Official response regarding GPT-5.6-SOL deleting Mac files is here: The investigation shows that this file deletion issue mainly occurs in specific development configurations. When users enable 'Full access mode' and run Codex without activating Sandboxing protections or the Auto review mechanism, the model encounters a logical error while attempting to override the HOME environment variable to define a temporary directory. Instead of correctly pointing to the temporary path, the model mistakenly executes the command to delete the entire HOME root directory of the user. To mitigate this risk, the tech team is taking urgent remedial actions. These include updating developer prompt information, guiding users toward safer permission management modes, and adding mandatory harness safeguards at the system level.
