Ripping SACDs requires sacd_extract to be used, which is available cross-platform (looks like you'd probably have to compile it yourself for the Mac). I think ISO2DSD is an alternative that is available for Windows and Mac (requires Java to run), so that might be worth looking into. But there's work involved ripping SACDs via the Terminal over the network to get it done - I've never ripped SACDs, but have read those guides.
Ripping CDs (not SACDs), as far as I know, only works with optical CD/DVD/Blu-Ray drives directly connected to a PC or Mac. Whereas ripping SACDs with an Oppo looks like it's done over the network instead. Not sure it's even remotely possible to rip CDs via a player like an Oppo 105 to a PC or Mac if it's directly connected via USB but I wouldn't be surprised though if this isn't possible (lack of drivers, perhaps?).
