There are two (at least) library folders. System wide ones, and user specific ones. The user specific one sits on your home folder, and is hidden. I recommend you put the profiles in the system wide folder (in case you have more that one user on the Mac, because then all users can use the profiles).
Open a Finder window, and press command and the up-arrow until you see Applications, Library, System, Users. The go to Library - ColorSync - Profiles, and copy your profiles in there.

There is another folder in System/Library/ColorSync/Profiles. That one would work too.

If you need to access the folder inside your user home folder (for example because the software has placed profiles there), just open the menu "Go" and hold the alt (option) key pressed, and you can select the Library folder in the menu. The folder will magically show up in the Finder window.

Hope that helps.


btw another recommended setting: Go to Finder - Preferences, Advanced Tab and select "Show all filename extensions". I prefer to see what is a jpg vs tiff vs .doc
