Zsh tab completion not working on Mac

Hi,
I've installed tab completion script following the commands.
```
$ curl https://cheat.sh/:zsh > ~/.zsh.d/_cht
$ echo 'fpath=(~/.zsh.d/ $fpath)' >> ~/.zshrc
$ # Open a new shell to load the plugin
```
However, even if I have ran `source ~/.zshrc`, when I type `cht.sh go/f`, the suggestion didn't show up.
Am I missing something? Thanks!


Start by reproducing the commands in the issue and inspecting the generated ~/.zsh.d/_cht alongside ~/.zshrc. Check the :zsh endpoint and the shell's completion behavior for cht.sh go/f. Done means tab completion works on macOS after following the documented setup.
