Apple/Mac/book compatibility lists are concise and reasonably up-to date, mainly because the list of compatible kit is relatively small .....Because PC is a third party component based industry , it has literately tens of thousands of compatible components that has to be categorized and constantly tested ..... no company has the time and resources to cover everything .....all they can do is rely on JEDEC to set strict enough parameters for overall compatibility throughout the industry
does that satisfy your curiosity ?
