This is the #1 most annoying thing in my recent conversion to working with a Mac. There is literally not a single way I can find to copy the current folder that I'm at in Finder for use in another finder window(ie, open/save files) nor for use in a terminal. Best bet is to two finger tap, get info, copy and paste the messed up "Macintosh HD"ized path, manually convert the Macintosh HD crap to an actual path, and then probably it works and you just wasted 1 minute of your life.
