John Carmack is not a fan of Mac. We now have that on the record, in court.

ZeniMax Media and Oculus VR are involved in a contentious court case over Carmack's contracts with ZeniMax prior to his departure in 2014 to become Chief Technology officer at Oculus, which has since been purchased by Facebook. The case centers on what Carmack knew, what he shared with Oculus chief Palmer Luckey, and what information was proprietary to ZeniMax in relation to ZeniMax's budding VR program. The company has even gone so far as top allege destruction of evidence by Oculus.

While on the stand last week (via UploadVR), Carmack was asked by Zenimax attorney Anthony Sammi if he knew about private hotel meetings between Oculus co-founders Nate Mitchell and Luckey, to which Carmack replied that he did not. "They were private," he said. When asked about a MacBook that was in evidence and why it had not been wiped, Carmack answered that "I am not a Mac user unless under duress."

The case hinges on how much information Oculus had on its own, with Carmack repeatedly stating that Oculus had an entire system, while ZeniMax contends it only had "simple lenses."

ZeniMax provided a statement to Shacknews about the ongoing proceedings: "With the start of the trial of our case in Federal District Court in Dallas against Defendants Facebook, Oculus and its management, ZeniMax and id Software welcome the opportunity to present substantial evidence of the Defendants' misappropriation of our Virtual Reality (VR) intellectual property. That evidence includes the theft of trade secrets and highly confidential information, including computer code. ZeniMax will also present evidence of the Defendants' intentional destruction of evidence to cover up their wrongdoing. ZeniMax and id Software are the visionary developers of breakthrough VR technology, and look forward to the vindication of our claims."
