Hi, I got this old Yamaha keybord that I would like to use on my macbook pro. The keyboard is from 2004. I downloaded the driver for the keyboard and installed this, but when I try to open it in system settings it say that it doesn't work on an Intel-based Mac. I found out that Macbooks before 2006 had the PowerPC processor. Now I wonder, is it possible somehow to make this keyboard work?
