pongoOS 2.4.5 is now available at https://github.com/checkra1n/pongoOS.
pongoOS 2.4.5 open-sources the SEP exploit, making that part fully open-source for the very first time. This makes the Secure Enclave processor accessible to a much wider public than before on Apple A10 devices and earlier.
The kernel patchfinder is also open-source in this release.
Boot-to-Linux support (for Project Sandcastle) is restored.
The full open-sourcing of the checkra1n project as a whole will happen as soon as the Windows version is ready, stay tuned.
Happy new year!
