How to check your Mac’s manufacture date in macOS 27

MacRumors says macOS 27 Golden Gate restores access to manufacture-date information that effectively disappeared when Apple randomized its serial numbers a few years ago.

TLDR

macOS 27 Golden Gate adds a “Date of Manufacture” field under System Settings → General → About → Regulatory Certification, MacRumors reports. The field makes hardware-age information visible again after Apple’s randomized serial numbers removed the old decoding shortcut. It may reflect the logic board rather than the original computer after a repair, so buyers should treat it as a component clue, not an infallible purchase-history record.

Apple has added a direct way to view a Mac’s manufacture date in macOS 27 Golden Gate, replacing information that became harder to infer after the company began randomizing serial numbers.

MacRumors’ guide directs users to System Settings, then General and About. Clicking “Regulatory Certification” beneath the System Report button opens a certificate with a new “Date of Manufacture” field at the bottom.

What the date can tell you

The field offers a quick check when identifying the age of a machine, comparing it with a purchase record or evaluating a used Mac. Older serial-number formats encoded manufacturing information, but Apple’s randomized serial numbers removed that dependable shortcut.

The date still needs context. A Mac whose logic board was replaced may show the replacement board’s manufacturing date rather than the date when the original computer left the factory. That makes the new field useful for understanding the installed hardware, but it should not be treated as a complete ownership or repair history.
