The latest operating systems from Apple will leave some of its older devices in the dust as is tradition. In other words, all the phones Apple has released since 2017 will be able to run iOS 16 when it arrives in the fall. Apple will not be able to upgrade iPhone 6S, iPhone 7, and iPhone SE  users to iOS 16.

Apple will discontinue supporting iPad Mini 4 and iPad Air 2 with iPadOS 16. It's safe to say both devices are getting on in years since the Mini 4 was released in 2015 and the Air 2 was released in 2014. In fact, Apple has continued to support them all the way up to iPadOS 15. It's a testament to their staying power.

The Apple Watch Series 4 and later is required to run watchOS 9. Apple Watch Series 3 users could install watchOS 7 and watchOS 8, but some features were unavailable. When it comes to macOS Ventura, things get a little more complicated. 

Compared to macOS Monterey, the latter is compatible with a late 2015 or later iMac, a 2017 or later iMac Pro, an early 2015 or later MacBook Air, an early 2015 or later MacBook Pro, a 2013 or later Mac Pro, a late 2015 or later Mac mini, and an early 2016 or later MacBook.

Although all of the iPad Air 2 and 2013 Mac Pro models it is no longer supporting were all released at least five years ago, it's always sad to see them go.

It is likely that Apple will hope those who continue to use older models will upgrade soon, even though they will still be able to use them.
