Offline Apple serial number database

Apple's serial number lookup page was down today, first with a looping GIF saying "We'll be back. We're busy updating our support tools and will be back soon." in 19 different languages and later with a page simply stating "We are unable to complete your request at this time."

Needing to identify a Mac but unwilling to use a third-party web service, retrieved the serial number via dmidecode -s system-serial-number in GParted Live then searched OpenCore's modelinfo_autogen.h for the last 3 characters (8QR), which corresponded to "MacBook (13-inch, Aluminum, Late 2008)".

While the model identifier can be obtained via dmidecode -s system-product-name (in this case "MacBook5,1" which Mactracker also reports as "MacBook (13-inch, Aluminum, Late 2008)"), some identifiers like "MacBook5,2" correspond to multiple models ("MacBook (13-inch, Early 2009)" and "MacBook (13-inch, Mid 2009)").

Note that Apple replaced structured serial numbers with randomized ones in 2021:
