Don't really have an answer for you about the Mac/PC issue, though I'm pretty sure that somewhere during the ordering process for the PC game there were notes to the effect that it would only run on PC and not on other platforms--Mac, PS3, PS4. Not all games are like WoW.

Again, not all games are like WoW and not all sites are like Battle.net. RIFT is the same way as it is here. Even though I have the game and an account (which I had before the game went F2P so I had a sub), I had to register to use the forums. Perhaps Blizzard is the odd one out here? Just a thought!
