Issue
I have tried updated virtualenv using pip3 install virtualenv --upgrade and get the big error message below.
I am using a macbook pro.

Also, when trying to see which version of virtualenv, and when I run virtualenv --version, I get the following:

Traceback (most recent call last):

    from pkg_resources import load_entry_point

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'zipp>=0.4' distribution was not found and is required by importlib-resources

What am i doing wrong?

I feel like this is because of an outdated pip installation, see #1704. However what you're typing does not add up. You're saying that you're installing virtualenv via pip3 install virtualenv --upgrade - so python 3, but then the virtualenv --version shows /System/Library/Frameworks/Python.framework/Versions/2.7/ so python 2. Use pipx instead of pip, installing packages into your operating systems global namespace is almost never a good idea https://virtualenv.pypa.io/en/latest/installation.html#via-pipx. Or create a virtual environment via (venv/or zipapp) and install virtualenv into that.
