Kext-Drop

Kext-Drop is a macOS utility that allows you to easily install kernel extensions to /System/Library/Extensions/ or /Library/Extensions/ using a simple drag-and-drop interface.

Overview

Installing kexts to the system extensions directories traditionally requires terminal commands and manual permissions management. Kext-Drop simplifies this with a graphical interface — just drag your kext onto the app and it handles the rest.

Features

• Drag-and-Drop: Simply drag kexts onto the app to install
• Dual Locations: Install to either /S/L/E or /L/E
• KDK Management: Automatically downloads and installs the Kernel Debug Kit when needed
• Snapshot Support: Includes Revert Snapshot and Re-Patched-System utilities
• Wide Compatibility: Works from macOS Catalina 10.15 through macOS Tahoe 26

Requirements

• Gatekeeper must be disabled
• SIP (System Integrity Protection) must be disabled
• Working Ethernet connection for KDK downloads (on /S/L/E for Ventura and later)
• For snapshot disk: Disable AMFI via amfi=0x80 boot arg or AMFIPass.kext
• csr-active-config set to 03080000 in config.plist

Installation

1. Download the latest release from GitHub
2. Open the downloaded application
3. Drag the kext you want to install onto the Kext-Drop window
4. Choose the installation location (/S/L/E or /L/E)
5. Follow the on-screen prompts

Use Case: AppleHDA on Tahoe

A common use case is installing AppleHDA.kext on macOS Tahoe to restore analog audio (since AppleHDA was removed from Tahoe):

1. Ensure AppleALC, Lilu, and your layout ID are configured in OpenCore
2. Use Kext-Drop to install AppleHDA.kext to /System/Library/Extensions
3. Reboot and verify audio is working
