checkra1n on PC/Linux via QEMU macOS Virtualization

Tutorial Guide checkra1n macOS on PC using QEMU and USB Passthrough: https://downthecrop.xyz/blog/tutorial-how-to-run-checkra1n-on-linux-via-qemu-macos-virtualization

EDIT: I have now successfully achieved checkra1n on Ubuntu Linux 18.04 using QEMU and IOMMU Pass through. Installation scripts coming soon!

I have a work around using a live Linux USB. There is no offical release for Windows and Linux currently so macOS must be virtualized using KVM and IOMMU groupings.

Watch my YouTube video explaining my virtualization approach

The checkm8 jailbreak implementation called checkra1n was released Sunday November 10th 2019 but only for macOS. This wasn't done to spite non-apple desktop users. The checkm8 exploit relies of precise control of the desktop USB stack to manipulate DFU mode.

Due to the precision of this communication they needed to craft the checkra1n desktop application to work with the the USB stack. The first USB stack they targeted as macOS, likely due to the developers familiarity with it. You can read more about the exploit in @qwertyoruiop talk at POC2019 which I attended.

So here's the work around. A disk image you can flash to any 16/32GB USB flash drive to boot into which will provide the macOS Virtual Machine and provide USB passthrough.

This is possible and I can get this working. Just give me another few days. You'll just need a 16/32GB USB drive and to boot into a live linux distro, run a script, and then you'll have a macOS Virtual Machine is USB passthrough for use with checkra1n. VirtualBox and VMWare WILL NOT WORK for checkra1n. You need to have lower level access.

About VM's and how this would work:

Stay tuned. I'll have an update soon. You can watch my YouTube video linked above.
