom, Doom II, Quake, and their respective level editors were developed by id Software on NeXT machines. Other games based on the Doom engine such as Heretic and its sequel Hexen by Raven Software, and Strife by Rogue Entertainment were developed on NeXT hardware using id's tools.[10]

Mathematica, and the advanced spreadsheet Lotus Improv, were developed using NeXTSTEP. The software that controlled MCI's Friends and Family calling plan program was developed using NeXTSTEP.[11][12]

About the time of the release of NeXTSTEP 3.2, NeXT partnered with

Mach kernel. NeXT's implementation is called "OPENSTEP for Mach" and its first release (4.0) superseded NeXTSTEP 3.3 on NeXT, Sun, and Intel IA-32
systems.

Following an announcement on December 20, 1996,

Mac OS X,[14] and eventually of iOS, iPadOS, watchOS, and tvOS
.

GNUstep is a free software implementation of the OpenStep standard.[15]

Delivered on 2 CDs: NeXTSTEP

RISC. The Developer CD includes libraries for all architectures, so that programs can be cross-compiled
on any architecture for all architectures.

4.0 beta 1996 CD-ROM m68k, i386, SPARC, PA-RISC Very different user interface.[19][20] Notable as being a precursor of many ideas later introduced in the macOS Dock.

Allegedly dropped due to complaints of having to re-teach users but not for technical reasons (the new UI worked well in the beta).
