build number is 25F5053d

others:

macOS 15.7.6 RC 2 (24G711)
macOS 14.8.6 RC 2 (23J511)
iOS 26.5 beta 2 (23F5054d) - via ipsw
iOS 26.5 beta 2 (23F5054h) - via ota
iPadOS 26.5 beta 2 (23F5054d) - via ipsw
iPadOS 26.5 beta 2 (23F5054h) - via ota
watchOS 26.5 beta 2 (23T5553h)
visionOS 26.5 beta 2 (23O5453d)
tvOS 26.5 beta 2 (23L5455c)
audioOS 26.5 beta 2 (23L5455c)

there seem to be 2 builds for ios and ipados depending how you install it. ipsw's have d's and ota install has h in the build

btw it seems ipsw's for the ios and ipados d builds have difficuties installing:

it really means they should pull those d ipsw's and make new h ipsw's to replace them. dunno if that has happened yet or even if it will ever happen.

there is also a mythical creature called watchOS 26.5 beta 2 (23T5553d) even though there is no ipsw for watchos!
