Q: Upgraded to iTunes 11.4 and now it won't sync my iPhone 5s-sync button is greyed out.

This works as long as you don't need to connect an iPhone 6 or 6 Plus. You'll get a message bout the device requiring a newer version of iTunes if you do, and will have to do the steps to install 11.4 and then revert to older copies of several files.

I'm stuck with both my 4-year-old iPhone and my 2006 MBP anyway, so like I said, I solved MY problem. May not work for everyone. Now, if I win at the lottery and decide to buy an iPhone 6, I may have to reconsider my euphoric statement...

hey guys just opened a case with apple and showed them this thread. Hopefully theyll send it up their engineers and come out with a real fix...

I also opened up a case with Apple support yesterday along with 6plus55

Everyone reading this and affected by this issue needs  to do the same, Apple needs to pay attention to this issue.

Thanks CWA2 worked perfectly.

just remember that when you do, you mention that this is a 32 bit mac issue. i told them im worried apple wont addess our old computers...

I don't think so,  6plus55    I'm using a mid 2011 Mac 27 inch running OS 10.8.5 with an iPod touch fifth-generation.

I'm not sure but I do think my mac is a 64 bit. Please correct me if I'm wrong.

you have the greyed out button with the yellow "other" bar on the bottom too? have you tried any the fixes here? from what i understand its because of the kext not being written for 32 bit macs, which is whats causing the issue. the airTrafficHost seems to be the other problem. however with both of these installed, my phone will start syncing but not actually sync if that makes sense. it just endlessly hangs on the final step of syncing "waiting for changes to be made".

I assume you are talking to me...

This is what I posted on my issue at Re: System extension cannot be used

I was planning on going to the latest version of iTunes so I can up load IOS 8 on my iPod...

I went back to see it if could be uploaded again and the new version seems to be uploaded it said I have 11.4…but will it work right and can I get the new IOS 8 with this issue what ever it is?

No clue what this is and how to fix it any help on this?

Since I did not download IOS 8 on my  iPod touch fifth-generation, it still works okay. But I still have iTunes 11.4...

So I assume that if I would go to iOS 8 on my iPod touch fifth-generation (which I will not at this time), I would have all the issues everyone else has  even if it's not an iPhone.

So I'm guessing mine is the same issue with a different twist to it.   The good news is my iPod touch works fine...the bad news is I can't get iOS 8.

Big UP to cwa2!

Without such people, as well as others who have added helpful explanations and support, I for one would be lost! As it is, I managed to get sync back.

Big DOWN to Apple! Yes, you're probably trying to force obsolescence on those of us with older machines, although benefit of the doubt says you didn't think through enough/do enough testing; ether way SHAME on you!

Hello CWA2

Thank you for your Help This work perfectly

I am with MACBOOK PRO Snow Leopard 10.6.8

First intel Macintosh 2.16Ghz Intel Core Duo.

and i have tried everything that people have said and that is the first time everything works perfectly

Thank you

Thanks for your suggestion. 

I tried following the procedure, but, in my case, the "reorganize files" option was greyed out so I was not able to proceed further.

Ok, I followed all the instructions and the sync button was available again but still showing me as over capacity.

I plugged my phone into my work laptop which has iTunes 11.3 for windows and this was showing as over capacity so thinking it was something related to the ios 8 upgrade too I downloaded iTools and renamed the iTunes database file to .old then rebooted the phone.

When I went to resync tonight from my mac all was well again.

I'm now happy syncing my iPhones 4s on iOS 8 using My Intel Core Duo iMac running 10.6.8

Thanks for everyone who has helped.

Come on Apple...lets get this fixed in 11.5 / 8.1

Thank you! It worked!

my itunes 11.3.1 was working/syning fine, and then i installed itunes 11.4 and have the same problems as everyone else

my computer is a 2006 macbook pro 32-bit running 10.6.8

so, i had a question in regard to  cwa2's fix of the problem (or anyone else who might know)

i tried to follow the steps, but when i get as far as :

" /System/Library/CoreServices/CoreTypes.bundle/Contents/Library/MobileDevices.bu ndle "

its not ALL there, or more specifically....

" /System/Library/CoreServices/CoreTypes.bundle " is there

but the trail ends there, there is no " /Contents/Library/MobileDevices.bundle "

should i remove the whole bundle?

i.e. remove "/System/Library/CoreServices/CoreTypes.bundle " ?

because the other part, the " Contents/Library/MobileDevices.bundle " is missing !

thanks!
