As always, the "By Identifier" method to browse Macs provides comprehensive data for Model Identifiers, Model Numbers, EMC Numbers, and more. These identifiers have been carefully hand documented, one at a time, by EveryMac.com for decades when each Mac was introduced. This original research includes hands-on inspection of the computers themselves, their packaging, and the pre-installed operating system.
To make our hand-documented data easier to view and use, it now is streamlined and subdivided by Mac series and includes tighter integration with EveryMac.com's Ultimate Mac Lookup, as well.
Of course, these identifiers are listed on applicable Mac specs pages, too.
EveryMac.com's Ultimate Mac Lookup has been updated with additional identifiers for Macs and devices from hands-on inspection and submissions by helpful readers. Thank you very much to those who contribute info. It's appreciated always.
