I hope you have a modern Apple Watch or iPad, because otherwise watchOS 27 and iPadOS 27 won’t run on your device. Apple often drops support for older devices with its latest software updates, but this year it’s culling even more device generations than ever before.
Apple is dropping support for four generations of Apple Watch models in watchOS 27. The latest watchOS update will only be available on Apple Watch Series 10 devices and above, Apple Watch Ultra 2 and above, and Apple Watch SE 3. That means if you have a barely three-year-old Apple Watch Series 9 model then you’re out of luck. Likewise, if you purchased the original Apple Watch Ultra in 2022, there won’t be any watchOS 27 update waiting for you this fall.
It’s a surprise support cull for Apple Watch models, which consumers certainly don’t refresh as much as an iPhone. WatchOS 26, released a year ago, supported Apple Watch Series 6 and later, as well as Apple Watch SE (2nd generation) and later, and all Apple Watch Ultra models. This was the same list of devices as watchOS 11.
Over on the iPad side, iPadOS 27 cuts support for M1-powered models, removing the 3rd, 4th, and 5th generation iPad Air models from the compatibility list. iPad Pro owners will also need a 4th generation 12.9-inch model or above, or a 2nd generation 11-inch model and above. Apple is also cutting support for the 8th generation regular iPad models, so you’ll need a 9th generation model or above.
MacRumors points out that last year’s iPadOS 26 only dropped the 7th generation iPad models from the compatibility list last year, so Apple is significantly cutting the list of supported iPad devices this time around.
Both watchOS 27 and iPadOS 27 include an improved version of Siri, dubbed Siri AI. This might explain why watchOS 27 is only available on the watch models that support Apple Intelligence. But iPad models with M1 chips support Apple Intelligence, so it’s not clear why Apple has dropped support for these particular models in iPadOS 27.
Surprisingly, Apple is maintaining support for its iPhone 11 models with iOS 27 later this year. This means an iPhone from 2019 is supported by its latest OS updates, but an Apple Watch from 2023 isn’t. Make it make sense.
