Me ran the installer and ended up with a install on my system root directory, havent seen this for a while - was like WoW! Not cool at all.

fix:

A) BEFORE running the installer:
paste into the terminal.app and commit

Code:

sudo defaults write /Library/Preferences/com.cakewalk.musicsoftware ContentDir "/Users/Shared/Cakewalk Content"
sudo defaults write /Library/Preferences/com.cakewalk.musicsoftware SampleDataDir "/Users/Shared/Cakewalk Content"

This will set "/Users/Shared/Cakewalk Content" as install root ...
Then you end up with an Rapture Pro install in "/Users/Shared/Cakewalk Content/Rapture Pro"

B) or a post install fix or an install on system root (/Rapture Pro):
paste into the terminal.app and commit

Code:

mkdir -p "/Users/Shared/Cakewalk Content"
sudo mv "/Rapture Pro"  "/Users/Shared/Cakewalk Content/"
sudo defaults write /Library/Preferences/com.cakewalk.RapturePro "Rap Multisamples Path" "/Users/Shared/Cakewalk Content/Rapture Pro"
sudo defaults write /Library/Preferences/com.cakewalk.RapturePro "Dim Multisamples Path" "/Users/Shared/Cakewalk Content/Rapture Pro"

With both variants your installed multisamples are installed to :
"/Users/Shared/Cakewalk Content/Rapture Pro/Multisamples"
and the programs/patches:
"/Users/Shared/Cakewalk Content/Rapture Pro/Programs"

If you prefer samples in other places, I'd just place a symbolic link to the destination path. example:

Code:

mkdir -p "/Volumes/ExtSamples/Cakewalk Content/Rapture Pro" # create the destination path
mv "/Users/Shared/Cakewalk Content/Rapture Pro/Multisamples" "/Volumes/ExtSamples/Cakewalk Content/Rapture Pro/" # move existing data to destination
ln -s "/Volumes/ExtSamples/Cakewalk Content/Rapture Pro/" "/Users/Shared/Cakewalk Content/Rapture Pro/Multisamples" # create a local symbolic link to external data 

This example will place the sample data on the volume
"ExtSamples"
in path
"/Volumes/ExtSamples/Cakewalk Content/Rapture Pro/Multisamples"
and symlink it to the install dir

With this setup your factory and expansion data will install the files correctly with programs on sys disk and samples on external disk.
