Hi all, From all of the research I have been doing, it looks like apple uses a proprietary M.2 connector. They call M.2 SSD’s “blades” although they’re the same thing. Anyway, it doesn’t look like this can be done, but maybe someone here has successfully found a compatible one that works? I have done a LOT of research, but possibly still not enough. Some advice or help would be greatly appreciated. Thanks!
