I came across this little app - coconutIdentityCard (i think someone posted a link on here previously) Anyway, it's a little app that's supposed to tell you where/when your Mac was built. Where does it get this information from? My recently purchased Rev B iMac G5 refurb claims it was built in the USA between 12.01.2004 and 18.01.2004. Hmmm.... the iMac G5 Rev B was first released mid-2005 and even the rev A G5 came out late Aug 2004. I definitely have a rev B machine. I'm just curious as to where it pulls this date range from.
