I couldn’t find a post that related to my problem. I set up my Apple TV 2 with the tethered boot on my Macbook Pro. All works well and using the tethered boot on my Macbook Pro it starts flawlessly. However, I tried to tether boot the Apple TV 2 using the same program (i copy pasted from my pro) on my Macbook Air and the screen on the Air shows that it found the device in DFU mode and stays at the candy cane forever.
Trying to fix the situation myself I thought that the tethered boot must use files from the created ipsw file. So… I copied the same ipsw file from my pro and put it under the same directory of my air and tried it again. Only to be greated with a “failed to boot” message. This did get passed the waiting for dfu screen but still no boot.
How do I get it to be able to tether boot using a different computer then the Pro which I set it up on?
