It gives users freedom to install and modify whatever they want on their devices, but it is achieved by exploiting vulnerabilities in Apple's code. Jailbreaking has long been a gray area because of this tension. It could allow hackers to install keyloggers or other malware that could later grab the decryption keys, or it could make it easier to brute-force them, but Checkra1n isn't a silver bullet. Finally, the jailbreak doesn't give an attacker instant access to a target's encrypted data.

To be certain that a Mac hasn't been compromised by the jailbreak, the T2 chip must be fully restored to Apple's defaults. The Checkra1n researchers do caution, though, that the T2 chip itself doesn't reboot every time the device does.
An attacker could jailbreak a target device and then disappear, but the compromise isn't "persistent" it ends when the T2 chip is rebooted. This means hackers can't remotely mass-infect every Mac that has a T2 chip. The tool can only run off of another device over USB. The first is that an attacker would need physical access to target devices in order to exploit them. There are a few important limitations of the jailbreak, though, that keep this from being a full-blown security crisis. "This chip, which was supposed to provide all this extra security, is now pretty much moot."

The vulnerability is unpatchable, because the flaw is in low-level, unchangeable code for hardware. Combined with another T2 vulnerability that was publicly disclosed in July by the Chinese security research and jailbreaking group Pangu Team, the jailbreak could also potentially be used to obtain FileVault encryption keys and to decrypt user data. The jailbreak could also be weaponized by malicious hackers, though, to disable macOS security features like System Integrity Protection and Secure Boot and install malware. It can even be used to run Linux on the T2 or play Doom on a MacBook Pro's Touch Bar. On Macs, the jailbreak allows researchers to probe the T2 chip and explore its security features. Now Checkra1n, the same group that developed the tool for iOS, has released support for T2 bypass. But the T2 also contains a vulnerability, known as Checkm8, that jailbreakers have already been exploiting in Apple's A5 through A11 (2011 to 2017) mobile chipsets. Apple added the chip as a trusted mechanism for securing high-value features like encrypted data storage, Touch ID, and Activation Lock, which works with Apple's "Find My" services. But the T2 chip, launched in 2017, created some limitations and mysteries. In general, the jailbreak community haven't paid as much attention to macOS and OS X as it has iOS, because they don't have the same restrictions and walled gardens that are built into Apple's mobile ecosystem. Worst of all, while Apple may be able to slow down potential hackers, the flaw is ultimately unfixable in every Mac that has a T2 inside. But the fact that the T2 chip is vulnerable in the same way creates a new host of potential threats. The flaw is one researchers have also been using for more than a year to jailbreak older models of iPhones. A recently released tool is letting anyone exploit an unusual Mac vulnerability to bypass Apple's trusted T2 security chip and gain deep system access.
