## What it is
palera1n is an open-source jailbreak tool for Apple devices using the checkm8 bootrom exploit, supporting A8 through A11 chips and T2 security chips on iOS/iPadOS/tvOS 15.0 and bridgeOS 5.0 and higher. It is run from a Linux or macOS computer's terminal and offers rootless and rootful jailbreak environments with package managers like Sileo and Zebra.

## Use cases
- jailbreak an iPhone or iPad running iOS 15 or later
- jailbreak Apple TV HD or Apple TV 4K on tvOS 15+
- jailbreak a Mac with a T2 security chip
- customize an iOS device with tweaks via Sileo or Zebra
- get shell access to an iOS device with a binpack of CLI utilities
- choose between rootless and rootful jailbreak environments

## When to choose
- you have an A8-A11 or T2 device on iOS/iPadOS/tvOS 15.0+ or bridgeOS 5.0+
- you want an actively maintained, open-source checkm8-based jailbreak
- you need rootless or rootful jailbreak options with Sileo/Zebra support

## When to avoid
- your device is A12 or newer (e.g., iPhone XS and later)
- you are on iOS/iPadOS/tvOS versions below 15.0
- you cannot use a Linux or macOS computer with a USB-A cable
- you rely on your passcode and Face ID data on an A11 device, since the passcode must be disabled while jailbroken
