Doesn't it require an ultra slim or something instead of the slimline? I would like to know if anyone has successfully done this on the macbook pro 15.
I suggest Googling for more, that's how I found the above.
EDIT: I should also say that because drivers are an issue (there generally aren't any readily available for OS X), you cannot (usually) simply purchase a replacement drive off say newegg and slap it in your Mac. You also might want to look at http://www.patchburn.de for indications of what 3rd party OEM drives might be swappable.
