Forensics on an Apple-issued MacBook that Chang Liu kept using after January let Apple argue destruction of evidence rather than definition of secrets, days before a judge weighs blocking OpenAI's hardware work.

A spoliation allegation is expensive in a different currency from the rest of this case. The cheapest defense OpenAI has filed is the motion to dismiss from earlier this month, arguing Apple failed to describe the trade secrets it claims or to show it owns protectable intellectual property [13], and that argument gets decided on the papers by a judge reading definitions. Conduct allegations get decided on credibility instead, which is why Apple's lawyers wrote that the laptop shows the company is "not conducting 'fishing expeditions'" but that its trade secrets are being used and evidence destroyed [7]. That sentence is drafted for a judge rationing discovery, not for a headline.
The ratios are the real argument here. Apple's complaint names two individuals, Liu and Chief Hardware Officer Tang Yew Tan [11], out of the more than 400 former Apple employees it says now work at OpenAI [12], which puts the named defendants at half of one percent of that population [1]. The single Apple-issued MacBook at the center of Monday's brief sat outside Apple's control from Liu's January departure to the July complaint, at least six months [2], and then took weeks of delay to produce [3]. Expedited fact-finding is Apple's request that the other 99.5 percent not be discovered at that rate; from the July complaint to the Oct. 1 hearing is roughly three months [3], which is quick for a trade-secret case and only useful if production accelerates.
OpenAI is now spending brief pages on something else entirely. Beyond the definitional argument, it is litigating Apple's own housekeeping: its Monday filing says any documents Liu opened were opened on behalf of Apple employees for Apple work purposes [8], and it asks the court to limit any injunction so workers are not restricted from changing jobs [9]. Apple attributes the post-departure access to an obscure authentication vulnerability it had not previously identified [10], while OpenAI says publicly that residual access "is a common issue with Apple which is caused by them failing to properly manage system access when people leave" [17]. Both sides accept that a departed engineer could still reach Apple files, and they are arguing about whose door was open.
The schematic matters less than the June message. A specific circuit schematic can be walled off, and Apple's own remedy list contemplates destroying proprietary materials [14], which a hardware team can survive with documentation. A finding that evidence was destroyed, though, colors every discovery dispute that follows, and no amount of engineering fixes that. Three ways it lands: a narrow order tied to identified schematic-derived work, which costs OpenAI paperwork; Apple's requested scope, barring hardware work based on Apple's technology [14], which imposes a provenance burden on the device program OpenAI is building with former Apple design chief Jony Ive [19]; or dismissal on the trade-secret definition first, in which case the forensics are never weighed [13]. The counter-thesis is the one OpenAI is already selling, that this is a single engineer assisting former colleagues [8] and industry-standard recruiting [18], and if the judge buys it a broad injunction becomes an odd fit for the facts.
The public record here is thin: the newest exhibits are redacted, and what has been seen are earlier text messages Liu punctuated with crying-laughing emojis [16]. Monetary damages are the part of Apple's ask that a check can settle [14]. The injunction is the part that spends OpenAI's calendar, and Oct. 1 is when that gets priced [15].
Ranked by verification strength, evidence, and original report placement.
Apple filed a court brief on Monday claiming OpenAI has been destroying evidence in the trade secrets dispute and that former Apple engineer Chang Liu incorporated a proprietary Apple circuit schematic into his work after joining OpenAI.
The filing was submitted in support of Apple's motion for expedited pretrial fact-finding and centers on a forensic analysis of an Apple-issued MacBook that Liu had been using since leaving Apple in January.
Apple said OpenAI provided the MacBook only after weeks of delay.
The forensic analysis found that Liu and others at OpenAI were aware of his continued unauthorized access to Apple's third-party cloud storage providers, according to Bloomberg.
Apple claims that after Liu learned he was under investigation he directed OpenAI colleague Yu-Ting Peng in June to destroy evidence, and that Peng agreed to do so.
The filing alleges Liu used a tool at OpenAI that shares a name with an internal Apple engineering application used for Apple development work.

Evidence-backed comparisons of source perspectives and observed adoption signals. Read the methodology
Which Builder, Operator, and Investor concerns the observed source mix emphasized—not a truth score.
Evidence, demonstrated adoption, hype gap, incentives, and confidence are assessed independently, each on its own current evidence. How these are measured.
Well-reported filings, sealed underneath
Everything specific in this story is Apple's lawyers characterizing documents no reader can see. Yahoo Finance and Mint independently quote the same passages and both trace the forensic findings to Bloomberg, with Mint adding TechCrunch — that is consistent reporting of one side's brief, not corroboration of what the laptop held. Mint alone notes the new material is redacted, which is the sentence that keeps the rest honest. The court-record facts here — filing dates, relief sought, the dismissal motion, the Oct. 1 hearing — are solid; the allegations they carry are untested.
Nothing shipped to measure
There is no deployment, release, benchmark or usage figure in play — this is a docket at an early stage. The nearest thing to a product fact is Mint's description of a doughnut-shaped, puck-sized smart speaker from the Ive collaboration, which is a roadmap detail, not something in anyone's hands. The 400-plus former Apple employees at OpenAI measures talent flow, not uptake of anything.
Overstated, and traceably so
The gap is not evenly spread. Yahoo Finance and Mint stay close to what the briefs say; Ventureburn escalates one filing into a Hollywood espionage drama, supplying wiped hard drives, deleted encrypted messages and shredded access logs that no other account attributes to any filing, plus an OpenAI denial of coordinated destruction phrased nowhere in the briefs as reported. Add the underlying redaction and the fact that Apple's spoliation theory has not been ruled on, and the accusation is currently louder than anything a reader can verify.
Two litigants, both filing for effect
Every substantive line here originates with a party that wants something from a judge within weeks. Apple's brief is written to secure expedited fact-finding and an injunction against a rival's hardware program; OpenAI's is written to get the case dismissed and to keep any order from touching employee mobility, which is why its rebuttal doubles as an argument about hiring. Even the leaks cut both ways — Apple's earlier filings surfaced Liu's emoji-punctuated texts, OpenAI has released message excerpts of its own. Ventureburn's framing carries a separate commercial tint, threaded with promos for unrelated funding rounds.
Confident on the docket, cautious on the conduct
We would stand behind the procedural spine of this story — the two Monday briefs, the laptop's late production, the relief Apple wants, the Oct. 1 hearing — because two careful accounts agree and it is court record. We hold the conduct allegations looser: they are one party's account of sealed material, filtered through wire reporting, and the third account in our coverage misstates a basic sequence. Nothing here should be read as a finding.
