My iPod will no longer sync after I upgraded.
My iPod will no longer sync after I upgraded to Snow Leopard yesterday - August 26, 2015. I own a MacBook 5,2 and it is running 10.6.3. The iPod still charges fine, but the icon does not appear in either iTunes or Finder. I tried updating to iTunes 12.2.2, but the upgrade failed - after following the directions and restarting my computer, I still have iTunes 10.6.3. I have connected and disconnected the iPod. I have started and stopped iTunes. I looked for a button to push to tell my iPod to "trust" this computer, but there is nothing like that showing up. I was told to push the menu button and home button simultaneously while loading iTunes, but I only have one button to push. I tried pushing that home button while starting up iTunes, but nothing happened. I tried pushing the home button and the little power button at the top while starting iTunes, but that did nothing. It didn't even power down the device. I have now followed all of the instructions I found on online Apple Support, and have no idea what to do next.
This is an iPod touch, generation 2, purchased in July of 2009. Please tell me what I need to do so that my computer will recognize and sync with my iPod. It may be old, but I use it daily in my education. Thank you.
