When I connect my iPhone 3GS to my computer, iTunes does not detect it. The phone displays the green battery meter indicating it's charging, System Profiler detects an "iPhone" connected to the USB bus, and I can even open iPhoto and pull some pictures off of it.

It doesn't appear under "Devices" in iTunes at all, nor does it appear in the Organizer window in Xcode.

I've tried:

  • Using a different sync cable.
  • Using a different USB port.
  • Restarting the phone.
  • Restarting the computer.
  • Connecting the phone to a different computer.

(I'm on OS X 10.6.6 and iTunes 10.1.2)

    If you start iTunes manually, does the iPhone get detected? Give a try on another computer (PC/Mac)... – Nivas Feb 23 '11 at 5:45
  • Does the iPhone show up on iTunes when you connect it to someone else's computer? – gesher Feb 23 '11 at 7:46
  • Nope. :( I updated the question. – Brant Bobby Feb 23 '11 at 15:09
  • Curiously, the phone didn't show up on my other computer either until I reinstalled iTunes there as well. – Brant Bobby Feb 23 '11 at 15:33

Run Activity Monitor (Applications/Utilities); do you see the iTunes Helper service running? Make sure you set the view to "All processes", not "My Processes". If it's not running, that's your problem. Re-install iTunes and away you go.

  • Yes, iTunesHelper is running. – Brant Bobby Feb 23 '11 at 4:18
  • @Brant Bobby - Now, that's interesting. Have you re-installed iTunes anyway? Anything showing up in the console logs? Have you tried a different computer? – Harv Feb 23 '11 at 4:33
  • Nothing shows up in the console logs when I connect the phone or start iTunes, no. – Brant Bobby Feb 23 '11 at 15:14
  • Reinstalling iTunes fixed the problem! Now it syncs and appears in Xcode again. – Brant Bobby Feb 23 '11 at 15:23

I had this problem on Lion, which doesn't allow the deletion of iTunes through the UI. Therefore, it was necessary to force the uninstall of iTunes from Terminal:

  • cd /Applications
  • sudo rm -r iTunes.app

I then pulled down the latest iTunes installer from Apple.

All my iTunes settings were maintained and my iPhone and iPad showed up again under devices.

This worked for me on my Mac:

  1. Connect the iPhone, iPad, or iPod touch.
  2. Open Image Capture (located in Applications).
  3. Select your device from the Devices list.
  4. Select "iTunes" in the pop-up menu in the Device Settings.

Sometimes iPhoto recognizes the iPhone and overrides iTunes. Not sure why Image Capture is the middle-man, but something to do with recognizing the iPhone as a camera rather than a phone, I'm guessing. This is a simple fix!

  • My iPhone stopped being recognised in iTunes after I installed Lion. This set of steps causes iTunes to load when I connect the iPhone to the Mac now, but the phone is still not being recognised in iTunes. – Bill Oct 12 '11 at 11:49

The other answers to this question as of writing this answer are now somewhat outdated – you can't manually uninstall iTunes without disabling SIP on El Capitan and newer macOS versions, and I would not recommend disabling SIP to delete iTunes. Continue reading this answer for an updated method.

Reinstall iTunes

If your iPhone isn't showing up on iTunes on macOS, you may reinstall iTunes by downloading the installer from here. Note that this will work on newer macOS versions such as El Capitan, Sierra, and High Sierra. You do not need to disable System Integrity Protection to do this.

As a matter of fact, this is what solved my issue on a Mac with High Sierra. My iPhone wasn't showing up in iTunes or Xcode, but reinstalling iTunes allowed it to show up again.

If, however, you issue isn't solved by reinstalling iTunes, there are a myriad of things you could try. In order to diagnose my own issue I made a list of things you could try, which you can find below. Some of these points may solve your issue. Some allow you to diagnose what might be causing the issue; these will thereby help you to isolate the cause and hopefully be able to fix it.


For macOS and Windows

  • Take a look at Apple's own guide for troubleshooting the issue (advice for both macOS and Windows is available here).
  • Try a different, certified lightning cable. A lightning cable might stop working (even if your device charges). Using an uncertified (non-MFi) cable can cause unexpected behavior such as preventing your iPhone from showing up in iTunes.
  • Try connecting your iPhone to a different computer. Connect it to another Mac; does it show up there? What about on a Windows PC? If it shows up on another computer, there might be something wrong with your own computer. Try looking at Apple's guide above if this is the case.
  • Try connecting another iPhone to your computer. Does it show up? If it does, there might be something wrong with your main iPhone. If it doesn't, it might mean that iTunes on your computer doesn't want to display any devices. You can confirm this by checking the previous point.
  • Try restarting iTunes. If that doesn't work, try restarting your iPhone or your computer. Perhaps it'll show up after a reboot.
  • Try different USB ports on your computer, in the case that one is faulty.
  • If you have any third-party iPhone managers installed such as AnyTrans, iMazing, or iFunBox, try seeing whether the device shows up there. You may also try other apps that work by detecting your iPhone and see if they can still detect it (such as coconutBattery).
  • Unlock your device and see if any computer trust popup shows up.
  • Is the iPhone or computer running on beta software? If so, that might be causing unexpected problems. Either upgrade to the latest beta or downgrade to the latest stable release (usually the latter will work).
  • Put your iPhone in DFU mode (if you have an iPhone 7, you need to see the special instructions on the bottom of that page). After putting it successfully in DFU mode, does it show up in iTunes? If it does, then your cable most likely works. If it doesn't, try plugging it in (while it's in DFU mode) into another computer, with another cable, or into a different USB port.
  • Reset your iPhone privacy settings, which resets computer trust settings. Warning: this is not guaranteed to solve the issue, and will cause all your privacy settings to be deleted. I recommend your open your essential apps (camera, GPS apps, communication apps, etc.) and allow permissions so that you don't have to deal with them later (I once reset my settings and the camera location popup didn't show up, which meant a lot of pictures weren't geotagged).

For macOS only

  • Open System information (located at /Applications/Utilities/System Information.app) and click the USB tab on the left. Does "iPhone" anywhere in the USB tree view? If it does, your Mac recognizes that an iPhone is connected to it, even if iTunes doesn't.
  • Open the Image Capture (located at /Applications/Image Capture.app). Does it recognize your device?
  • If you have Xcode installed, try seeing if your device is recognized by it.

For Windows only

  • Does your iPhone show up as a device in Device manager?
  • The best advice I would suggest on Windows would be to follow Apple's guide on troubleshooting this issue on Windows which I linked above.
  • If nothing seems to work, try reinstalling iTunes.

Even if these suggestions don't help you fix your problem, they'll give you an idea about what's causing the problem. Is it your device, your cable, or your computer? What about these may the problem be? Hopefully with the new information you'll be able to come to a better informed decision as to how to go about fixing the problem.

  • Update: I updated my mac OS from 10.12.6 to 10.13.6. This problem showed up with no notices for required software update. Downloaded iTunes from apple and re-installed over existing. Got a message that I needed a software patch or update. Accepted the update (took about 2 minutes). Re opened iTunes and it works now. – Mephistopheles Oct 25 '18 at 17:01

this worked for me.

I managed to fix this problem by opening the device manager and plugging in the device. the computer recognized the hardware but said there was a problem with the driver then I went to > Universal serial bus controllers > apple mobile device USB driver > update drivers. It worked!!!

    This is a problem on OS X and it looks like you are drawing a parallel to Windows. Could you elaborate? – bmike Nov 13 '12 at 22:52
