Installation error with Multiple Users

[Jl14Salvador]

I have downloaded and installed this script on an existing user on a Mac and everything works fine but then when I try to install the zsh shell and rerun the installation on a new user on the same Mac with the same Administrative rights it comes back with permission errors:

I'm currently not able to use the new shell installed by the laptop script on the new User on my Mac.

This isn't a use case we have much reason to support ourselves, but I wonder if something we're doing with the ownership of /usr/local could be better https://github.com/thoughtbot/laptop/blob/master/mac#L51-L59

A google search for "homebrew multiple users" yields many similar problems.

I am going to close this since there hasn't been any activity for a couple years. If this comes up again we can reopen. Thanks!
