Okay, long story short, I got iTunes error 3194 and I'm attempting to fix it through Terminal, editing the hosts file in /private/etc. When opening the file in Terminal, there are a few lines of code missing from the display, which are shown in the Apple Support Forums/Communities. The lines in question are: fe80::1%lo0 local host # 18.104.22.168 gs.apple.com I was tempted to add them myself, but being not that good with code I didn't want to take any risks. Is it okay to add these lines, or is there something more sensible I can do to fix this? I'm running OS X Yosemite 10.10.4 on the 13" MacBook Pro 2012 model. If there is another way to work around error 3194, PLEASE let me know!
