I connect my iPhone to the new version of iTunes on my iMac and it instantly freezes. I get the beachball forever and I have to force quit it. If I remove the iPhone, iTunes starts up normally. I tried restoring the old verison via Time Machine and reinstalling but then software update tells me I have the latest version 7.6 so it won't let me reinstall 7.7. I have 7.7 resinstalled via Time Machine once again with the spinning beach ball. Any help? On my MBP it works perfectly.
