Ghostty tabs treated as windows.

Body

Hello! first of all, thank you for your incredible work with AeroSpace! It feels super comfortable and intuitive to use.

I found an issue tho, which is kinda annoying to me because I live on the terminal:

Steps to reproduce:

1. On macOS 26.1, open a Ghostty window and create a second tab

Screen.Recording.2025-11-29.at.12.25.25.mov

Expected result: Ghostty window takes up the entire screen
Actual result: Screen is split treating tabs as different windows

This is a known limitation of most of most tiling window managers on mac due to how accessibility api works. #68

What is the workaround for this?

[SharliBeicon]

What I've done is switching from Ghostty to Wezterm. As Wezterm doesn't use MacOS native tabs, it hasn't this problem. It is batteries-included as well, so I could avoid the use of a terminal multiplexer.

[Masstronaut]

@Thyless since ghostty is committed to using the native MacOS tabs, you can use ghostty and manage tabs inside it using a multiplexer like tmux. In this way the tabs won't be reported to MacOS, and aerospace won't try to manage them as separate windows.

I had a similar bug where a new ghostty window takes up the full screen on 0.20.0-Beta

Just use tmux 🤣

Take that ancient tech out of my sight please. I prefer taking advantage of the built-in features of my terminal without relying on third-party, tbh.

WezTerm ftw

same issue, ghosty works extremely unstable. although claudy/gemini able to recognize the app without problem, so this doesn't looks like unsolvable problem

paneru seems to have recently fixed native tabs: https://github.com/karinushka/paneru/releases/tag/v0.3.7 -- it would be wonderful if a similar fix could make it into Aerospace 👍🏼

#68 is locked so let's hope @nikitabobko see this, there are also some Aerospace forks that have fixes linked in #68
