根据Manhattan，A friend of mine说法错误？

求各位NN帮忙解答，Manhattan SC 5th P240

You should not choose Y OF X's to indicate that Y belongs to X. Choose either the form Y OF X or the form X's Y. Other grammar authorities allow Y OF X's, but this construction is considered redundant by the GMAT.

Wrong: The orca, a relative of the blue whale's, is found throughout the globe.
Right: The orca, a relative of the blue whale, is found throughout the globe.

所以说表达“我的一个朋友”必须用A friend of me，不能用A friend of mine?

理解错误，根据Manhattan，X's应为 my，而不是你说的mine。

那像是a friend of John's这样是不是对的呢？还是应该说a friend of John？

其实人家老外也很纠结这个，一般脱口而出都是这么用的。

‘The Cambridge Guide to English Usage’的解释：
The double genitive seems to serve two purposes:
emphasis. This is the effect of paraphrasing “not Jo’s fault" as no fault of Jo’s, or turning “our friend” into a friend of ours. The double genitive unpacks the phrase and foregrounds the noun rather than the person. In conversational examples such as That book of Bill Bryson’s is his best yet, the construction helps to adjust the topical focus.

clarification. Clearly a painting of Lady Rich’s and a painting of Lady Rich mean different things. The first (a possessive) makes the painting part of Lady Rich’s collection, while the second (technically an objective genitive) says that it is a portrait of the Lady herself. The duplication of the genitive is thus not redundant but clarifies the fact that the first construction is a possessive genitive.

The double genitive seems to be used more for more intimate / personal relationships than for more distant ones:
A friend / book of mine but Friends of the Earth
A friend of the president's far less common than A friend of the president*
NOT An enemy of France's but An enemy of France.

其实我觉得gmac不会考这么模棱两可的点，至少我现在还没遇到，希望对你有帮助。
