Hi George
to install the EXS24 instruments and Samples onto your Macintosh computer.
1. Drag and drop the sample library’s EXS24 Instruments folder into the “Sampler Instruments” folder located at HD/Library/Application Support/Logic/Sampler Instruments/.
2. Drag and drop the sample library’s Wav Files folder into the Sampler Files folder located at HD/Library/Application Support/Logic/EXS Factory Samples.
Once you’ve done this fire up logic and open exs24 and browse for the instrument through exs24. and you should be good to go.
Hope this helps
