IOS 14.5 has been officially released for some time now, and Checkra1n jailbreak has been updated to the latest version v0.12.3, which supports iOS 14.5.
As mentioned earlier, the Checkra1n jailbreak has been updated to version 0.12.3 to support the newly released iOS 14.5, support for Apple's M1 Mac, and bug fixes.
New bug fixes improve the overall performance of the platform and allow for a seamless user experience. Please note that support for Windows is still missing, but will be added in a potential future update.
There are also some China-specific issues to watch out for, with some users reporting that Checkra1n crashes when Chinese is set as the only system language. It is not known if any other languages have been affected.
One thing to note is that the Checkra1n jailbreak tool for iOS 14.5 only works on selected iPhone and iPad models. On the iPhone side, you can use the update from iPhone 6s to iPhone X.
