Introduction

InjectHub is a powerful macOS utility designed to inject dynamic libraries (.dylib) into apps or binaries with ease. It provides a clean, native UI built using Swift and SwiftUI, offering tools for developers, researchers, and enthusiasts who need flexible and safe binary injection workflows.

  See real-time feedback of every operation with options to copy or clear logs.

• 🧪 Advanced Settings

  • Strip Code Signature
  • Skip Backup
  • Dummy Sign
  • Auto Dequarantine

📦 Installation

🔹 Option 1: Using .dmg Installer (Recommended Method)

1. Download the latest .dmg from the Releases page.
2. Open the .dmg — a window will appear.
3. Double-click install.sh inside the DMG to Install.

---

🔹 Option 2: Using .zip Package (Minimal Download)

1. Download the .zip file from the Releases page.

2. Unzip it — you'll get InjectHub.app.

3. Move InjectHub.app to /Applications.

4. If macOS shows a security warning on first launch, run this command in Terminal to bypass Gatekeeper & sign the app:

   xattr -cr /Applications/InjectHub.app
   codesign -f -s - --deep /Applications/InjectHub.app

---

✅ Notes

• xattr -cr removes the "quarantine" flag that macOS adds when downloading unsigned apps.
• codesign -f -s - applies an ad-hoc signature so macOS accepts the app for local use.
• You only need to do this once per download.

📋 Quick Usage

1. Open the InjectHub application.
2. Select App/File to Inject.
3. Select Dylib File.
4. Click on Inject.
5. Done ✅.
