Signature issue ⚠️

Zapp is open source software and is safe, but due to Apple's strict inspection mechanism, you may encounter warning interception when opening it.

If you cannot open it, please refer to the Apple manual Open a Mac app from an unidentified developer, or perform local code signing.

Local code signing for macOS

Install Command Line Tools:

xcode-select --install

Open the terminal and execute:

sudo codesign --force --deep --sign - /Applications/Zapp.app/

"replacing existing signature" indicates successful local signing.

Build it yourself

1. Clone this project:

git clone https://github.com/liopoos/Zapp.git

2. Open Zapp.xcworkspace with Xcode and build it yourself.

Usage

Zapp is a menu bar application, so you need to click the menu bar icon button to operate it. Zapp currently provides three ways to decode QR codes:

Method	Shortcut	Description
From screen capture	⌘+X	Capture the screen QR code through the system screenshot application
From clipboard	⌘+C	Decode the image from the clipboard
From iPhone or iPad	⌘+Q	Use the "Continuity Camera" API to call the camera of the iPhone or iPad under the same iCloud to take a photo

Security

Zapp saves the decoded content locally and the application itself does not perform any network connection.
