poser 7 violated OS X canons regarding use of applications folder.   PP2014 installer was adjusted to obey them; in effect they cleaned it up.  each of three runtimes has its purpose, but give it time.  it takes patience to adjust to changes, and you'll enjoy poser more as you ease into it.

I found it's easier to have hundreds of runtimes with distinctive names, rather than trying to lump 100GB of items into one runtime.
