Then change your user to use it as its shell with chsh (this is blatantly obvious, but modify the 'Shell' line to point to /usr/local/bin/bash). $ sudo bash -c 'echo /usr/local/bin/bash > /private/etc/shells' First, register the new binary as a valid shell: You can also install via MacPorts or Fink, I imagine, but I try to do these things myself when possible, if only for the sake of transparency. The binary is installed at /usr/local/bin/bash. On my system (Leopard + Xcode) I had no trouble compiling. Here's how I upgraded my system and a few ways I use the new features.

So far the things I use most are the '**' recursive globbing and the 'autocd' option. bashrc is sourced which is what in turns sources Nix. I can successfully install it, and it loads the version installed by Nix, but if I try to use any feature from Bash 5.x (the updated version) Im unable to unless.
