Sii deynta macruufka 11 waa bilowga dhammaadka codsiyada aan wali loo casriyeynin 64-bit processor-ka maanta. Apple waxay ku adkeysaneysay beeshan dhowr sano si codsiyada ay ula qabsadaan noocan processor-ka ah, laakiin waxay umuuqataa in kaliya aysan dooneynin barnaamijyada iOS inay la jaan qaadaan 64-bit processor-ka, laakiin hada iyaga ayaa loo jeedaa nidaamka deegaanka ee macOS. Ragga ka socda Cupertino waxay bilaabeen inay e-mayl u diraan kuwa soo hagaajiya arjiga iyaga oo xusuusinaya baahida loo qabo u cusbooneysii codsiyadaada processor-yada 64-bit, illaa iyo inta ay rabaan inay ku jiraan Mac App Store.
Laakiin marka lagu daro Apple waxay ku daabacday baloog loogu talagalay horumariyeyaasha waqtiyada la qabsiga ee codsiyada. Bishii Janaayo 2018, dhammaan codsiyada cusub ee loo gudbiyey Mac App Store waxay u baahan doonaan inay taageero siiyaan 64-bit processor. Laga soo bilaabo Juun 2018, dhammaan codsiyada loo gudbiyey Mac App Store si loo cusbooneysiiyo waxay sidoo kale u baahan doonaan inay noqdaan 64-bit processor-karti leh. Isla qoraalkaas, Apple waxay kugula talineysaa horumariyeyaasha bixiya barnaamijyadooda ka baxsan App Store, in la qabsadaan si ay u sii wadi karaan inay ku shaqeeyaan qaybta soo socota ee macOS.
Sida laga soo xigtay Apple, High Sierra waxay noqon doontaa nooca ugu dambeeya ee u oggolaan doona socodsiinta codsiyada 32-bit ah iyada oo aan wax dhibaato ah la qabin, Laakiin imaatinka nooca soo socda ee macOS, Apple wax taageero ah kuma siin doono codsigan noocan oo kale ah, sidaa darteed hawlgalkeedu wuxuu bilaabi doonaa inuusan xasilloonayn sida uu maanta yahay. Ragga ka socda Cupertino ayaa la sii daayay shalay, ka dib bilooyin badan oo sugitaan ah, beta-kii ugu horreeyay ee macOS High Sierra, nooca xiga ee nidaamka hawlgalka ee kombuyuutarrada Apple Mac.
