Key features
Installation
Install via Homebrew to get autoupdates (Preferred)
brew install --cask nikitabobko/tap/aerospace
In multi-monitor setup please make sure that monitors are properly arranged.

[!NOTE]
By using AeroSpace, you acknowledge that it's not notarized.
Notarization is a "security" feature by Apple.
You send binaries to Apple, and they either approve them or not.
In reality, notarization is about building binaries the way Apple likes it.
I don't have anything against notarization as a concept.
I specifically don't like the way Apple does notarization.
I don't have time to deal with Apple.
Homebrew installation script is configured to
automatically delete com.apple.quarantine attribute, that's why the app should work out of the box, without any warnings that
"Apple cannot check AeroSpace for malicious software"
AeroSpace project doesn't accept Issues directly - we ask you to create a Discussion first.
Please read CONTRIBUTING.md for more details.
Community discussions happen at GitHub Discussions.
There you can discuss bugs, propose new features, ask your questions, show off your setup, or just chat.

Project status
Public Beta. AeroSpace can be used as a daily driver, but expect breaking changes until 1.0 is reached.
What stops us from 1.0 release:
Big and important issues which will go after 1.0 release:
Development

Project values
Values
- AeroSpace is targeted at advanced users and developers
- Keyboard centric
- Breaking changes (configuration files, CLI, behavior) are avoided as much as possible, but it must not let the software stagnate.
Thus breaking changes can happen, but with careful considerations and helpful message.
Semver major version is bumped in case of a breaking change (It's all guaranteed once AeroSpace reaches 1.0 version, until then breaking changes just happen)
- AeroSpace doesn't use GUI, unless necessarily
- AeroSpace will never provide a GUI for configuration.
For advanced users, it's easier to edit a configuration file in text editor rather than navigating through checkboxes in GUI.
- Status menu icon is ok, because visual feedback is needed
- Provide practical features. Fancy appearance features are not practical (e.g. window borders, transparency, animations, etc.)
- "dark magic" (aka "private APIs", "code injections", etc.) must be avoided as much as possible
- Right now, AeroSpace uses only a single private API to get window ID of accessibility object
_AXUIElementGetWindow.
Everything else is macOS public accessibility API.
- AeroSpace will never require you to disable SIP (System Integrity Protection).
- The goal is to make AeroSpace easily maintainable, and resistant to macOS updates.
Non Values
- Play nicely with existing macOS features.
If limitations are imposed then AeroSpace won't play nicely with existing macOS features
(For example, AeroSpace doesn't acknowledge the existence of macOS Spaces, and it uses emulation of its own workspaces)
- Ricing.
AeroSpace provides only a very minimal support for ricing - gaps and a few callbacks for integrations with bars.
The current maintainer doesn't care about ricing.
Ricing issues are not a priority, and they are mostly ignored.
The ricing stance can change only with the appearance of more maintainers.
macOS compatibility table
- AeroSpace binary runs on: macOS 13+
- AeroSpace debug build from sources is supported on: macOS 14+
- AeroSpace release build from sources is supported on: macOS 15+ (Requires Xcode 26+)
AeroSpace is developed and maintained in my free time.

Tip of the day
defaults write -g NSWindowShouldDragOnGesture -bool true
Now, you can move windows by holding ctrl+cmd and dragging any part of the window (not necessarily the window title)

AeroSpace 是一款 macOS 上类似 i3 的平铺式窗口管理器：它会自动把你的窗口排成树状平铺布局，并加入 i3 风格的工作区，可以直接用键盘在它们之间瞬间切换。
