Seas0nPass for Mac
Seas0nPass is a minimalist Mac OS X application that can help you jailbreak your Apple TV device. The application offers support for the Apple TV 5.3 firmware version and creates an un-tethered firmware version.
Make sure to follow all preparatory steps before trying to jailbreak your Apple TV device
Besides the Seas0nPass application, to go through the jailbreak procedure successfully you must have the latest iTunes version installed, a micro USB cable, and to make sure that no other Apple devices, such as iPhone, iPads, or iPods are connected to your computer.
To get started, press the Seas0nPass "Create IPSW" button and connect the Apple TV device to your Mac via USB, while leaving the power cord unplugged. The utility will start downloading the latest Apple TV firmware and integrate the credentials for creating a jailbroken version.
Effortlessly install the jailbroken firmware version on your Apple TV device
The next step is to put your Apple TV device into DFU mode by pressing the Menu and Play buttons on your Apple TV remote when the device’s front led starts to flash rapidly. If everything goes well, the Seas0nPass app will install the jailbroken firmware version without further user interaction.
However, you can also use the Seas0nPass application to boot your Apple TV in tethered mode: press the “Boot Tethered” button, connect the Apple TV via USB, and as soon as the front light starts flashing, also connect the power cable.
To complete the process you must press the Menu and Play buttons on the Apple TV remote, and after the Seas0nPass announces you that the boot has completed, you must remove the USB connection and plug-in the HDMI cable.
Follow the developers instructions to jailbreak your Apple TV device
To conclude, Seas0nPass offers you the possibility to install a jailbroken firmware version on your Apple TV, and provides support for booting in tethered mode, but you need to follow precise instructions.
