Libor Kubín Kusukela ngo-1984, iMacintosh ibisebenzisa iSystem. Ekuqaleni kwawo-90, kwaba sobala ukuthi isistimu yokusebenza ekhona idinga ukuqanjwa okusha okuyisisekelo. I-Apple yamemezela uhlelo olusha lwesizukulwane ngoMashi 1994 ngokwethulwa kweprosesa ye-PowerPC ICopland.
Naphezu kwesabelomali esivulekile (amaRandi ayizigidi ezingu-250 ngonyaka) kanye nokuthunyelwa kwethimba lonjiniyela bezinhlelo zokusebenza abangu-500, i-Apple ayikwazanga ukuqedela umsebenzi. Intuthuko yayihamba kancane, kwaba khona ukubambezeleka nokungalandelwa kweminqamulajuqu. Ngenxa yalokhu, ukuthuthukiswa okuncane (okutholakala eCopland) kwakhululwa. Lezi ziqale ukuvela ku-Mac OS 7.6. Ngo-August 1996, i-Copland yagcina imisiwe ngaphambi kokukhululwa kwenguqulo yokuqala yokuthuthukiswa. U-Apple wayefuna ozongena esikhundleni, futhi i-BeOS yayiyikhandidethi elishisayo. Kodwa ukuthengwa akwenziwanga ngenxa yezidingo zezimali ezeqile. Kube nomzamo wokusebenzisa, isibonelo, i-Windows NT, i-Solaris, i-TalOS (kanye ne-IBM) ne-A/UX, kodwa ngaphandle kwempumelelo.
Isimemezelo sango-December 20, 1996 samangaza wonke umuntu. U-Apple uthenge Olandelayo ngemali engu-$429 million. USteve Jobs waqashwa njengomeluleki futhi wathola amasheya e-Apple ayizigidi ezingu-1,5. Umgomo oyinhloko walokhu kutholwa kwakuwukusebenzisa i-NEXTSTEP njengesisekelo sesistimu yokusebenza yesikhathi esizayo yamakhompyutha e-Macintosh.
Mashi 16, 1999 ikhishwe I-Mac OS X Server 1.0 eyaziwa nangokuthi i-Rhapsody. Ibukeka njenge-Mac OS 8 enetimu yePlatinum. Kodwa ngaphakathi, isistimu isekelwe kungxube ye-OpenStep (NeXTSTEP), izingxenye ze-Unix, i-Mac OS, ne-Mac OS X. Imenyu engaphezulu kwesikrini ivela ku-Mac OS, kodwa ukuphathwa kwefayela kwenziwa kokuthi I-Workspace Manager ye-NEXTSTEP esikhundleni salokho. yoMtholi. I-interface yomsebenzisi isasebenzisa i-Display PostScript ukuze iboniswe.
Inguqulo yokuqala ye-beta yomsebenzisi ye-Mac OS X (i-codenamed Kodiak) yakhululwa ngoMeyi 10, 1999. Yayihloselwe onjiniyela ababhalisiwe kuphela. NgoSepthemba 13, inguqulo yokuqala ye-beta yomphakathi ye-Mac OS X yakhululwa futhi yathengiswa ngo-$29,95.
Uhlelo lulethe izinto ezintsha eziningi: umugqa womyalo, inkumbulo evikelwe, ukwenza izinto eziningi, ukusetshenziswa komdabu kwamaphrosesa amaningi, i-Quartz, idokhi, isikhombimsebenzisi se-Aqua esinezithunzi nokusekelwa kwe-PDF kwezinga lesistimu. Nokho, i-Mac OS X v10.0 ibintula ukudlalwa kwe-DVD nokushiswa kwe-CD. Bekudinga iphrosesa ye-G3, 128 MB ye-RAM kanye no-1,5 GB wesikhala samahhala sediski eligcinalwazi ukuze kufakwe. Ukuhambisana okusemuva nakho kwaqinisekiswa ngenxa yamathuba okusebenzisa i-OS 9 nezinhlelo eziklanyelwe yona ngaphansi kongqimba lwakudala.
Inguqulo yokugcina ye-Mac OS X 10.0 yakhululwa ngo-March 24, 2001 futhi yabiza u-$129. Yize lolu hlelo beluqanjwe ngeCheetah kodwa aliphumelelanga ngejubane noma ngokusimama. Ngakho-ke, ngoSepthemba 25, 2001, yathathelwa indawo ukuthuthukiswa kwamahhala ku-Mac OS X 10.1 Puma.
Iyini i-Mac OS X
Isistimu yokusebenza esekelwe ku-hybrid XNU kernel (ngesiNgisi XNU's Not Unix), eyakhiwe i-microkernel ye-Mach 4.0 (ixhumana ne-hardware futhi inakekele ukuphatha inkumbulo, imicu nezinqubo, njll.) kanye negobolondo efomini. yeFreeBSD, ezama ukuhambisana nayo. Umnyombo kanye nezinye izingxenye zakha uhlelo lukaDarwin. Nakuba uhlelo lwe-BSD lusetshenziswa kusisekelo, isibonelo i-bash ne-vim isetshenziswa, nakuba ku-FreeBSD uzothola i-csh ne-vi.1
