"cd .."+Tab does not add "/" on MacOS (Sonoma)

[Marc <sedshall@xxxxxxxxxxxxx>]

Hi there,

I suppose the question must have been asked a million times already, but 
neither Google no ChatGPT brought any useful/working answers...

Opening zsh on my Mac takes me to my home directory (Users/marc/). 
Entering cd .. (+tab) should expand my input to "cd ../" (slash 
attached). However, it doesn't.

I am rather new to zsh and did not excessively mess with zshrc, so I 
don't think the problem sits there, and calling "zsh -f" seems to 
confirm this assumption as my .zshrc-setting are ignored with '-f' and 
cd ..(+tab) still doesn't work.

This is the list of option I get with setopt:

interactive
login
monitor
norcs
shinstdin
zle

What should I do to fix this?

Best,
Marc
