2 :: Default mac os vim lacks python3 support and many other features ,so we will be compiling vim with full features(can limit if u want)
     Verify first if Xcode developers tools are installed or not ,if not this will install it in mac
     xcode-select --install
     Now lets just move on to compiling vim from source on our distribution.
     mkdir -p .vim/src
