Hello, Apologies if this has been asked before (I did have a search around first). But I was considering buying a third party apple style wireless keyboard from eBay for my Macbook Pro. However on further investigation of the descriptions a lot of these are saying they are not compatible with Macbooks, but are compatible with PC's PS3's and iPad / iPhone etc.... I can't think what this would be the case, but was just wondering if anyone has any ideas? Thanks C.
