Kwimizuzu nje embalwa edlulileyo u-Apple usungule entsha IMacOS Sierra yonjiniyela iBeta 10.12.4. Kwezi nguqulelo ze-beta, ezizizo iinguqulelo zokugqibela, zimbalwa utshintsho ezilindelweyo kwinqanaba lemisebenzi, kodwa kwinqanaba lolungiso lwempazamo kunye nokusombulula ingxaki. U-Apple uqhubele phambili kule veki ukumiliselwa kwale nguqulo ye-beta kuba ihlala ifika ngo-19: 18 emva kwemini (eSpain) kwaye kule meko iphehlelelwe ngo-00: 1 emva kwemini, into ebingazukubaluleka ukuba ibingu-beta XNUMX, kodwa okwangoku kungathetha ukuba bafuna ukukhupha ingxelo yokugqibela kungekudala.
Silindele abo baseCupertino ukuba bazise ingxelo yokugqibela kwaye akubonakali ngathi baya kuthatha ixesha elide ukuba sithathela ingqalelo inani leenguqulelo esele zikhutshiwe ukuza kuthi ga ngoku. Kule nguqulo, into ebonakalayo ngaphandle kwamathandabuzo yiNight Shift, into engayi kudlula kubasebenzisi abaninzi kodwa ilungile ngokubanzi kwinkqubo yokusebenza ngokusebenza ngakumbi.
Silinde ingxelo yoluntu ukuba ukuba yenzeka njengakwinguqulelo yamva nje ye-beta yabaphuhlisi, iya kufika ngokukhawuleza ukukhuphela, into ephakamisa ukuba iinguqulelo zifumana utshintsho oluncinci okanye iindaba ezimbalwa ezenziwayo kwi-beta ye-macOS. Ndiyathemba ukuba iWWDC ngoJuni yongeza ezinye izincedisi kwi-macOS, kodwa ngelixa ilixesha lokuhlala ulindile kunye nokwabelana ngezi nguqulelo ze-beta.
