RME has just release their new drivers for the next macOS Catalina. Then we just need DIGICheck 64-bit for macOS10.15, I've been. Although not supplied on the CD, Mac drivers were available from the web site, including the v1.1 Mac OS X drivers. Also included on the disc was the Digicheck and Meter Bridge software (see below), a flash ROM updater program, and the 41-page manual in Adobe Acrobat (PDF) format.
