Those Were Mac Mini and White MacBook Part Numbers, Not Mac Pros
It seems that some the part numbers leaked earlier this week are not for the new Mac Pros, but instead for new Mac minis and White MacBooks. At least, according to 9to5Mac who originally reported the part numbers, and who has now issued a correction.
The revised part descriptions and groupings are as follows:
MC914LL/A – J59, BEST – USA - White MacBookThe original report had pegged these as "Mac Pro" part numbers instead. Meanwhile, the associated MacBook Air part numbers in the original report are said to still be considered accurate and are believed to be launching imminently.
MC936LL/A – J40, ULTIMATE – USA – Mac mini Server
MC815LL/A – J40I, BETTER – USA – Mac mini standard configuration
MC816LL/A – J40, BEST – USA Faster Mac mini
Both the Mac mini and white MacBook are overdue for updates as tracked by our Buyer's Guide. There had been few rumors about their release, though they'll certainly adopt the latest Intel processors as well as Thunderbolt interfaces.
Meanwhile, the last credible rumor for the next Mac Pro release had it pegged in early August which is only a few weeks away.
