I've just upgraded my Mac to Lion, and now my iPhone is not being recognised in iTunes.

I've tried...

  • Updating iTunes (to 10.5)
  • Checking for all updates
  • Restarting both the Mac and iPhone
  • Extracting iTunesHelper.app from the iTunes bundle and installing it into the Login Items list, and confirmed it's running in the Activity Monitor.

For the past 3 years I've been happy with the "It just works" idea, but not today. :(

What other options are there?

  • Does the phone's screen light up when you connect it? Does it charge when connected to the computer? Have you tried another cable? – Jan Henckens Oct 12 '11 at 12:28
  • @Jannemans - Yes the phone lights up and charges ok. – Bill Oct 12 '11 at 12:35

    SOLVED: Out of desperation I downloaded and installed iTunes a second time, and now the phone is detected! Don't understand why the first update to 10.5 didn't do the trick. – Bill Oct 12 '11 at 12:36
  • @Bill you should mark your question as answered since the problem is resolved :-) – Ermiar Jun 16 '12 at 16:29

Start by checking in the system profiler under USB to see if the Mac see's that the iPhone is connected. .

System Profiler

Then remove the following to the Trash and RESTART the computer

/System/Library/Extensions and Locate the file AppleMobileDevice.kext

  • Thanks for the suggestions. Unfortunately, I wasn't able to try these, as I found a second install of iTunes ended up solving the problem. It will be handy having this post here for the future though, in case I encounter the problem again. – Bill Oct 12 '11 at 12:38
