On my new mac machine, I could not do autocomplete for Git when I hit Tab.
So I thought to modify the terminal and found certain things on this link.
I may have messed when I installed iTerm2, Oh-My-ZSH, and Solarised Dark. So now I have nice looking terminal and git autocompletion works.
But in the terminal, the user name, machine name etc does not appear, like it is the in above link.
The colour scheme is also not great.
I am very new to Mac and please assume that I know very little about how it works.
