I have an ancient Mac that will only take an ADB dongle. I also have an old Windows dongle for Logic 3 but I don't think that will work. I'm not sure if the Windows serial dongle for Logic 3 will fire up a Mac version of Logic 3, but even so I'd have to find a serial to ADB adapter. Does anyone know anything about that? The above probably won't work so I'm looking for either a Logic 3 or a 4 ADB dongle. If anyone has an extra one, please PM me!
