Apple has sued the well-known leaker Jon Prosser for the alleged theft of trade secrets related to iOS 26. Prosser has been accused of tasking another man, Michael Ramacciotti, with secretly accessing an Apple employee’s development iPhone and using that information to report on Apple’s planned changes in the then-unannounced iOS 26.

Apple is suing leaker Jon Prosser and a codefendant for misappropriation of trade secrets related to YouTube videos from earlier this year that depicted mockups of iOS 26 (which was, at the time, expected to be called iOS 19).

YouTube influencer Jon Prosser allegedly violated Apple's intellectual property rights by illegally accessing and releasing trade secrets regarding the tech firm's iOS 26 operating system before its launch.
