Abo baseCupertino baqalise i IMacOS Sierra 4 beta 10.12.5 yabaphuhlisi ngeempawu ezintsha malunga nokhuseleko kunye nozinzo lwenkqubo, kunye neebhugi zoguqulelo lwangaphambili nazo zilungisiwe. Kule meko, njengeenguqulelo zangaphambili ze-macOS Sierra 10.12.5, ayibonakali inalo naluphi na utshintsho oluphawulekayo ekusebenzeni kwenkqubo; ezi zilungiso kunye nezisombululo kwiibhugi zenguqulo yangaphambili. I-Apple iya kulungiselela inguqulelo entsha ye-WWDC ngoJuni kwaye asikholelwa ukuba utshintsho olubalulekileyo ngokwemigaqo yemisebenzi emitsha luya kongezwa kude kube ngulo mhla.
Okomzuzwana Inguqulelo ye-beta ayikakhululwa kubasebenzisi abangaphakathi kwenkqubo ye-beta yoluntu, kodwa asithandabuzi ukuba kwiiyure ezimbalwa ezizayo okanye ngomso izakuvela ukuze ikhutshelwe. I-Apple icacile ukuba ezi beta zilungisa iibhugi kwaye zingafaki iimpawu ezintsha, kodwa kuyinyani ukuba iibhugi ezincinci, ukuphuculwa kokhuseleko okanye ukusombulula ingxaki zincinci kule nguqulo, engenamahluko amaninzi kakhulu ukusuka ngaphambili.
Kuya kufuneka sikhumbule ukuba olu luguqulelo lwe-beta kwaye kungcono ukuhlala ngaphandle kwayo ukuba awungomphuhlisi, kuba sinokuba nayo. ingxaki yokungahambelani nezicelo, izixhobo zokusebenza esizisebenzisa kwikhompyuter okanye iimpazamo enokulimaza amava omsebenzisi kwi-Mac. Iinguqulelo ze-beta ezikhutshiweyo zihlala zizinzile kwaye zineempazamo ezimbalwa ezichaphazela ukusebenza kwesixhobo, kodwa asimele silibale ukuba ziinguqulelo ze-beta kwaye kungcono ukuba silumke kunye nabo.
