Virtual Machines and Hackintosh Systems

LeetDown is not compatible with virtual machines. Some hackintosh systems were successful running LeetDown, though, exploiting issues you encounter on environments other than real Mac hardware is up to you to resolve. Please do not open an issue for this.

Installation

Mount the LeetDown_[VERSION].dmg and drag the LeetDown.app to your /Applications folder.

Follow the instructions shown in the app.

Troubleshooting

A7 devices and Apple Silicon Macs

• Due to the USB stack of ASi macs, the device will disappear after LeetDown uploads iBSS. When you get the prompt [+] Device was lost, reconnect the USB cable to your mac to resume the upload process, do what it says and the restore will resume automatically.
• Make sure to reconnect the cable to your mac. You don't need to replug the cable to your iOS device.

Stuck at exploiting or exploitation failure

• Make sure you're not using any USB Hubs or type-c to lightning cables. If your mac has only USB-C ports, use a lightning to type-a cable with a USB type-c to type-a converter.
• Make sure you're not running LeetDown under a virtual machine. Check compatiblity here.
• Re-enter DFU mode and try exploiting again with LeetDown.
• If it's still not working, download iPwnder-lite and exploit your device manually.

Failed to restore device

• Update to latest iOS version with iTunes/Finder/idevicerestore then try again.
• Check if your USB cable is working fine.
• Try with a different USB port (or adapter if running on Apple Silicon).
