Yes that is because Apple promises that everything works iff you buy hardware and installation of it from them. I changed a RAM module once and hibernation stopped working, Apple says that is because it's not the identical RAM-module they sell. So their list of supported hardware is pretty small

Historically there have been sites that tell you which RAM modules work with OS X. It's usually the higher end stuff, but then again the modules that come with OS X tend to be better than average to begin with.

As I've gotten older, and am not having to pinch pennies quite as badly, I just buy Apple expansion hardware from the places that specialize in it. I was refurbing one MacBook Pro of some era (2012 maybe?), and it simply would not play nice with an ADATA SSD (recognized it, but data transfers were so slow the OS wouldn't install - known issue, apparently). I saved a bit compared to the OWC option, except I wasted an afternoon of messing around and had to buy the OWC option after all.

Some RAM modules not working at all makes sense, though.

A module working for everything except hibernate is ridiculous.
