MissionClose 0.4.0

Optional daily update checks (Updates → Check Automatically, off by default), Homebrew-aware update messages, and install instructions for Homebrew 6+ (brew trust).

Changes

• Add an opt-in daily update check
• Add Homebrew 6+'s brew trust step to the install instructions
• Document macOS 27 support and the manual update check

Install: brew trust --tap beqaabu/tap && brew install --cask beqaabu/tap/missionclose, or unzip, move MissionClose.app to Applications and open it. It isn't signed with an Apple Developer ID, so the first time macOS will block it: click Open Anyway in System Settings → Privacy & Security. Then grant Accessibility access when asked.

Changes

• Skip the Dock's empty Mission Control group on macOS 27
• Find Mission Control's thumbnails in WindowManager on macOS 27

Install: unzip, move MissionClose.app to Applications, open it. It isn't signed with an Apple Developer ID, so the first time macOS will block it: click Open Anyway in System Settings → Privacy & Security. Then grant Accessibility access when asked.

MissionClose 0.2.1

Fixes

• Runs on Intel Macs and on macOS 13 and later. Earlier releases were built only for Apple Silicon and the build machine's macOS (26), so they didn't launch elsewhere.

Under the hood

• Releases are now built, signed and published by GitHub Actions, with the same signature as before, so updating keeps your Accessibility permission.

Install: unzip, move MissionClose.app to Applications, open it. It isn't signed with an Apple Developer ID, so the first time macOS will block it: click Open Anyway in System Settings → Privacy & Security. Then grant Accessibility access when asked.

MissionClose 0.2.0

New

• Traffic-light buttons: hovering a thumbnail now shows close, minimize and full-screen buttons. Subtle by default, each lights up in its real color on hover.
• Keyboard shortcuts: hover a thumbnail and press ⌘W to close the window, ⌘Q to quit its app, or ⌘M to minimize it.
• Quit indicator: the ✕ turns into ⏻ while Option is held, so you can see an Option-click will quit the app.
• Settings in the menu bar menu: button corner (top left / top right), button size, show buttons on hover or always, and Confirm Before Quitting Apps (the first quit arms the button, a second one within 3 seconds quits).
• New menu bar icon.

Fixes

• Full screen now leaves Mission Control first, then makes the window full screen, instead of flashing and beeping.

Install: unzip, move MissionClose.app to Applications, open it. It isn't signed with an Apple Developer ID, so the first time macOS will block it: click Open Anyway in System Settings → Privacy & Security. Then grant Accessibility access when asked. Updating from 0.1.0 may require re-granting Accessibility.
