Hey I have the same problem as David VG!
When I try to install EZ drummer 1, I get an error message stating that i should upgrade my OSX to at least 10.5….I am currently having OSX 10.10!!
Plz help me!
P.s. I guess my EZ drummer version is 1, can not see any number on the package. Serial numer: 8-25810-00106-7
