For the benefit of everyone, Apple computers (MBs, MBPs, etc.) from Mainland China and Hong Kong ALL use U.S. English keyboard because in the Mainland, Chinese characters are entered using the Pinyin input method--meaning, you type their phonetic equivalent in English letters to produce their equivalent Chinese characters. Using an English keyboard, you type "ni hao" to produce "你好". Thus, Apple computers from Mainland China are identical to those being sold in the U.S.
Likewise, you don't have to worry about the language used by Mac OS because you set it up the first time you boot it up. The ONLY difference is that the computer's thin printed instruction booklet is in Chinese--which is sooo very negligible, and you can always download an English version of it from Apple.
But I must warn you, if you are buying an Apple computer from Taiwan, it might come with a Chinese keyboard, because unlike Mainland China, they use a different input method, Bopomofo (which is based on characters) and not Pinyin (which I briefly described earlier).
By the way, my MacBook Pro is from Mainland China. And it's genuine!

To be sure, either buy it from the Apple Store in Beijing, or check out their list of authorized resellers at
