iTunes cannot sync... apps installed on the iPhone could not be determined.

This solution worked for me as well. Thanks!

So simple....thanks. **** hub!

I fixed the problem of the undetermined apps, but now the iPad hangs up on the last step whhere it is syncing tones and waiting for items to copy. Both the ipad and itunes have the same number of tones, so I dont know why it hangs on syncing tones. And I havent changed any of the tones in either place for several months.

Sir, can u please tell me how to go into the finder? i cant understand that process. so, please let me how to do by step by step like video tutorial or like showing pics or something. Thank u

I am having this exact issue sunargon. I have called Apple Support four times, spent two hours on the phone Wednesday night with a senior rep, countless HOURS reading threads, all to no avail yet.

I ALWAYS keep itunes, apps and devices updated to the latest version. I am running Windows 7. I recently moved my library from an aging laptop to a desktop unit, the move went well. My music syncs, my iPhone updates download and sync, my purchases transfer from the device to iTunes, apps requiring updates are recognized and download to iTunes. iTunes sees my devices and contents correctly, 'remove', 'install' and 'update', through iTunes are showing correctly - but still the backups and syncs do not work as they did before. Futhermore, they give me no indication that they are not creating backups or downloading updates. The senior rep tried everything, checking date and time on my computer, uninstalling all apple programs and reinstalling, unauthorizing, reauthorizing, etc. We ran diagnostics twice and I uploaded files to apple for the engineers to take a look. They are supposed to call me next week.

I have had iPhones since 2008 and have NEVER had an issue. I typically purchase apps through the store on my devices, then transfer purchases to iTunes when I connec the device. I download app updates to itunes, then sync my devices. I have two iPhone 5's and an iPad2. NONE of my devices are backing up or syncing. They go through the motions and give me ZERO errors but the sync is not happening. I am able to backup my devices by pressing 'backup now', and it works, but does not do so as it did before.

When any of the three devices is plugged in iTunes sees the apps and sees which ones need to be updated, but the updates will not transfer. I asked the senior rep if I should wipe the phone and reinstall from backup and he told me not to, he said the issue is something other than any of the devices or iTunes . . . more to come when I find a solution.

Finder is the MAC version of Windows Explorer

Hi Alex,

I am a Window's 7 user and am having this issue you are so kindly helping people fix. You can read my symptoms in my post from earlier (a few prior to this one). I know you are a MAC user (wish I was) so Windows instructions may be a challenge for you. Can you explain the essence of the steps. What files should we be moving / deleting - I am sure that they are named the same in Windows, so I am hoping I could figure it out if you could explain the goal of the steps.

I spent 2 hours with an Apple Senior Rep the other day and we uninstalled all of the Apple software (in the correct order), then reinstalled iTunes to no avail. We deleted an iTunes SL file of some sort, but did nothing with the library files. I have read your posts several times and I can discern that you are doing something with the Library file(s), just not sure what.

Thank you for your assistance, looks like you have helped lots of folks, I am hoping I will be one of them!

Restarting itunes 11, after having done many of the steps above seemed to have worked. All the apps are finisnghing their updates and the backup is complete.

Thanks.

Jeff

Thanks @alexfrompittsburgh this solved my issue too.

My sync hangs out on waitin for changes to be applied i did everything and nothin seems to work

I have a similar issue. all the apps are on my phone and in a mess. I want to organise them

In the past I have sorted them in 'apps' on the itunes iphone

then 'sync' organises them on my phone

now since the latest IOS it isnt working 😟

please help

That seems to have gone away. Don't know why.

I have found that most times if I ignore the message and sync again, the problem seems to go away for a while.

I'm almost embarrased that this simple fix worked, but all i did was update all my apps on the phone. Unplug, shut down and re-start itunes. Worked fine.

nothing is working for me, and apple don't seem to have any staff on here answering questions. It is a big inconvenience to go into their store, and I'd have to take my laptop in too since it has itunes :/

is anyone able to help me?
