Added a working way to run the installer on MacOS

[ilyassesalama]

It seems like the current explanation of how to run the installer on MacOS is just wrong. I made a few changes to add a real working way.

while MacOS is the way it is stylized, the instructions are perfectly fine as they are, this is just overcomplicating things

The current instructions are NOT working. I did try what was instructed on my Mac before opening this PR, and they don't work.

skill issue

I'd say calling my change "overcomplicating things" is the skill issue here. Average Discord user.
