tl;dr: Apple filed new evidence in its trade secret lawsuit against OpenAI and former engineer Chang Liu, claiming forensic analysis of Liu's MacBook shows he downloaded a confidential Apple circuit schematic and used it in LTspice simulations at OpenAI, allegedly feeding it to an AI agent. Apple also alleges Liu instructed an OpenAI colleague to destroy evidence after learning of Apple's internal investigation. Apple is using the findings to push for expedited discovery and access to a related Mac mini that synced to the laptop via iCloud.
