I don't think that's true. My own surname is McIntosh, and all the family I know of come from around the Inverness area, in the Scottish Highlands, along with thousands of other McIntoshs.
I was intrigued by your assertion so I looked it up, and found this site which states "It is often erroneously said the Mc indicates Irish origin and Mac Scottish origin. In fact there is no difference at all."
