I don't doubt that it is possible to JB the ATV2 with a Mac as gazpilot and others have proven, but there does seem to be a higher success rate among those who have used the PC version of GreenPois0n, in the end I got so fed up with the JB failing and GreenPois0n crashing on my iMac that I felt the only option was to use a PC, which worked![]()
Going the PC route worked for me too. I should have gone that route about 30 tries ago when I was trying with my MBP.
