Ukuthintela Abasebenzisi abangagunyaziswanga kwiBhooting Up Mac yakho
IiMac zineenkqubo ezikhuselekileyo ezakhelwe kwiinkqubo zokhuseleko. Bavame ukuba nemiba embalwa kunye ne-malware kunye neentsholongwane kunamanye amaqonga e-computer. Kodwa oko akuthethi bahlala bekhuselekile ngokupheleleyo.
Oku kuyinyani ngokukodwa ukuba umntu unokufikelela kwimpilo yakho kwi-Mac, into eyenzekayo xa i-Mac ibiwe okanye isetyenziswe kwindawo evumela ukufikelela lula. Enyanisweni, ukugqithisa ukhuseleko olusisiseko olunikezwa inkqubo ye-akhawunti yomsebenzisi we-OS X yi-cakewalk. Akufuneki naziphi izakhono ezizodwa, nje ixesha elithile kunye nokufikelela ngokomzimba.
Mhlawumbi usuvele uthathe amanyathelo okuqapha, njengokuqinisekisa ukuba i-akhawunti yakho yomsebenzisi we-Mac yonke ineephasiwedi ezinzima ukuqiqa "iphasiwedi" okanye "12345678." (Ukuzalwa kunye negama lakho lesilwanyana akukhethi kakuhle, mhlawumbi.)
Ungasebenzisa kwakhona i- disk encryption system , efana neFayileVault 2 , ukukhusela idatha yakho. I-Mac yakho iyakwazi ukufikelela, nangona idatha yakho yomsebenzisi mhlawumbi ikhuselekile ngokukhethiweyo.
Kodwa akukho nto iphosakeleyo ngokufaka olunye uhla lokhuseleko kwi-Mac yakho: iphasiwedi ye-firmware. Le milinganiselo elula inokuthintela umntu ukuba asebenzise enye yeenkcenkceshelo zekhibhodi ezininzi ezitshintsha ukulandelelana kwebhodi kwaye unokunyanzela iMac yakho ukuba iqalise ukusuka kwelinye idrayivu, ngaloo ndlela wenze lula ukufikelela kwedatha yakho ye-Mac. Ukusebenzisa amancinci ekhibhodi, umsebenzisi ongagunyazisiyo unokuqalisa kwakhona kwimodi yomsebenzisi oyedwa kwaye wakhe i-akhawunti yomlawuli entsha , okanye uphinde usethe iphasiwedi yakho yomlawuli . Zonke ezi zixhobo zingashiya idatha yakho ebalulekileyo yokuvuna yokufikelela.
Kodwa akukho zikhetho ezikhethiweyo zekhibhodi ziya kusebenza xa inkqubo yokuqalisa ibandakanya iphasiwedi. Ukuba umsebenzisi akakwazi ukuba iphasiwedi, iinqamfayile zebhobhobhodi ayinalutho.
Ukusebenzisa iphasiwedi ye-Firmware yokuLawula ukufikelela kwi-Boot kwi-OS X
I-Mac isekude isekela iphasiwedi ye-firmware, ekufuneka ifakwe xa iMac inikwe amandla. Kubizwa ngokuba yiphasiwedi ye-firmware kuba igcinwe kwimemori engavumelekanga kwi-motherboard ye-Mac. Ngethuba lokuqalisa, i-firmware ye-EFI ihlola ukuqinisekisa ukuba ngaba kukho utshintsho oluya kulandelelwano oluqhelekileyo lwe-boot lucelwa, njengokuqala kwimodi yomsebenzisi omnye okanye kwi-drive ehlukile. Ukuba kunjalo, iphasiwedi ye-firmware iyacelwa kwaye ihlolwe ingqalelo kwi-version egcinwe. Ukuba ngaba ngumdlalo, inkqubo yokuqalisa ibhola iqhubeka; ukuba kungenjalo, inkqubo yokuqalisa ibama kwaye ilinde iphasiwedi echanekileyo. Ngenxa yokuba konke oku kwenzeka ngaphambi kokuba i-OS X ilayishwe ngokugcwele, izikhetho eziqhelekileyo zokuqala zokuqala azifumaneki, ngoko ke ukufikelela kwi-Mac akufumaneki, nokuba kunjalo.
Kwixesha elidlulileyo, iphasiwedi ye-firmware yayilula lula ukuhamba. Susa i-RAM, kwaye iphasiwedi yachithwa ngokuzenzekelayo; ayikho inkqubo efanelekileyo. Ngo-2010 nakwi-Macs kamva, i-firmware ye-EFI ayisayi kuphinda ivuselele iphasiwedi ye-firmware xa utshintsho olwenziweyo lwenziwa kwinkqubo. Oku kwenza iphasiwedi ye-firmware ibe ngumlinganiselo wokhuseleko olungcono kubasebenzisi abaninzi be-Mac.
Iphasiwedi yeeMxwayiso
Ngaphambi kokuba unike amandla inkcazelo yephasiwedi ye-firmware, amagama ambalwa okulumkisa. Ukulibala iphasiwedi ye-firmware ingakhokelela kwihlabathi elibuhlungu ngenxa yokuba akukho ndlela elula yokuyibuyisela kwakhona.
Ukunika amandla iphasiwedi ye-firmware ingenza kwakhona ukusebenzisa i-Mac yakho nzima. Uya kufuneka ukuba ufake iphasiwedi nayiphi na ixesha xa unamandla kwi-Mac usebenzisa iifutshane zekhibhodi (umzekelo, ukuqala kwimodi yomsebenzisi omnye) okanye zama ukukhupha kwi-drive ngaphandle kwesiqalo sakho sokuqalisa.
Iphasiwedi ye-firmware ayiyi kukunqanda (okanye nayiphi na enye) ukusuka ekuqhubeni ngqo kwi-drive yakho yokuqalisa. (Ukuba i-Mac yakho idinga iphasiwedi yomsebenzisi ukungena ngemvume, le phaswedi iya kusadingeka.) Iphasiwedi ye-firmware iyasebenza kuphela xa umntu ezama ukuphepha inkqubo eqhutywayo yokuqalisa.
Iphasiwedi ye-firmware ingaba yinto enhle kwi-Macs ephathekayo ekwazi ukulahleka okanye eyebiwe, kodwa ngokubalulekileyo ayibalulekanga kwi-desktop Macs engashiyi ekhaya, okanye ikhona kwiofisi encinci apho bonke abasebenzisi baziwayo. Ngokuqinisekileyo, kufuneka usebenzise indlela yakho yokukhetha ukuba unqwenela ukuvula iphasiwedi ye-firmware.
Ukunika i-Password yakho ye-Mac & # 39;
I-Apple inikezela ngetyenziso lokunika ithuba lokukhetha iphasiwedi ye-firmware. Ukusetyenziswa akuyona inxalenye ye-OS X; mhlawumbi kwi-DVD yakho yokufaka (i- OS X Snow Leopard nangaphambili) okanye kwiSahlulo se-HD sokubuyisela ( OS X Lion kunye nangemva koko). Ukufikelela kwi-password ye-firmware, kufuneka uqalise kwakhona iMac yakho kwi-DVD yokufaka okanye i-partition ye-HD.
Boot usebenzisa i-DVD
- Ukuba uqhuba i-OS X 10.6 (i- Snow Leopard ) okanye ngaphambili, faka i-DVD yokufaka uze uqale kabusha iMac yakho ngelixa ubambe iqhosha "c".
- I-installer ye-OS X iya kuqala. Ungaxhalabi; asiyi kufaka nayiphi na into, sisebenzise esinye sezixhobo zesevisi.
- Khetha ulwimi lwakho, uze uklikha iqhosha lokuqhubeka okanye utolo.
- Yiya kwi- Setting ye-Firmware yegama lephasiwedi , ngezantsi.
I-Boot usebenzisa i-HD yokubuyisela
- Ukuba usebenzisa i-OS X 10.7 (iNgonyama) okanye kamva, unokuqalisa kwiSahlulo se-HD sokubuyisela.
- Qala kabusha i-Mac yakho ngelixa ugcina phantsi iqhosha lomyalelo +. Hlala ubamba iifowuni zombini kude kuvele ideskithophu ye-HD yokubuyisela.
- Yiya kwi- Setting ye-Firmware yegama lephasiwedi , ngezantsi.
Ukubeka iphasiwedi yeFirmware
- Ukusuka kwimenyu yeeUtilities, khetha u-Firmware Password Utility.
- IWindows Window Utility window iya kuvula, ukukwazisa ukuba ukuguqula iphasiwedi ye-firmware izakukhusela iMac yakho ukuba iqale ukusuka kwi-drive, CD, okanye i-DVD ngaphandle kwephasiwedi.
- Chofoza ukuvula iqhosha le-Password yeFirmware.
- Ifayile ehlayo iya kukucela ukuba unikezele iphasiwedi, kunye nokuqinisekisa iphasiwedi ngokungena kwesibini. Faka iphasiwedi. Gcina ukhumbule ukuba akukho ndlela yokufumana iphasiwedi elahlekileyo iphasiwedi, ngoko qiniseka ukuba into oyakuyikhumbula. Ukuze iphasiwedi eneqinileyo, ndincoma kubandakanywa zombini iileta kunye namanani.
- Cofa ku-Set Set Password.
- Iwindow ye-Password yeWtility Window iya kutshintsha ukutsho ukuba ukukhuselwa kwephasiwedi kunikwe amandla. Cofa ukukhupha iqhosha laseFirmware Password Utility.
- Yeka Mac OS X IiNkonzo.
- Qala kabusha iMac yakho.
Ngoku ungasebenzisa iMic yakho ngokuqhelekileyo. Awuyi kubona nayiphi na impazamo ekusebenziseni i-Mac yakho ngaphandle kokuba uzame ukuqala iMac yakho usebenzisa i-shortcut keyboard.
Ukuvavanya iphasiwedi ye-firmware, gcina inketho yokukhetha ngexesha lokuqalisa. Kufuneka ucelwe ukuba unikezele iphasiwedi ye-firmware.
Ukukhubaza iphasiwedi yeFirmware
Ukuguqula inketho yephasiwedi ye-firmware, landela imiyalelo ngasentla, kodwa ngeli xesha, nqakraza iqhosha le-Turn Off Firmware Password. Uyacelwa ukuba unikezele iphasiwedi ye-firmware. Emva kokuqinisekiswa, iphasiwedi ye-firmware iya kukhutshazwa.
