OpenAI's Mac app now keeps a running record of what happens on the computer: the keys a person presses, where they click, which application they move to next. The feature is called Computer History, and its purpose is memory. ChatGPT watches a piece of work once, then offers to repeat it as an automation.
That record is written to the laptop as ordinary text files, with no encryption, so anything able to read files on that machine can read the log, including whatever an employee typed into a payroll system or a supplier contract.
Microsoft went through this in 2024 with Recall, which took a screenshot of the PC every few seconds. Researchers found the screenshot database stored in plain text, and the security researcher Kevin Beaumont pulled the whole thing off a machine in seconds. Microsoft withdrew the feature and brought it back with encryption and a fingerprint or face check. Tom's Hardware then tested the rebuilt version and found its sensitive-information filter still capturing credit card and Social Security numbers from the screen.
Nothing is recorded until a company administrator turns Computer History on. After that each employee decides individually, on their own laptop, whether ChatGPT should remember how they built Tuesday's report.
