Then go to STYLUS RMX DISC 1 and copy the content of the SAGE folder(namely: SAGE Libraries and Stylus RMX folders) into your recently created SAGE fodder. Mount both discs from your Spectrasonics Stylus RMX 1.5 Full Library with update 1.9.5d PC MAC folder ( namely: dyn-rmx15d1.iso found in DISC 1/StylusRMX15_D1/1.5.1-DYNAM iCS as well as dyn-rmx15d2.iso found in DISC 2 bla, bla, bla).
) You can create it in Documents, for example. RUN IT! Then go to your macintosh hd drive and create a folder called SAGE anywhere you want.( I created it in Library/Applications Support. Inside this folder you are interested in the installer called Stylus RMX v1.6.0 Intel.dmg. Inside you fill find another folder called Stylus RMX 1.5 Install, which contains a folder named MAC. You will get a folder named Stylus RMX Update & Crack.
Go to your Spectrasonics Stylus RMX 1.5 Full Library with update 1.9.5d PC MAC folder, then go to updates and extract the StylusRMX15_setup_.
You dont need the original installer, since you cant download it anyway. MAC USERS: I Finally I figured this one out!!!! Im running OSX LION.
