I tried to install sage on an other Mac with OS10.9.5. I compield it myself, the tests run without error. But when I try to start the notebook, the browser window opens with sage, but reports:

500: Internal server error.

The complete output of the terminal see below. The only particular thing with this Mac is that it has no (and will not have) connection to the internet.

Any Ideas waht could be the problem?

The notebook files are stored in: sage_notebook.sagenb

This is the same question as I think.

Although usually this error only shows up when one uses Sage across platforms. Can you diagnose this by doing sage -sh; echo $DOT_SAGENB in your terminal? If you truly have not used Sage on this computer, you could just remove the .sage/sage_notebook.sagenb folder with no ill effects, I think.

I did a clean install on the other Mac, and did not copy anything from the first Mac. But I tried sage some years ago.

Deleting .sage/sage_notebook.sagenb has solved the problem.

The output of the shell is

    ./sage  -sh; echo $DOT_SAGENB
Starting subshell with Sage environment variables set.  Don't forget
to exit when you are done.  Beware:
 * Do not do anything with other copies of Sage on your system.
 * Do not use this for installing Sage packages using "sage -i" or for
   running "make" at Sage's root directory.  These should be done
   outside the Sage shell.

Bypassing shell configuration files...
