MacOS Big Sur is the 17th release of the Mac operating system for Macintosh computers and is the successor to macOS Catalina.

We need to write a kernel driver to support Windows which will take time. Q: When is Windows support coming? A: Soon™. But PongoOS, the kernel patchfinder and the SEP exploit are already open source on GitHub. We had hoped to get there in 2020, but we didn't manage to. We will release the full checkra1n source once we have a Windows GUI version. A: checkra1n is released in binary form only at this stage. Q: Where are the sources? I want to write a dark-mode theme and publish the jailbreak as my own. If anyone asks for donations, it's a scam. Q: I love the project! Can I donate? A: Thanks, we love it too! The project does not currently take any donations. You can expose it on your local machine using iproxy via USB. Q: Can I ssh into my device? A: Yes! An SSH server is deployed on port 44 on localhost only. Can checkra1n decrypt my data or get access to a locked device? A: No. A: Please check here and follow the bug report template. Q: I have a problem or issue to report and I don't think it's related to a bad tweak. If the issue goes away, a bad tweak is very likely the culprit, and you should contact the tweak developers. If you suspect a recently installed tweak, you may attempt to enter no-substrate mode by holding vol-up during boot (starting with Apple logo until boot completes). Remember many tweaks never saw iOS 13 in the pre-checkra1n era. A: Many problems and bootloops can be caused by buggy or incompatible tweaks. Q: I have a problem or issue to report after jailbreaking. We do recommend you backup your device before running checkra1n. However, as with any software, bugs can happen and *no warranty is provided*. Q: Is it safe to jailbreak? Can it harm my device / wipe my data? A: We believe jailbreaking is safe and take precautions to avoid data loss. Q: Ugh, I don't like GUI? A: Ok, you can use './checkra1n.app/Contents/MacOS/checkra1n -c' from the console, or download a Linux CLI build. If you reboot the device without checkra1n, it will revert to stock iOS, and you will not be able to use any 3rd party software installed until you enter DFU and checkra1n the device again. Hax happens auto-magically from that point and the device will boot into jailbroken mode. Q: How do I use it? A: Open the checkra1n app, and follow the instructions to put your device into DFU mode. Q: Why was the beta release delayed? A: We didn't want the release quality to end up like iOS 13.2, you deserve better. Q: What is checkra1n? A: checkra1n is a community project to provide a high-quality semi-tethered jailbreak to all, based on the ‘checkm8’ bootrom exploit. Support for other package managers, including Zebra and Installer is coming soon and is expected within the coming weeks. Package managersĪt the moment, checkra1n only supports installing Cydia. Work is ongoing to support Windows, which will be added in a later release. This beta is only available for macOS and Linux. It is unknown whether any other language is affected. Some users have reported checkra1n crashing when Chinese is set as the only system language.If you disconnect the cable, then as soon as macOS boots it’ll take over the USB connection and disallow communication with the T2.Linux GUI build when using CLI mode doesn’t support auto assertion of DFU mode on advanced Apple TV 4K breakout boards.The exploit may not work as reliably on some devices, such as the Raspberry Pi Zero and Raspberry Pi 3.A7 devices will currently not work with the Linux version.A11 devices on iOS 14.0 and above require removing the passcode and enabling “Skip A11 BPR check” in the options.Fix package dependency issues on the deb repo.Hotfix for A9X devices, which could not boot on 14.5 at all with 0.12.3.This release is a beta preview and as such should not be installed on a primary device What’s new Bug fixes
