Iindaba ezimbi ze-Intel kunye ne-Apple, engumsebenzisi wezi chips. Ngokukodwa ezo Macs phambi kokudityaniswa kweT1 kunye neT2 chips, oko kukuthi, abo bangaphambi kwe-2016. Ubuthathaka obutsha bufunyenwe kubo, kwaye ingxaki enkulu kukuba ayinakusombululwa, ngoko ke impazamo yokhuseleko ikhona ngokuqhubekayo.
Ubuthathaka obutsha ivumela ukwaphula ikhonkco lokuthembela kwenkitha yeeprosesa kunye neechipsets ezenziwe yi-Intel, ukushiya iingcango zivuliwe ekuphelisweni kwe-hardware kunye/okanye i-DRM yoguqulelo oluntsonkothileyo kunye nokhuselo lokuchonga.
Oku buthathaka kwiichips ze-Intel kuchaphazela ngokupheleleyo inkqubo yeFayileVault yeeMacs
Ukuba sesichengeni kugxile kwinto ebizwa ngokuba yi-CSME (Injini yoLawulo loKhuseleko oluGuquliweyo). Into enoxanduva lokukhusela i-firmware yezo khompyutha kunye neprosesa ye-Intel, kunye ne-Macs ngaphambi kwe-2016, ibe nazo. Ngaphaya koko, esi siphene sokhuseleko sinokuchaphazela ngokuthe ngqo inkqubo yokhuseleko. Uguqulelo oluntsonkothileyo lweFayileVault ukusuka Apple, ewe, ezo Macs ukuba T1 okanye T2 chi abachatshazelwa ngolu kusilela.
Ukuba sesichengeni kunemvelaphi ephindiweyo, kuba kukho ibug engasonjululwanga ngesoftware (hard-coded) kunye nempazamo kwi-CSME firmware ngokwayo, eqala inkqubo yoqinisekiso. Kunjalo ngoba, oku akunakulungiswa kwaye kunzulu ngokwaneleyo ukuyeka ukusebenzisa ezi chips kwiiMacs.
Enyanisweni, sele iqinisekisiwe ubukho beMac yexesha elizayo enetshiphu ye-ARM. Kusengqiqweni, kuba i-Intel ibangela iingxaki ezininzi. Ezinye zazo ziye zasonjululwa, nangona kunjalo oku kufunyenwe mva nje kuthetha ukuba ukuzithemba kule nkampani kunye nemilinganiselo yayo yokhuseleko ilahlekile.
I-Intel iqinisekisile ukuba ngohlaziyo oluhambelanayo lwe-CSME kunye ne-BIOS, baya kunciphisa amathuba okubandezeleka kuhlaselo lwasekhaya kwaye bazame ukuvimba zonke ii-vectors zokuxhaphaza ezinokubakho. Noko ke, balumkisa ngelithi ukuba kunokwenzeka ukuhlaselwa ngokwasemzimbeni kuya kuluphelisa unqabiseko.
