The -notebook command line option takes the same arguments as the
notebook() sage command. The directory argument to both the command
line option and the sage command should be a python string. So the
proper way to write your code is
/Applications/sage/sage -notebook '"/Users/carson/doc/math/
sage_notebook/"'
Here the outer single quotes ' ' quote the python string "/Users/
carson/doc/math/sage_notebook/". This is a function of your shell.
The most recent release of Sage also accepts for example
/Applications/sage/sage -notebook '"/Users/carson/doc/math/
sage_notebook/"' secure=True open_viewer=False
This did not work for the old release of Sage.

Your code reverts Sage back to the old state.
I understand the use of two pairs of quotes is somewhat unintuitive
and inconvenient. But it is logical.
