I have an ATV2 running 5.2.1 TETHERED JB and just saw the news about 5.3 untethered JB and I’m of course quite interested in this upgrade. I’m using a MacBook Pro running Mavericks.
I haven’t managed to upgrade though. I try to follow to the guide, but when it tells me to connect my ATV2 and I connect it, it tells me it couldn’t find any connected ATV2
What am I doing wrong?
