Cercando di aggiornare homebrew, ottengo questo:
$ brew update
error: Your local changes to the following files would be overwritten by merge:
.gitignore

Please, commit your changes or stash them before you can merge.
error: The following untracked working tree files would be overwritten by merge:
CONTRIBUTING.md

Library/Aliases/heroku
... ecc.
Un modo per ripulirlo? Sembra che usi git sotto il cofano?
