YouTuber Jon Prosser is set to be deposed in a lawsuit filed against him by Apple.
After a default judgment against him for non-responsiveness, YouTuber Jon Prosser is now facing a trial and jury trial over his iOS 26 leaks.
In July 2025, after revealing design details of what was then known as iOS 19, leaker Jon Prosser was sued by Apple for allegedly misappropriating trade secrets. Things don’t seem to have gone well so far, though he continues to post videos about Apple rumors.
Prosser was served with documents and subpoenas. He will have to provide sworn, out-of-court testimony to allow Apple to determine the extent of confidential information Prosser obtained and shared.
Ace 9 to 5 March notes that while the decision is in Apple’s favor, the iPhone maker is now seeking an injunction against Prosser so that he can no longer “disclose Apple’s confidential, proprietary and trade secret information to third parties without its written consent.”
Apple is also seeking damages in an amount to be determined during the trial, along with attorneys’ fees.
The company’s demands are outlined in a case status update filed in February 2026, and the requested injunction would also apply to co-defendant Michael Ramacciotti.
The Apple v. Prosser lawsuit so far
In March 2025, Prosser showed off what was then called iOS 19’s alleged iMessage and Camera interface.

Later, in April 2025, he published what he said were the design details of the then-unannounced iOS 26. To protect his source, Prosser did so using artificial recreations and renders, rather than images of the operating system itself.
Despite Prosser’s obfuscation, Apple managed to identify the source of the leak relatively quickly.
After doing so, he sued iPhone maker Jon Prosser and his alleged co-conspirator Michael Ramacciotti, alleging the two misappropriated trade secrets and violated the Computer Fraud and Abuse Act.
According to Apple, Ramacciotti secretly gained access to iPhone development that belonged to his friend Ethan Lipnik, an Apple employee at the time.
Without Lipnik’s knowledge, Ramacciotti allegedly obtained the password to the development device, later showing Jon Prosser its operating system via FaceTime. Lipnik was eventually fired, while Prosser and Ramacciotti faced legal action from Apple.
As the lawsuit against them continued, Apple claimed in October 2025 that Prosser had missed a short deadline. Prosser denied this, saying at the time that he had “actively communicated with Apple since the beginning of this case.”
It is understood that Prosser and Apple are in contact and are currently still in a limited discovery phase, despite the default ruling in Apple’s favor. The date of Prosser’s deposition has not yet been announced.
As for Michael Ramacciotti, he provided computers and archives to Apple for forensic review. Apple filed with Ramacciotti on December 17, 2025.
While the lawsuit is still ongoing, things aren’t looking good for Jon Prosser. However, the second case update is scheduled for April 13, 2026.
