Futhi yilelo sonto eledlule kanye nelangaphambilini esiphelelwe yizinhlobo ze-beta, kepha kuleli sonto sesivele sinezinguqulo ezahlukahlukene ze-beta ezitholakalayo futhi phakathi kwazo kukhona ezingeke zalahleka, iMacOS High Sierra. Esimweni esinjalo sibhekene nenguqulo yesine ye-beta yohlelo lokusebenza lwe-Mac futhi abaningi babikezela inguqulo yokugcina ngesikhathi esithathe lezo zikaCupertino ukwethula le beta, kepha ekugcineni bekungekho.
Kulokhu ukwakhiwa kungu-17E170c futhi kuyo kulungiswa amaphutha ahlukile wenguqulo yangaphambilini futhi kwengezwe ukuthuthukiswa kokusebenza okujwayelekile. Futhi kulokhu kuthuthukiswa kufakwa ku-iCloud futhi okunye ukuvela kuvela kuhlelo lwe-iBooks. Ngamafuphi, izinguquko ezincane nokuthuthuka okuhlala kutholwa kahle ngabasebenzisi, yize kulokhu kusezandleni zonjiniyela.
Njengenjwayelo kulezi zinguqulo zentuthuko, kungcono ukuphuma endleleni yokugwema ukwehluleka okungenzeka ku-Mac yethu, ngakho-ke kungcono ukushiya ama-betas wonjiniyela futhi silinde izinhlobo zokugcina. Kunoma ikuphi, inguqulo esesidlangalaleni izovela ngesikhathi esifushane uma ingatholakali, kulezi zimo abasebenzisi banquma ukuthi bayayifaka noma cha.
I-Apple ibuyisela imishini ye-beta emuva kokusebenza ngemuva kwamasonto ambalwa ngaphandle kwezinguqulo ezintsha, kungabi ngokwentuthuko noma ohlelweni lwe-beta lomphakathi. Manje sesinayo le beta 4 etafuleni lonjiniyela, okuletha izindaba nokuthuthuka ohlelweni lokusebenza lwama-Mac ethu.
