Eshell works, but it does not use term.el, and so has terminal compatibility problems with many utilities (the progress indication of curl or homebrew, for example). I have found it much more practical to stick with zsh, but use ansi-term or multi-term to launch the shell from inside Emacs windows. Performance in situations when the terminal wants to spit out a lot of output leaves much to be desired, but the convenience of staying inside Emacs outweighs the drawbacks.
