Izolo emva kwemini ibiyeyonyulwe yinkampani yaseCupertino ukumilisela Inguqulelo yesibini ye-beta yeMacOS ePhakamileyo yeSierra. Kule meko asinakuthetha ukuba ukuphuculwa okuphunyezwe kule nguqulo intsha yenkqubo yokusebenza kuyamangalisa ngokwenene, kodwa siyazi le nto ixesha elide ngenxa yamarhe ambalwa malunga neendaba okanye imisebenzi emitsha enokwenzeka ye-OS.
Kule meko, into esinayo etafileni yinguqulelo yesibini yabaphuhlisi be IMacOS ePhakamileyo yeSierra 10.13, kunye nenombolo yokwakha 17A291j. Kule nguqulo intsha ye-beta sifumana uphuculo kunye nokulungiswa kwe-bug xa kuthelekiswa nohlobo lokuqala olukhutshwe ekuqaleni kukaJuni, kodwa akukho nto ingako ichanekileyo kuba isebenza kakuhle kwinkqubo entsha.
Abaphuhlisi babhengeza kwisisombululo sesibini se-beta kwiingxaki ze-APFA, ukufuduka ukusuka ku-H.264 ukuya ku-H.265 nakwi-Metal 2. Olunye uphuculo kusebenze kweFayilevault phantsi kwenkqubo yefayile entsha ye-APFS, Ukuphuculwa kwesicelo seMiyalezo kunye ne-OpenCL, phakathi kolunye uphuculo kuhlobo lokuqala lwenkqubo entsha.
Kungcono ukuhlala kwezi nguqulelo ze-beta ukuba awungonjiniyela, kuba sinokuba nazo ezinye ingxaki yokungahambelani nezicelo okanye izixhobo zomsebenzi esizisebenzisa kwikhompyuter. Iinguqulelo ze-beta ezikhutshiweyo zihlala zizinzile kwaye kule meko ixesha elithe lafumaneka kwaye abanye sinokuthi le beta yesibini injalo kuba ayibonisi iimpazamo ezichaphazela ukusebenza ngokubanzi kweMac, kodwa akufuneki silibale ukuba ziinguqulelo ze-beta kwaye kungcono ukuba ulumke kunye nazo.
