New iPhone 5s purchased last Thursday & can't get it to sync with late 2011 iMac (10.6.8) Tried disconnecting the supplied Thunderbolt->USB cable and tried all the different USB ports on the iMac with no luck. Cable works to charge the phone so I assume it's ok. iTunes doesn't automatically open up and when i DO open it manually, no mention is made of a connected iPhone. iPhone Settings->Bluetooth IS set to "On." iPhone, once connected says "Trust this computer?" and I hit trust. I went to the Bluetooth System Preferences and started through the proceedure. iMac detects the iPhone but says "iPhone NOT connected" with "On" and "discoverable" blocks checked. I click "setup Bluetooth device" and iMac shows searching for bluetooth devices. Takes about 1 minute for "iPhone - Smartphone" to show up. I click "continue" & "Attempting to pair with iPhone" then the sync code being sent to my iPhone. Phone shows same code and asks if I want to continue. Press continue - wait a few seconds - phone responds "Bluetooth pairing request" with same code and I hit "Pair" but seconds later (maybe 1-2) "Pairing unsuccessful" is displayed. Anyone tell an old guy what I'm doing wrong?
