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

Hi all,

Glad to know I'm not the only person with this problem. I upgraded to the latest iTunes on my 2006 iMac (Intel) which has Snow Leopard 10.6.8. My iPhone 4 (original, 2010) will connect but won't sync or back up. It only shows 'other' as the content on the phone, doesn't differentiate between pictures, movies etc.

Really annoying, if I'd had any idea I wouldn't have upgraded. Any solutions yet? Is there a quick and easy way online to notify Apple?

Thanks a lot to cwa2. Worked perfectly. Back to 11.3.1

Thanks cwa2, worked well, i didnt have 11.3.1 but 11.2.2 and it still worked, everything seems back to normal

Wow. Impressive work. Thank you. Your solution worked for me as well.

However, before manually removing the files you listed I tried running the 11.3.1 installer with the "-allow" switch thinking it will force install the older packages over the newer ones. I didn't get any error messages but I still couldn't sync my phone.

So I proceeded deleting the files you mentioned and ran the 11.3.1 installer. And this time, sync works!

Thanks again! 🙂

Use the "Go to" from finder (shift+ cmd+ G) : type /System/Library/CoreServices/CoreTypes.bundle/Contents/Library/

cwa2: Deleted the files you mentioned in your Sept 13, 2014 10:50 PM message, re-installed 11.3.1 (which seems to be getting harder to find) and all is well again. Thanks for the second message spelling out what had to be zapped!

Hi there,

Any chance you can post easy-to-use instructions for those of us that aren't very tech-minded, please? Also, does anyone know where I can get a download file for 11.3.1?

Thanks.

Hi again,

Turns out, your instructions were easier than I'd though. I used the command + shift + G in Finder to find all of those files, removed them. If anyone needs 11.3.1, you can download it from here:

I won't be upgrading my iTunes again anytime soon. Thanks for your help, most appreciated.

I'm having the same issue. I'm not spending my Sunday night deleting files and reinstalling an old version of iTunes. Apple better fix this with an update and quickly...

You don't need Pacifist to view the contents of CoreTypes.bundle; in the Finder, just CTRL-click the bundle icon and select "Show Package Contents" to get to the file you need to delete.

Much thanks to cwa2 for the fix!

I noticed a bunch of you early on upthread posted that you have older machines.

I think I know why things broke for you guys:

The previous line is from when I still had iTunes 11.3.1 installed. The following line is from my first backup after installing iTunes 11.4.

Unless Apple's iTunes 11.4 installer is really smart and can cherry-pick which version of the binary inside the kext to install, it looks like Apple goofed and the installer only comes with a 64-bit version of the kext. Oops!

@cwa2: You rock, man ! You saved my life (hum).

Did exactly what you wrote and I'm now able to sync again !

You deserve huge kudos !

I upgraded to iTunes 11.4 a day or two ago, and now I'm not able to sync my iPhone 4. When I click on the sync button nothing happens. The horizontal bar (near the bottom of the window) has a wide stretch that says "Other". I'm running Snow Leopard (10.6.8) on a 2006 iMac Intel Core Duo with 2 GB memory. I haven't tried deleting all the files (from 11.4) mentioned in an earlier message. I'm hoping Apple will issue a fix soon so that I won't have to remove all the 11.4 files. Luckily I still have a copy of the 11.3.1 installer file.
