i'm in!
OS X 10.12.2
originally, i had used node-v4.2.6
but i had adapt-cli installation issues
so i uninstalled node-v4.2.6 and installed node-v6.9.2, thinking that was the fix
it wasn't
then i did the installation of the xcode tools
adapt-cli installed ok, but now i couldn't run the install script (error with something in node-v6.9.2)
so i uninstalled node-v6.9.2, reinstalled node-v4.2.6
all that was left was to make sure i had mongodb running in a terminal window
