I ran into the error message issue trying to update Brew via another Mac user. When I tried entering the above sudo chown -R $USER /usr/local I got:

chown: /usr/local: Operation not permitted

I found this sudo chown -R $(whoami) $(brew --prefix)/* which allowed me to perform install of brew for separate Mac user.
