The year 2040 triggers a date-related software bug in Apple's classic Hierarchical File System (HFS).
HFS and the Date & Time control panel from Mac OS 9.x can manage dates up to February 6, 2040, after which the clock will cycle back to January 1904.[1] Apple has since been migrating modern macOS users to its APFS file system, which does not have this limitation.
