I'm no expert on the Mac binaries, but I believe you need to use
FEniCS from the special FEniCS icon that gets installed in your
applications folder. Then you will get another version of Python.

The error messages above seem to indicate that you are running a
Python from Fink (?) and that you have an old conflicting version of
DOLFIN installed (where Constant expects two arguments instead of
one).

What is in demo6.py?

I also see that you are using Python from Fink (/sw/bin/python). The Mac binary will only work with system Python. You will need to remove/comment out anything Fink related in your ~/.profile and ~/.bashrc. Did you run the demo from the terminal you get by clicking on the FEniCS icon or did you source the file /Applications/FEniCS.app/Contents/Resources/share/fenics/fenics.conf
?

Thanks Anders.

Yes, I have an old installation of fenics. How do I uninstall it?

Yes, I forgot that I should open the terminal using the fenics app.
In fact, it fails to open with a warning that I am using the wrong
python.

Johannes also pointed this out. But how do I change to the correct
python?

My ~/.profile is

test -r /sw/bin/init.sh && . /sw/bin/init.sh

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

source ~/Work/FEniCS/dolfin-0.9.0/dolfin.conf

I have no ~/.bashrc. It points to the old fenics. Regards. /stig

This is the line you need to comment out:

  test -r /sw/bin/init.sh && . /sw/bin/init.sh

Simply add a # in front of it:

  #test -r /sw/bin/init.sh && . /sw/bin/init.sh

You should also do the same for this line:

  source ~/Work/FEniCS/dolfin-0.9.0/dolfin.conf

It works! Thanks! /stig

Great! It is nice to see that someone is trying out this Mac binary. This is actually the first response after about 140 downloads.

Btw, could you change status to 'solved'?

Thanks Anders Logg, that solved my question.
