“We’ve gotten word that Apple has slightly tweaked its Thunderbolt Display SKU, and these units have begun shipping to Apple Stores and Apple Official Resellers worldwide. The change was first noticed by our sources when Apple retired the Thunderbolt Display‘s MC914LL/A part code and replaced it with MC914LL/B just a couple of days ago.”
Alternatively if you ordered a new Thunderbolt Display and it has yet to arrive at your home, and you discover it does not come with the adapter, you will able to purchase it via Apple’s website or at an Apple retail store for only $10. Not really a big deal but we’re sure it’s a convenience that new MacBook owners will probably be able to appreciate.
