WWDC early this morning is a pleasant event for some people, because iOS 12's list of support models is exactly the same as iOS 11, which means that their iPhone will continue for another year. But some people may not be very happy because watchOS 5 will not support the early generation of Apple Watch.
Let's take a look at the iOS support list. If the device on your hand can run iOS 11 now, it can be upgraded to iOS 12, iPhone is first supported by iPhone 5S and SE, iPad supports five generation iPad and iPad Mini 2 at the earliest, and iPod supports the six generation.
And macOS Mojave eliminated a number of old models, and the 2015 and later MacBook, 2012 and later MacBook Air, 2012 and later MacBook Pro, 2012 and later Mac mini, 2012 and later iMac and 2017 iMac Pro. The tower cabinets in 2010 and 2012 are also supported because they are compatible with Metal.
Generally speaking, as long as your Mac is not antique before 2012, you can try macOS Mojave.
TvOS 12 can be used for the fourth generation of Apple TV and later equipment. This Apple TV was released in 2015.
And the first generation of Apple Watch users should be the worst, the product was sold in 2015, but watchOS 5 no longer supports it, which means that even if you spent 17000 dollars (about 108885 yuan) in 2015 (about 108885 yuan) sold a gold version of Apple Watch Edition, you have to face the crisis of being eliminated.
Don't feel that not many people buy this watch, Apple has never launched a golden version of Apple Watch after the first generation, and they used ceramic version of the fuselage to replace the previous gold fuselage, so the American stars, including Beyonce and others, are the users of the first Apple Watch.
