Hi out there,
I'm using an iPhone 3GS and updated my iPhone OS to 4.0 and then to 4.0.1.
Due to some software problems (not in connection with iPhone or iTunes) I had to reinstall Mac OS X SL "Basic" and "Essential" software packages. Having done this, I applied Mac OS X 10.6.3 combo update and iTunes 9.2 update. And since then iTunes won't recognize my iPhone.
So I did a complete delete of iTunes as told in the documents of the Apple knowledge base and then installed iTunes 9.2 again. And after this reinstall my iPhone was regognized.
But after the next system restart the same again: No recognition of my iPhone. So I tried a new reinstall of iTunes (without prior deletion) with the result that my iPhone was recognized. But only 'til the next system start...
I've done this for approximately five times, but I think this couldn't be the intention of the iTunes programmers...
Does someone have an idiea?

    If you have snow leopard and it doesn't recognize your iphone try doing the software update then reboot your computer. When I upgraded to snow leopard, I had a software update that said one of the fixes was a problem with snow leopard recognizing iphones in itunes. Hope that helps

    I tried a full clean install of iTunes. For that I opened the installations package with Pacifist and then removed each software component shown in Pacifist BY HAND from my system (even the private frameworks...).
    After that I restarted my MacBook Pro, emptied the Trash and reinstalled iTunes.
    Then I MANUALLY added iTunesHelper to the startup items in the user preferences pane and rebooted. Now I got everything to use my iPhone via iTunes (iTunesHelper is running - I checked it with activity monitor).
    But my iPhone is still not recognised by iTunes whereas my iPod nano (3rd generation) is recognized.
    Does anyone has an idea? May be APPLE SUPPORT has a solution?

    Thanks for help and greetings from Germany

    Hi out there,
    I encountered another problem:
    When installing iTunes there is no startup item "iTunesHelper" added to my profile (I checked in PrefPane "Users")so that it is started during next reboot.
    And there is no installation receipt created in the "/Library/Receipts" folder.
    I still have to reinstall the iTunes package to sync with my iPhone...

    Try this. It worked for me. I apologise for lifting it from another thread.

    Try reinstalling the AMDS, but do so in the following order:

    1. Disconnect your iPhone from your Mac.
    2. In the Finder, locate iTunes in the Applications folder and drag it to the Trash.
    3. Move the iTunes icon to the Trash.
    4. Choose Go > Go to Folder.
    5. Enter /System/Library/Extensions and click Go.
    6. Locate the file AppleMobileDevice.kext and drag it to the Trash.
    7. Choose Go > Go to Folder.
    8. Enter /Library/Receipts/ and click Go.
    9. Locate the file AppleMobileDeviceSupport.pkg and drag it to the Trash. If prompted, authenticate with the administrator password.
    Note: This file may not be present in Mac OS X v10.6 and later; skip to the next step if this is the case.
    10. Restart the computer.
    11. Choose Finder > Empty Trash and restart the computer.
    12. Download and install the current version of iTunes.
    13. Connect your iphone to your Mac again and open iTunes.

    Hi, etz1!
    The support document you copied, didn't help. I did as told there but without success. So I reinstalled my system as followes:
    - Booting from installation DVD
    - Chose my MacOS X hard disk as installation volume
    - Selected the installation options
    - Installed the software
    - Applied all available updates
    But even with this tactic I haven't been successful.
    The strange thing is that my iPhone is recognized by iPhoto...
    And it's getting more strange that there is no synchronization even the iPhone is recognized after reinstalling iTunes and selecting the sync options.
    In the moment the behaviour of my system is not really satisfying...

    For general information:
    there is an update available via systems "Software Update" called "iPhone SDK-Compatibility Update" (size: 6 kByte).
    after install and restart iTunes recognized my iPhone. But my second problem (no further sync) was not solved...

    I have the exact same problem you're having, so you're not alone!

    iPhone 3G + iOS4.0.1 + OS10.6.4 + iTunes 9.2.1

    If I re-install iTunes the iphone appears again and I can sync. But after a few days the problem returns. Really crazy and REALLY annoying.
  • Ansgar Hoeber Level 1 (120 points)
    Hi Scott F,
    I don't know if the "iPhone SDK-Compatibility Update" works with the iPhone 3G.
    I'm using an iPhone 3GS, iOS 4.0.2 and MacOS 10.6.4.
    And the "not synching" problem was just located "between the user's ears" :
    You have to check those items you want to sync again in the iTunes "Infos" tab after reinstalling iTunes.

    Thanks so much for the reply Ansgar. The SDK update seems to have fixed it ... finally! I went and ran Software Update and there was the SDK Compatibility Update waiting to be installed. Strange, because I had never installed a previous version of it.

    However, your comment about the problem being between the "user's ears" wasn't accurate! . I found MANY people online with this same problem we had. It has nothing to do with selecting the items to sync in the tabs. You can't select anything if your iPhone doesn't appear in iTunes, as you know.... and it wasn't appearing because of this bug. Every time I would re-install iTunes the iPhone would reappear again and that would last for a day or so. Then the problem would come back.

    So far it looks like the SDK update has solved it.... let's see if it lasts!

    Thanks again for advising about this. I posted in several forums around the web and found no answers!

    Bingo! That solved my problem. It was just a small update, downloaded in a couple of seconds, installed, rebooted, everything is good now.
