Hacker Nick Chan shared steps to upgrade unsupported iPad (6th generation) to iPadOS 18 via GitHub.
The process is complicated and involves a series of Terminal commands.
Drawbacks include it being a tethered process, Lightning and VGA adapters not working, wasted storage space, and limitations on Camera app and settings feature.
The motivation behind attempting this upgrade is to potentially jailbreak the iPad (6th generation) on iPadOS 18, making it the second-supported iPad for such an action.
