If you can find a MacOS D-50 librarian program it should. Sending Sysex over midi works under Mac. As I don't own a Mac I can't recommend any software though. The D-50 Librarian I use is windows only. So for that you need bootcamp or a vm or something like that. Probably best to Google a bit to see if that software exists or if there's a way to run the windows program on your machine.
The link is for librarian software, not for this card.😢 Where to buy this card?
Depends on where you live but this should point you in the right direction 👍🏻
