iTunes cannot sync apps to the iPhone “iPhone” because the apps installed on the iPhone could not be determined.

did it work the second time you tried to sync? i have updated apps and switched off phone and imac and it works once but if i try and sync again it does the sames thing and wont sync due apps not being determined!!!

iphone 4s mac osx lion

I haven't tried to sync again as I just did this the other day but I imagine you should double check all your apps are still up to date.. I've already had to update a few again

This solution (removing and cleaning the SIM card) worked for me.

yeah same here. i think it's the new ios on the computer, becuase i can still sync to my older macbook, but just got a new one and it gives me this message. i know i am up to date on everything so something is up.

ps: the maps on the iphone still suck lol. can't use public transportation anymore? ***?!

This worked for me: I unplugged the phone. Rebooted my Mac. Restarted the iPhone. When I restarted iTunes and plugged my phone in, everything worked again.

To restart iPhone, first turn iPhone off by pressing and holding the Sleep/Wake button until a red slider appears. Slide your finger across the slider and iPhone will turn off after a few moments.

Next, turn iPhone on by pressing and holding the Sleep/Wake button until the Apple logo appears.

Fantastic. This solution worked for me. Many thanks.

please tell me you didnt just post instructions how to turn off then turn on an iphone?

six hours ive just wasted on this problem, im struggling to understand how im now getting this in 2013!!!!!!!!

using latest version of everything

(normally i say something bad against apple but they delete my comment, strange that they only delete my comment when i say something negative against apple though)
