Could you expand on this by any chance. Im thinking of using jriver on a mac mini then into a dac via usb. To be honest i just want to use jremote to be able to play an album. Not into fancy stuff, but want it to play bit perfect.
Relative to the OP, it doesn't appear you are asking your question from a "Mac or Windows" perspective. I believe those thinking like you, that they may want to set up a media server with MC (whatever version) running on a Mac Mini, only need to be advised that the Mac version may have quirks for a while ... it's still in beta for Pete's sake, and it doesn't even look like a Mac app! That is, MC for Windows has evolved, as has JRiver with Windows, and you can consider JRiver and MC18 to be
tried & true. It'll be some time before you can say the same about the Mac version.
You'd be better off assuming MC on the Mini will work, and ask questions specifically about "which MC-to-DAC do users find working well", or similarly about JRemote.
Regarding the OP's question, I just bought into another Windows 8 PC as a media computer running MC. It works just like I expected it would, and my Macbook connects (as a client) to my Windows MC (as a server), and it also works as it should (... except for a few quirks ...). I'd suspect sometime in the near future (late 2013, early 2014), the mac version will be just as un-quirky as the Windows version.
HTH
