Hello, why hasn't iOS 26 beta arrived on my iPhone 13 Pro Max yet?

Because the official release will not be available until sometime this fall.

You might be thinking about the test or beta versions. That is only for users with a very high pain tolerance.

The Public Beta will be available soon, but you don't want to mess with any Beta version......unless......you will be using a spare phone. Bugs, bugs, bugs. Things....cannot say which....that work fine now on your phone won't on the Beta......guaranteed.

iOS 26 Beta is currently only for Apple Developers. The Public Beta should be released next month. Then Public Release should be in the Fall.

iOS 26 has not yet been released. Visit developer.apple.com for details.

It’s normal for BETA versions not to show up unless you register in the Developer App

And a tip: don’t install the BETA version

Great tip.

If you aren’t enrolled in the developer program then you cant install it yet but if you are enrolled in the beta program then you will have to wait till july 14 until the public beta is out :)
