New iPhone 18 Pro Models Will Have Day One Update

Customers receiving an iPhone 18 Pro, ‌iPhone 18 Pro‌ Max, an Apple Watch Series 12, or an Apple Watch Ultra 4 tomorrow will need to install a software update right away.

iOS 27 Feature Dark
The ‌iPhone 18 Pro‌ and ‌iPhone 18 Pro‌ Max ship with iOS 27 variants with a 24A427 or 24A8428 version number. The launch version of ‌iOS 27‌ is version 24A437, so if you're getting an ‌iPhone 18 Pro‌, expect a software update during the setup process.

The Apple Watch Series 12 and the ‌Apple Watch Ultra 4‌ have watchOS 27 with a version number of 24R359, but the launch version of ‌watchOS 27‌ is 24R364.

We're also expecting the AirPods 5 to have a day one firmware update, though that will happen over the air. Apple recently released 9A350 AirPods firmware to add support for ‌iOS 27‌ features.

All of the new products are set to launch on Friday, September 18.

Whatever happened to the Apple Stores having these toolbox things to update the software without opening the box? Did that fall through?

1000% agree I have to assist 9 less technical savvy people tomorrow i'm super excited.

I hope you can skip and update after the setup I may test with the first person.
Literally all you have to do in setup is click next & wait.

Who are these people?

I can answer this one. Apple employees are only required to update iPhones when there is a new version, not a new build number of the same main version. They could actually update them, there is nothing preventing them from doing it but there is too much work on the launch day to update each and every iPhone just because.

I wish Apple gave us the devices FULLY UPDATED AND READY TO GO. Having to update first increases setup time substantially!

This happens every single year, nothing new was expecting this post
Yeah, weird article. How could there NOT be a day 1 update required when setting up the phone? It's not like the iOS 27 final release version was available when all these phones were originally manufactured. Of course there's an update required during setup.
