localhost still showing despite not being added or explicitly turned off

[venvaneless]

I am not requesting help with my configuration and believe something is genuinely broken.

• Something is really actually broken.

Is there an existing issue outlining your problem?

• I have searched the existing issues and troubleshooting guide, and they do not solve my problem.

Describe your problem.

I don't know if it's my config or the theme, but I can't seem to make the localhost (Macbook.local) disappear from my bar.

My config is the standard one on your main page I used to test if everything is working.

Paste your configuration.

~/.tmux.conf

Options to make tmux more pleasant

set -g mouse on
set -g default-terminal "tmux-256color"

Configure the catppuccin plugin

set -g @catppuccin_flavor "mocha"
set -g @catppuccin_window_status_style "rounded"

Load catppuccin

run ~/.config/tmux/plugins/catppuccin/tmux/catppuccin.tmux

For TPM, instead use run ~/.tmux/plugins/tmux/catppuccin.tmux

Make the status line pretty and add some modules

set -g status-right-length 100
set -g status-left-length 100
set -g status-left ""
set -g status-right "#{E:@catppuccin_status_application}"
set -agF status-right "#{E:@catppuccin_status_cpu}"
set -ag status-right "#{E:@catppuccin_status_session}"
set -ag status-right "#{E:@catppuccin_status_uptime}"
set -agF status-right "#{E:@catppuccin_status_battery}"

run ~/.config/tmux/plugins/tmux-plugins/tmux-cpu/cpu.tmux
run ~/.config/tmux/plugins/tmux-plugins/tmux-battery/battery.tmux

Or, if using TPM, just run TPM

Attach screenshots.

No response

What tmux version are you seeing the issue on?

tmux 3.5a

What shell are you using?

zsh

Any additional comments?

I also tested this to see if it will disable all modules, but it doesn't work either:
set -g @catppuccin_status_modules ""

I had this same problem. You can fix it by following the instructions here https://github.com/catppuccin/tmux/blob/main/docs/guides/troubleshooting.md
Just put the two lines in there into your config

I'm a bit confused that supposedly this is for showing the window title:
set -g @catppuccin_window_text "#W"
set -g @catppuccin_window_current_text "#W"

... but my window title is not .zsh in the first place, see first screenshot:

For anyone who has the same issue with .local session name appearing, my problem was indeed that this:
set -g @catppuccin_window_text "#W"
set -g @catppuccin_window_current_text "#W"

.. didn't load before this:

Load catppuccin

run ~/.config/tmux/plugins/catppuccin/tmux/catppuccin.tmux

... hovewer I'm still not able to completely remove the middle icon, the colored one with .zsh (see second screenshot:)

I tried using this:

Turn off middle icon

setw -g window-status-format ''
setw -g window-status-current-format ''
set -g window-status-separator ''
set -g @catppuccin_window_text ""
set -g @catppuccin_window_current_text ""

But now it just shows "0", instead of disappearing completely:

I am a bit confused about what you are trying to ask for. Are you saying you want to get rid of the purple capsule that shows what session you are on? I feel like you would want to keep that to keep track of sessions, but if you want to get rid of it, remove this line from your config

set -ag status-right "#{E:@catppuccin_status_session}"

I am facing the same issue on macOS 26

Summary
With Catppuccin for tmux enabled, the left window list renders my hostname (e.g., MacBook-Pro.local) instead of the window’s name. However, tmux display -p '#{window_name}' returns the correct value (tmux-plugins). This suggests the theme’s window list format is using host (e.g., #h / #{b:pane_current_hostname}) rather than #W.

What I expected
The window tab/bubble to display the tmux window name (#W) or to have a theme option to choose #W vs host.

What actually happened
Bottom-left shows the hostname (e.g., 0 MacBook-Pro.local), while #{window_name} is tmux-plugins.

Steps to reproduce

1. Install and enable Catppuccin tmux.

2. Minimal config:

   set -g mouse on
   set -g default-terminal "tmux-256color"
   set -g @catppuccin_flavor "mocha"
   set -g @catppuccin_window_status_style "rounded"
   run '~/.config/tmux/plugins/catppuccin/tmux/catppuccin.tmux'
   
   set -g status-left ""                      # keep left segment empty
   set -g status-right '#{E:@catppuccin_status_application}'

3. Start tmux, rename the window to tmux-plugins (C-b ,).

4. Observe bottom-left bubble shows MacBook-Pro.local (hostname).

   Both formats appear to include a hostname token (e.g., #h / #{b:pane_current_hostname}).

@ambakick I would refer to this ^

Just add the two lines of code into your config and it should show the actual window name.
