Nathan, thank you very much for your answer. I have some comments:

1. There is something wrong with Jupyter in my Mac. I do not know what it
is. I manage to run it but
it can not upload files (that do upload in the Terminal version of Sage).
So if I can make the Terminal
version of Sage work, it would be great.

2. Regarding the gap issue (kbmag) In my old version of Sage I run the
following commands in order to work:

In a terminal:

/Applications/SageMath/sage -i gap_packages

Then in sage:
libgap.eval(‘LoadPackage(“PackageManager")')
libgap.eval('InstallPackage("kbmag")')

Now loading `kbmag` works:

    sage: libgap.eval('LoadPackage("kbmag")')
    true

But sadly the first step (sage -i gap_packages) does not work now. That is
why, I think, everything fails after that.
Moreover, after that line, my sage does not start anymore and I have to
reinstall it.

I hope I have explained my problem clearly. I definitely can use some help.
Best,
Anita
