Security readout for executives and security teams
Mac OS 9's idle lock could fail to protect an unattended session. A local person at the computer could use a logout cancellation path to return to the locked user's session. This is mainly a legacy, physical-access risk for any remaining Mac OS 9 systems. Exposure is likely limited to organizations still operating Mac OS 9 systems where unattended sessions rely on idle locking. Practical risk depends on physical or local console access, session privileges, and whether sensitive applications remain open. Treat as a legacy exposure issue, not a broad enterprise emergency. Prioritize if Mac OS 9 systems still handle sensitive data or sit in shared physical spaces. Otherwise, track as technical debt for retirement. Mitigation focus: Inventory any remaining Mac OS 9 systems and business owners.; Do not rely on idle lock as the only unattended-session control.; Restrict physical access to systems that cannot be retired..
