I did make it easy for myself I guess.

Poser Pro 2012 installed to the default: Applications folder (where else on a mac?).

"Poser Pro 2012 Content" folder installed to the default: /users/shared/

All my runtimes are "internal" at present... by which I mean, they're inside that "Poser Pro 2012 Content" folder.

I have one big terrabyte disk and only been accruing content since this time last year... so its not totally full yet
