Editing Star Trek project (section)

===Within Apple===
Apple's first and quickly aborted concept of porting its flagship operating system to Intel systems was in 1985, following the exit of [[Steve Jobs]]. Apple did not reattempt this effort until Star Trek, and did not launch such a product until 2006.<ref name="Hormby_2014"/>

Apple has actually shipped products based upon the concept of hybridizing System 7 into a [[operating system shell|shell application]] platform.  It was accomplished in the form of the <code>[[A/UX#Features|startmac]]</code> process and other hybridized applications launched atop its UNIX-based [[A/UX]] system.  It was also accomplished in the form of the [[Macintosh Application Environment]] (MAE), which was the functional equivalent of Star Trek plus an embedded [[Motorola 68000|68k]] emulator (as was the case with System 7 for Power Macintosh), running as an application for Solaris and [[HP/UX]].  Apple also delivered its "DOS compatible" models of Macs, which is a hybridized Mac with a [[System 7#PC compatibility|concurrently functional]] Intel coprocessor card inside. System 7 and later have always had DOS filesystem compatibility.<ref name="DOSfilesystemtechnote"/>

Although a direct x86 port of the classic Mac&nbsp;OS was never released to the public, determined users could make Apple's retail OS run upon non-Mac computers through [[emulator|emulation]].  The development of these emulation environments was said to have been inspired by the initiative shown in the Star&nbsp;Trek project.{{citation needed|date=February 2007}} Two of the more popular 68k Macintosh emulators are [[vMac]] and [[Basilisk II]], and a PowerPC Macintosh emulator is [[SheepShaver]]; each are written by third parties.

Ten years after Project Star&nbsp;Trek, it became possible to natively run [[Darwin (operating system)|Darwin]], the [[Unix]]-based core of [[Mac OS X]], on the x86 platform by virtue of its [[NeXTstep]] foundation.<ref name="Caulfield_2010"/>  This port was widely available because Darwin was [[Open-source license|open source]] under the [[Apple Public Source License]].  However, the Mac&nbsp;OS&nbsp;X [[graphical user interface]], named [[Aqua (GUI)|Aqua]], was proprietary. It was not included with Darwin, which depended on other [[window managers]] running on [[X11]] for graphical interfaces, and thus most commercial Mac OS applications cannot run natively on Darwin alone.

Apple ran a similar project to Star&nbsp;Trek for Mac&nbsp;OS&nbsp;X, called [[Marklar project|Marklar]],<ref name="Rose_2012"/><ref name="Kim_2012"/><ref name="dePlume_2002"/><ref name="Covestor_2012"/><ref name="Orlowski_2012"/> later referred to by Steve Jobs as having been the "secret double life" of the publicly Power PC-only Mac OS.<ref name="Caulfield_2010"/> This project was to retain [[OPENSTEP]]'s x86 port, keeping Mac&nbsp;OS&nbsp;X and all supporting applications (including [[iLife]] and [[Xcode]]) running on the x86 architecture as well as that of the PowerPC. Marklar was publicly revealed by Apple's CEO [[Steve Jobs]] in June 2005 when he announced the Macintosh [[Mac transition to Intel processors|transition to Intel processors]] starting in 2006.<ref name="Orlowski_2005"/>
