May include adapter for MagSafe 2
Apple is now shipping a slightly different SKU of the Thunderbolt Display to first- and third-party retail stores, 9to5Mac says it has learned. Recently Apple was reported to have retired the original part code for the monitor, MC914LL/A, in favor of MC914LL/B. Because Apple hasn't made any announcements, it's unclear what might be different.
It's believed, though, that new shipments may be including a MagSafe-to-MagSafe 2 adapter in the box. Since June Apple Stores have been giving the adapter to new Thunderbolt Display customers, since the accessory is needed to pair the monitor with updated MacBook Airs and MacBook Pros. The /B part may just be simplifying the job of retail workers; Apple's online store in fact shows the adapter as included by default with new Thunderbolt Displays, but not with Cinema Displays.
