these days I want to buy a blu-ray player software, there are lots of products of different brands, which make me confusing! and I don't wanna watch the reviews one by one, can anyone give me advice?
Blu Ray has had it's decryption keys openly available since 26 December 2006, I think you'll find that VLC has had Blu Ray support since 2007.
That doesn't directly address what I asked. Your statement does not invalidate what I said regarding downloading from elsewhere and problems installing under El Capitan. The post below yours provides support to my comment.
Without a Blu-ray drive I can't test any of this.
Of course, you will need a Blu Ray drive to play a Blu Ray disk. That should be self-evident even to my Australian relatives.
If you are capable of installing and using Onyx, then you have solved your problem.
I imagine Onyx has absolutely nothing to do with this thread and what we're discussing. You still haven't answered my questions, I'll assume you don't know but decided to weigh into the conversation anyway.
I was looking into this recently because I have been considering buying a Blu-ray drive. Isn't it more complicated than you say? Namely the decryption keys are not contained within VLC so you have to download them elsewhere, and then the key package installer tries to install them into a SIP protected folder under El Capitan and so fails.
Correct me if I'm wrong, I would like to know myself.
