If you’re someone who follows news about leaked Apple products, there’s a good chance that the name Jon Prosser comes to mind. Prosser has been instrumental in leaking upcoming Apple products ahead of their release. Now, he finds himself in the spotlight again, but this time because Jon Prosser is being sued by Apple over the iOS 26 leaks.
Jon Prosser sued by Apple
At WWDC 2025, Apple took the wraps off iOS 26. This is the next major iOS update and offers the biggest design overhaul we’ve seen since iOS 7. However, there were a ton of leaks leading up to the announcement. One of those leaks came from Prosser, who shared a mockup video giving us a taste of what’s to come.
For the most part, Prosser’s mockup was pretty close to the real thing. It showed off the new Liquid Glass design language that Apple adopted for the update. This visual overhaul shows off a more transparent and translucent UI that looks like frosted glass. Unfortunately, maybe the mockup was too close to the real thing, which landed Prosser in hot water as Apple is now suing the leakster because of it.
Now, Jon Prosser and Michael Ramacciotti are being sued by Apple for alleged misappropriation of trade secrets. According to Apple’s timeline of events, Apple employee Ethan Lipnik had a development iPhone in his possession. The company alleges that Prosser and Ramacciotti plotted to access the phone to gain an early peek into iOS 26.
It also seems that Ramacciotti made a FaceTime call to Prosser using the phone, which Prosser recorded using screen capture tools. He then used information from the video to recreate renders of iOS 26. Unfortunately for Lipnik, he was fired from Apple for failure to follow Apple’s policies to protect development and released devices. He had also failed to disclose the breach to Apple after learning about it.
Prosser’s response
Prosser has since responded to the lawsuit. In a post he made on his X account , he said, “For the record: This is not how the situation played out on my end. Luckily have receipts for that.” He also said, “I did not ‘plot’ to access anyone’s phone. I did not have any passwords. I was unaware of how the information was obtained. Looking forward to speaking with Apple on this.”
We also reached out to Prosser for additional comment, to which he replied by saying, “I would love to explain how things happened on my end. But for obvious reasons, I feel like I should hold from saying anything before I get to give the court my side.”
