HI, my sister has just received a new iphone 6s, and we are trying to do a sync/back up from itunes (does not want to use iCloud). But it has been a long time since her laptop has been updated, currently running on OS X 10.6.8.
I have tried to download El Capitan but it takes over an hour to download and then on the last stretch it clunks out and says an internet connection problem, which is impossible (connected to ethernet cable and wifi connection). I dont really know too much about apple, but can anyone shed insight into why this keeps happening? Any suggestions to avoid it? Tried everything i knowabout 6 times and each time has failed. PLEASE HALPPP
