Isla sidaas ayaa ku dhacday betas-ka iOS 10.3, watchOS 3.2 iyo tvOS 10.2. Laakiin inkasta oo tiro badan oo betas ah oo la sii daayay ka hor nooca ugu dambeeya, waxaa jira horeyba isticmaaleyaasha qaarkood ee ka warbixinaya dhibaatooyinka cusboonaysiintaan ugu dambeysay.
Muddo seddex maalmood ah, horumariyayaashu waxay horeyba u haysteen suurtagalnimada inay soo dejiyaan beta-kii ugu horreeyay ee macOS 10.12.5, laakiin dhowr saacadood ka hor, Apple ayaa sidoo kale soo saartay beta-ka dadweynaha ee isla beta-kii ugu horreeyay.

Maskaxda ku hay in Apple ay durbaba bilowday inay ka shaqeyso nooca soo socda ee macOS, oo ah nooca ay tahay inuu noo keeno warar cusub, sidaa darteed Apple kuma dari doono shaqooyin cusub nidaamkan horey u soo shaqeeyay ee ruug cadaaga ahaa.
Mid ka mid ah sheekooyinka soo jiitay dareenka ugu badan ee cusbooneysiinta 10.12.4 waa habka Shift Night, oo ah qaab loogu talagalay dhammaan kuwa isticmaala ee aan dooneynin inay yeeshaan dhibaatooyin hurdo adoo adeegsanaya Mac-gaaga xaaladaha iftiinka yar.
