They have yet to port it to Linux, so that's one thing that could drive them to do this same update to K1.
As far as testing things on Mac goes, I'd love to help out. I could even ask one of the coders from the JK community to help. He made the program called ModView available natively on Mac, so he knows what he's doing. If a legit thread and effort is made, I could point him to it and he could help point you in the right direction.
Short answer: no.
Disney/Lucasfilm have said that only movies and TV shows and a handful of recently released books are canon. But seeing how new content is being created for SWTOR and TSL is re-released is a good sign and could point to them being made canon. I believe they still sell SWTOR toys as well, such as Legos and Darth Revan action figures, though I could be wrong about that.
