Checkra1n Jailbreak Update Adds iOS 14.5 Support, Bug Fixes Posted by Rajesh Pandey on Apr 30, 2021 in Checkra1n Jailbreak, News Checkra1n v0.12.3 has been released to the public with support for iOS 14.5 on compatible iPhones along with support for M1 Macs. The release also fixes a bunch of issues with Checkra1n that should lead to a more stable jailbreak experience. While the update adds support for M1 Mac, Windows support is still missing. This was promised long back when Checkra1n was first released, but so far, the team has not released a Windows version of their jailbreak tool.
