Libor Kubin Txij xyoo 1984, Macintosh tau siv System. Txawm li cas los xij, thaum ntxov xyoo 90, nws tau pom tseeb tias qhov kev khiav hauj lwm uas twb muaj lawm xav tau kev tsim kho tshiab. Apple tshaj tawm cov txheej txheem tshiab nyob rau lub Peb Hlis 1994 nrog kev tshaj tawm ntawm PowerPC processor Pob Tsuas.
Txawm hais tias muaj kev siv nyiaj ntau ($ 250 lab ib xyoos) thiab kev xa tawm ntawm pab pawg ntawm 500 software engineers, Apple tsis tuaj yeem ua tiav qhov project. Kev txhim kho tau qeeb, muaj kev ncua thiab tsis ua raws li lub sijhawm kawg. Vim li no, kev txhim kho ib nrab (los ntawm Copland) raug tso tawm. Cov no pib tshwm los ntawm Mac OS 7.6. Thaum lub Yim Hli 1996, Copland thaum kawg tau nres ua ntej tso tawm thawj qhov kev txhim kho version. Apple tab tom nrhiav kev hloov pauv, thiab BeOS yog tus neeg sib tw kub. Tab sis qhov kev yuav khoom tsis tau ua los ntawm kev xav tau nyiaj txiag ntau dhau. Muaj kev sim siv, piv txwv li, Windows NT, Solaris, TalOS (ua ke nrog IBM) thiab A/UX, tab sis tsis ua tiav.
Cov lus tshaj tawm rau lub Kaum Ob Hlis 20, 1996 ua rau sawv daws xav tsis thoob. Apple yuav NeXT rau $429 lab nyiaj ntsuab. Steve Jobs tau raug ntiav ua tus kws pab tswv yim thiab tau txais 1,5 lab Apple shares. Lub hom phiaj tseem ceeb ntawm qhov kev yuav khoom no yog siv NeXTSTEP ua lub hauv paus ntawm kev ua haujlwm yav tom ntej rau Macintosh computers.
Lub Peb Hlis 16, 1999 raug tso tawm Mac OS X Server 1.0 tseem hu ua Rhapsody. Zoo li Mac OS 8 nrog Platinum ntsiab. Tab sis sab hauv, lub kaw lus yog ua raws li kev sib xyaw ntawm OpenStep (NeXTSTEP), Unix Cheebtsam, Mac OS, thiab Mac OS X. Cov ntawv qhia zaub mov saum toj kawg nkaus ntawm lub vijtsam yog los ntawm Mac OS, tab sis kev tswj cov ntaub ntawv tau ua tiav hauv NeXTSTEP's Workspace Manager hloov. ntawm tus Finder. Tus neeg siv interface tseem siv Display PostScript rau zaub.
Thawj tus neeg siv beta version ntawm Mac OS X (codenamed Kodiak) tau tso tawm rau lub Tsib Hlis 10, 1999. Nws yog npaj rau cov neeg tsim khoom sau npe nkaus xwb. Thaum lub Cuaj Hlis 13, thawj pej xeem beta version ntawm Mac OS X tau tso tawm thiab muag rau $ 29,95.
Lub kaw lus tau coj ntau yam tshiab: kab hais kom ua, kev tiv thaiv kev nco, kev ua haujlwm ntau, ib txwm siv ntau lub processors, Quartz, dock, Aqua interface nrog cov duab ntxoov ntxoo thiab cov txheej txheem-theem PDF txhawb nqa. Txawm li cas los xij, Mac OS X v10.0 tsis muaj DVD playback thiab hlawv CD. Nws yuav tsum muaj G3 processor, 128 MB ntawm RAM thiab 1,5 GB ntawm qhov chaw hard disk dawb rau nruab. Backward compatibility kuj tau ua kom ntseeg tau ua tsaug rau qhov muaj peev xwm khiav OS 9 thiab cov kev pab cuam tsim los rau nws hauv qab txheej Classic.
Qhov kawg version ntawm Mac OS X 10.0 tau tso tawm thaum Lub Peb Hlis 24, 2001 thiab raug nqi $ 129. Txawm hais tias lub kaw lus tau raug hu ua Cheetah, nws tsis zoo hauv kev nrawm lossis ruaj khov. Yog li ntawd, thaum lub Cuaj Hlis 25, 2001, nws tau hloov pauv los ntawm kev hloov kho dawb rau Mac OS X 10.1 Puma.
Mac OS X yog dab tsi
Ib qho kev ua haujlwm raws li XNU hybrid kernel (hauv lus Askiv XNU's Tsis yog Unix), uas yog tsim los ntawm Mach 4.0 microkernel (sib txuas nrog cov khoom siv kho vajtse thiab saib xyuas kev tswj hwm kev nco, xov thiab cov txheej txheem, thiab lwm yam) thiab lub plhaub hauv daim ntawv. ntawm FreeBSD, uas nws sim ua tau tshaj. Lub hauv paus ua ke nrog rau lwm cov khoom ua rau Darwin system. Txawm hais tias BSD system siv hauv lub hauv paus, piv txwv li bash thiab vim yog siv, txawm hais tias hauv FreeBSD koj yuav pom csh thiab vi.1
