The Apple T2 security chip has finally been jailbroken! Here’s all you need to know about it. The latest update of checkra1n adds support for bridgeOS – the operating system that powers the Apple T2 security chip. For what it’s worth, the T2 chip is not A10 per se but it is derived from the Apple A10 Fusion architecture.
Since checkra1n is still in beta, there are a few issues you need to be aware of. Firstly, you might have to reconnect your device after jailbreaking for bootstrap upload.
Secondly, macOS takes over the USB connection and blocks communication after bootup.
If you are interested in jailbreaking the T2 chip, download checkra1n jailbreak v0.11 from this link.
