So when I started emacs from the terminal, I used Options -> Keep in Dock to keep that in the dock instead of /Applications/Emacs.app. Starting the former, I again did not have TAB-completion, so it only works when (really) starting emacs from the terminal (which is funny cause I thought I can get rid of the Mac's terminal since I have a shell in emacs...)

Okay, in the meantime, I tried something like:
(setq exec-path (getenv "PATH"))
but that of course failed.
I then put in:
(setq exec-path (append exec-path '("/opt/local/bin"))); set exec-path
(setenv "PATH" (mapconcat 'identity exec-path ":")); set PATH
and restarted emacs. Still no TAB-completion :-(
If that helps, I originally had the following to get the same PATH as in the terminal:
(setq explicit-bash-args (list "--login" "-i"))
(that with the seq exec-path command above also did not work, though)
I'll try what you suggested in your recent mail, soon.
