Aerospace support on macOS Tahoe (macOS 26)

[amantinband]

Body

Hey guys! Don't see an existing issue so dropping this here - has anyone tested on macOS Tahoe?

Just updated to the latest developer beta and other than the windows resizing nothing else seems to work

[adusak]

Hello, I've been trying to use it for 2 days now, and for me, it mostly works (in terms of my workflow). The biggest issue I have observed so far is ghost windows detected by Aerospace. When I list windows in a workspace, it outputs windows from apps I killed. That is causing the actually visible windows to be resized.

[TheNetAdmin]

Nice workaround! I further developed such small python script, and bind it to alt-g keybinding by alt-g = 'exec-and-forget python3 ~/bin/aerospace_cleanup.py cleanup'

So whenever I observe a weird ghost window, I just alt-g and it's gone:

import typer
from invoke import run
from typing import Dict

app = typer.Typer()

@app.command()
def cleanup():
    res = run("aerospace list-windows --all")

    def parse(w: str) -> Dict[str, str]:
        id, name, title = w.strip().split("|")
        return {
            "id": id.strip(),
            "name": name.strip(),
            "title": title.strip()
        }
    
    windows = [parse(w) for w in res.stdout.strip().split("\n")]
    windows = [w for w in windows if len(w["title"]) == 0]

    for w in windows:
        run(f"aerospace close --window-id {w['id']}")

[PaulvSchaik]

@TheNetAdmin I get the error: ModuleNotFoundError: No module named 'typer'

I now use 'close-all-windows-but-current' bound to alt-q a lot and it makes it workable, I don't have a whole lot of windows open.

[mblarsen]

@PaulvSchaik here is a version that doesn't require external libs.

import subprocess
from typing import Dict


def cleanup():
    res = subprocess.run(
        ["aerospace", "list-windows", "--all"], capture_output=True, text=True
    )

    def parse(w: str) -> Dict[str, str]:
        id, name, title = w.strip().split("|")
        return {"id": id.strip(), "name": name.strip(), "title": title.strip()}

    windows = [parse(w) for w in res.stdout.strip().split("\n")]
    print(f"{windows=}")
    windows = [w for w in windows if len(w["title"]) == 0]

    for w in windows:
        subprocess.run(["aerospace", "close", "--window-id", w["id"]])


if __name__ == "__main__":
    cleanup()

[fozyus]

I have written this one

#!/bin/bash
# script to find and close ghost windows

ghost_window_ids=$(aerospace list-windows --all | grep -e '.*|.*| $' | awk '{print $1}')

for id in $ghost_window_ids ; do
    aerospace close --window-id $id
done

[PaulvSchaik]

These 2 work great @mblarsen @fozyus ! Thanks!

EDIT: This issue is unrelated to aerospace

Okay so I did some more testing and seems like (for me) this is the status:

Works

• Switching node orientation: 'layout tiles horizontal vertical'
• Switching node orientation 'layout accordion horizontal vertical'
• Resizing tiles: 'resize smart'
• Switching between workspaces: 'workspace'

Doesn't work

• Fullscreening a node: 'fullscreen'
• Moving nodes between workspaces: 'move-node-to-workspace'
• Moving focus between nodes: 'focus'

EDIT: This issue is unrelated to aerospace

@nikitabobko I did some more testing and I see that on Tahoe, my custom mappings with ctrl+shift don't work. Once I change the mapping to anything else - it works. This is the shared issue with all the Doesn't Work above:

Doesn't work

• Fullscreening a node: 'fullscreen'
• Moving nodes between workspaces: 'move-node-to-workspace'
• Moving focus between nodes: 'focus'

[amantinband]

oh never mind it was skhd swallowing the events! Yikes, sorry for that. I'll edit the messages above

[nikitabobko]

I have checked Tahoe in virtual machine (UTM) and I couldn't find a thing that would be broken

And it's only the 1st Beta

[adusak]

The problem with ghost windows usually shows up after some time of usage, starting and quitting apps.
This is how listing windows for a workspace usually looks, the only actually running app was Xcode.

I'd be happy to provide whatever diagnosting info might be needed to troubleshoot this. But I know that chasing bugs with developer betas can get very tedious and unproductive.

[WolffTech]

I'm seeing the same thing as well with ghost windows, below is a video of the issue. It seems that you can close out these ghost windows with using a hotkey with close on it through Aerospace. If you close out a window with Cmd + W or hitting the red button to close it, it creates a ghost window. As always thanks again nikitabobko for your work on this project and if there's anything I can provide that might help please let me know.

[ifeichuan]

I've found an issue: when using the Alt+Tab function, an error combination related to Alt+Tab and aerospace causes a thin line to appear in the Alt+Tab preview window for windows not on the active desktop. Windows on the current desktop display normally. All are the latest versions, and this occurs on macOS Tahoe develop beta.

[ifeichuan]

[ifeichuan]

Perhaps this error is not related to aerospace; however, I would like to briefly mention it.

[shsw228]

It sometimes stops working. Also, the node application appears in the Dock and appears to be hanging. Force Quit to work again. 26.0 Beta (25A5279m)

ps. I've added the version of node.js. -> v24.2.0

[SConaway]

I don't think this is related to Aerospace at all as it happened last beta cycle -- before I used Aerospace. I've run into it occasionally with other (non-Raycast) node processes too.

[WolffTech]

This is from the MacOS beta and not really related to Raycast or Aerospace, in my opinion. This same thing happened during the last developer beta. I think it has to do with Apple enabling verbose logging on most processes during the beta. It should go away in a future beta update. There were a lot of people mentioning it during the last developer beta, but I never saw a concrete answer as to the cause. See npm/cli#7690 for an example.

[shsw228]

Sorry for talking without any proof. I didn't know if this was limited to Raycast or not.
I meant to say that it was within my own observations.
It may be that WolffTeck is right, but in any case, it's frustrating that we can't do anything about it :(

[shsw228]

Tahoe DB2, it may be fixed.

[Eveeifyeve]

It's any node application that is built or anything that is ran with node package managers nodejs/node#58798.

[s1nny0ur]

Beta 2 seems to have fixed a few issues, node tasks not in taskbar is fixed for me.

[s1nny0ur]

Ghost windows also seems fixed but i will report back after some more time using it.

[fozyus]

yeah, just updated all isuues with ghost windows + node running in dock are gone

[Eveeifyeve]

I will still keep this issue open: nodejs/node#58798 I will add a comment to suggest to update to beta 2.

[Eveeifyeve]

Still broken parts, like I can still see the other application if tho it's in the other workspace.

[strayer]

This is a feature: https://nikitabobko.github.io/AeroSpace/guide#emulation-of-virtual-workspaces

For better or worse, macOS doesn’t allow to place windows outside the visible area entirely. You will still be able to see a 1 pixel vertical line of "hidden" windows in the bottom right or left corner of your screen. That means, that if AeroSpace crashes badly you will still be able to manually "unhide" the windows by dragging these few pixels to the center of the screen.

[Eveeifyeve]

Is there an option to say I want to hide the window and show the window when I am in the workspace so it doesn't show at all but hides it to tray?
