Thunderbolt-to-FireWire adapter still off store
(Updated with Thunderbolt-to-FireWire availability) Apple appears to have restored new build-to-order options for the lower-end model of the Retina MacBook Pro. At the company's online store, shoppers can now scale the processor up to a 2.6 or 2.7GHz Core i7, or the SSD up to 512 or 768GB. Apple is moreover allowing any new Mac buyer to have Pages, Numbers, or Keynote pre-installed.
The extra BTO options appeared on the store earlier, but were removed shortly after they first went live. Still missing is a Thunderbolt-to-FireWire adapter that also showed up on the store this morning.
Update: The adapter does appear to be on sale, but only some visitors to Apple's website are seeing it.
