A native, open-source macOS utility to quit running applications instantly, built with SwiftUI.

This isn't a massive project built by a seasoned developer—it's a small, cute utility born out of a simple frustration.

As a designer (I'm designsbymuzeer), I was tired of the hassle: after closing Figma, VS Code, and a dozen utility apps, I still had to manually hunt down every single open app to quit it and reclaim my system's focus. It felt like digital clutter was winning.

I realized I didn't need to be a "super dev" to solve this. Utilizing modern tools and a clear design vision, I built Bye—a tiny menu bar companion that is fast, intuitive, and visually native.

This project is simply my solution to a common community problem, and I'd love to share it with anyone who values a clean workspace. Enjoy!

• Native & Lightweight: Built using modern SwiftUI for a minimal footprint and near-zero CPU usage when idle.
• Instant Quitting: Quit all running user applications with a single click.
• Selective Control: Easily click to select or deselect specific apps you need to keep open.
• Adaptive Design: Features a glass-morphic interface that seamlessly adapts to Light and Dark Mode.
• Open Source: Full source code available here for transparency and collaboration.

1. Download the latest Bye.zip file from the Releases Page.
2. Unzip the file.
3. Drag the Bye.app file into your /Applications folder.
4. Important: On first run, you may need to Right-Click the app icon and select Open to bypass the "Unidentified Developer" warning.

If you wish to build the app from source:

1. Clone this repository: https://github.com/designsbymuzeer/Bye-Mac-App.git
2. Open the project file (Bye.xcodeproj) in Xcode (macOS 14.5+).
3. Build and Run (⌘ + R).

Bye is a modern macOS application built exclusively with Apple's native frameworks:

• Language: Swift 5.8+
• Frameworks: SwiftUI (for the UI) and AppKit (specifically NSWorkspace for process management).
• Compatibility: macOS Ventura (13.0) or newer.

This happens because the app is not submitted to the Mac App Store and has not been notarized by Apple (which requires a paid developer account).

The Fix (You only have to do this once):

1. Do NOT drag the app into your Applications folder yet.
2. Right-Click the Bye.app file.
3. Select Open.
4. A new warning dialog will appear. Click the Open button to grant permission.

The first time the app is run, it needs permission to set up the necessary background service to monitor application changes. This is standard for menu bar utilities.
