Spectacle M v1.0

A modern macOS menubar window manager — a SwiftUI rewrite of the classic Spectacle app.

About

Spectacle M is a lightweight, native macOS window manager that lives in your menu bar. It lets you resize and reposition windows with keyboard shortcuts — no Dock icon, no clutter. Built from the ground up in SwiftUI, it carries forward the spirit of the original Spectacle while using modern Apple frameworks: SwiftUI for the UI, Carbon for global hotkeys, and the Accessibility API for window control.

Requirements

Accessibility access (required to control other apps' windows)
Apple Silicon

Download

macOS may block the app — see installation guide below.

Installing Spectacle M on macOS (Unsigned App)

Because Spectacle M is not signed with an Apple developer certificate, macOS will block it by default. You can still install and run it by following these steps:

Step 1

Download and double-click the .dmg file to mount it.

Step 2

In the window that appears, drag Spectacle M.app into your Applications folder.

Step 3

Open the Terminal app (you can find it via Spotlight or in /Applications/Utilities/).

Step 4

In Terminal, run the following commands to remove macOS's security quarantine flag and add adhoc code signature:

sudo xattr -rd com.apple.quarantine "/Applications/Spectacle M.app"
sudo codesign --force --deep --sign - "/Applications/Spectacle M.app"
