I don't have any MAC here but I tried to check the warranty for my Ipad on https://selfsolve.apple.com/agreementWarrantyDynamic.do and it seems to resolve:
Estimated Expiration Date: October 27, 2012
Which is funny enough, because of EU regulations i really have 2 years guarantee, not just the 1 apple indicates But the data seems usuable.
I'm running 9.5 with the DA9.5patch54 and it still does not pick up the right information. Looking at the source for the page returned for a valid, warranted MacBook Pro Retina, it looks like the rule is looking for something that has changed.
Can you post a scan file of that machine so we can take a look at it?
I'd love to, if I knew what that is. Point me in the right direction?
Instead of getting a scan file if you can just post some of the serial numbers, we can test it off of that.
W873643XX88 (20-inch iMac with no warranty info)
W80265JVAGZ (MacBook Pro 15-inch Mid-2010 with active warranty through July 27, 2013)
C02J8502DKQ2 (MacBook Pro Retina Mid-2012 with active warranty through September 16, 2015)
In every case, DTS simply creates a number of Warranties>Warranty>N entries with "End date" of 1/1/2001 at midnight.
I am having issues with MAC warranty as well. Over 50% come back with the warranty info of an iphone that was once plugged into the system. or some Bogus date from an iphone like 1-2-1900
