ok. there is highly respectable gentleman who is telling me that with third party ram there is high risk for it to not be compatible in future revisions of osx. he says this particularly why ocz refuses to put out a newer version of mac pro ram because apple will update the model and put them in a bad place. he also told me that this is what happened with many people with G5's a few years ago. i can't find any info of this on the net. does anyone have any knowledge of this? he is suggesting the apple has plans for the ram to evolve and they won't release 100% specs and this in turn causes many manufacturers not make newer apple ram.
