[BUG] preview directory content always shows 'Loading...' on MacOS

[serpro69]

Describe the bug

See screenshots below.
I have the same config on Linux and Mac, and it works fine on Linux (see expected behavior screen), but does not on a Mac

I can make sure:

• I am using the latest version of fzf-tab
• this is the minimal zshrc which can reproduce this bug
• fzf-tab is loaded after compinit
• fzf-tab is loaded after plugins which will wrap Tab, like junegunn/fzf/completion.zsh
• fzf-tab is loaded before zsh-autosuggestions, zsh-syntax-highlighting and fast-syntax-highlighting.

To Reproduce

• cd <TAB>

Expected behavior

Screenshots

Environment:

• OS: Darwin razorback.local 24.2.0 Darwin Kernel Version 24.2.0
• zsh version: zsh 5.9 (arm64-apple-darwin24.0)

Minimal zshrc

I have the following line that enables preview on cd completions:

zstyle ':fzf-tab:complete:cd:*' fzf-preview 'eza --icons=always --width=1 --color=always $realpath'

Plus the following that enables tmux popup (though the behavior is the same with or w/o the tmux popup)

zstyle ':fzf-tab:*' fzf-command ftb-tmux-popup
zstyle ':fzf-tab:*' popup-min-size 80 16
