TS1591 My work iMac doesn't recognize my iPhone 4s.

My iPhone 4s works perfectly with my home iMac and but recently my iMac at work has stopped recognizing it. It doesn't show up in iPhoto, iTunes, nothing. Doesn't draw a charge when plugged in to my work computer, either. It was working fine up to the last few days. Same result no matter what USB port I use, and we've tested it with more than one cord. Also did a total software update with a full restart. Now running iTunes 10.6.3 with OS 10.7.4.

If the 2 computers have the correct cable connections, try the Target Disk Mode.

New imac doesn't recognize firewire 400

Just got the new imac and transferred all data from my old (non-intel) imac using a firewire 400-to-800 adapter.
Now, my new imac doesn't recognize my external (400 firewire) drives anymore. One of the drives has an USB which works with the new mac but transfers are very vey slow. The other drive has only firewire 400 and doesn't get recognized at all.
Any solutions?
Thanks.

Adapters can be troublesome, I'd recommend replacing with a Firewire 400 to 800 cable like this one. You can normally find these at your local computer store, Radio Shack or of course Amazon.

Can't burn data to a CD because iMac doesn't recognize CD has been inserted. Also, can't eject. What to do?

Can't burn data to a CD because iMac doesn't recognize that a CD has been inserted. Also, it won't let me eject the disk. How do I get my iMac to let me burn the data to the CD and eject the disk?
Finder currently has 2 "Untitled CD"s listed in it. One has been in there for months (without a CD inserted into the machine). I have tried several times unsuccessfully to remove the item from finder.

Please reset the SMC and PRAM 2-3 times each using the instructions in https://discussions.apple.com/docs/DOC-3603. Then attempt to eject. If that fails please use one of Kappy's ideas:
Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

My iTunes suddenly stopped working and doesn't recognize any of my devices and gives me a AMD error. I've tried several times to uninstall all Apple programs and reinstall to no avail. I'm running windows 7 on a Dell laptop. It worked fine for years .

My iTunes suddenly stopped working and doesn't recognize any of my devices and gives me a AMD error. I've tried several times to uninstall all Apple programs and reinstall to no avail. I'm running windows 7 on a Dell laptop. It worked fine for years then I decided to update my iPhone 4S and it didn't recognize it or any other iPod or iPad.
Can someone please help ?

I am having all sorts of problems with 9.1.1.Crashes and not only iTunes but I have to restart all the time.
GET TO WORK APPLE !!!!

The iMac doesn't recognize my external hard disk

My iMac doesn't recognize my external hard disk. The iMac also keeps a DVD inside. It doen't throw it out despite "eject".

Sounds like you might need to make that call. In the meantime here are a few of things you could try that may help:
To eject the disk try a restart holding down the mouse button - hopefully it'll eject.
If you are running either Mountain Lion (10.8) or Lion (10.7) try booting into the Recovery HD:
Restart holding down Command+r. At the screen with 4 choices choose Disk Utility and then select Macintosh HD and click on repair disk. If it fixes anything click on repair disk again until you get a clean pass. Restart as normal from the Apple menu.
If you are running an earlier OS you would normally carry out this process by putting the grey restore disk that came with your Mac in the Disk drive and restarting holding down the C key. Choose your language and at the next screen from the menu bar select Utilities>Disk Utility and then follow the above instructions (I realise you won't be able to do this if you have a disk stuck in the optical disk drive).
Try an SMC and PRAM reset: https://discussions.apple.com/docs/DOC-3603
Try a Safe Boot: Restart holding down the shift key until you see a grey progress bar. Once it's booted restart as normal from the Apple menu.
If none of this helps, I guess you need to make that call. Good luck.

My camera doesn't work + it doesn't recognize external cameras. what's the problem here?

I set up a new windows 7 version for my laptop (probook 4510s) & the camera doesn't work + it doesn't recognize any external camera. So how to fix my camera & get it back to work?

What kind of external camera is this? I am assuming it is a USB camera? Make sure that you aren't using any USB hubs. Also try connecting it to another USB port. Have you installed the drivers from the camera manufacturer yet?
Thanks,
Sean

My computer doesn't recognize my iphone and it shows up the apple and nothing is working. What can I do ?

My computer doesn't recognize my iphone and now my iphone displays the apple and I can't use it. What can I do ?

First, try to do a hard reset of your phone. (Hold down the Home button and the sleep/wake button at the same time for about 10 seconds. When the screen flashes and the Apple appears again, release the buttons.)
If that doesn't work, then you may have to put your phone in restore mode.
Power off your phone and disconnect it from the USB cable.
Close iTunes.
Then press and hold the Home button and while keeping the Home button pressed down, connect the phone to the USB cable.
Continue to hold the Home button pressed down.
After a few seconds, you should see the display prompt you to connect to iTunes.
After that, you should be able to restore your phone from iTunes.

My imac doesn't recognize my backup drive anymore,what can i do?

My Imac doesn't recognize my backup drive anymore,what can i do?

Unfortunately, that usually means the drive has died although it doesn't mean some other hardware failure or even software failure (in some cases.)
I think the wise thing to do is take it in for service.

ITunes 11.1 doesn't recognize my iPhone 4s with IOS 7 - phone is charging by iTunes doesn't see it. Any suggestions?

I upgraded my daughter's iMac to iTunes 11.1 and now it doesn't recognize her iPhone 4s. The phone will charge and DropBox see's it but iTunes doesn't. Any suggestions? I've already uninstalled and reinstalled the software so that doesn't work. Thanks for any help!

Hello jlgougeon,
Thanks for using Apple Support Communities.
For more information on this, take a look at:
iOS: Device not recognized in iTunes for Mac OS X
http://support.apple.com/kb/TS1591
Follow these steps to resolve your issue:
Ensure that your Mac meets the minimum system requirements for your iPhone, iPad, or iPod touch.
Install software updates on your Mac.
Note: If an iTunes update is available, apply the update.http://apple.com/itunes/download
Check USB connections. iOS devices require USB 2.0 to function properly. If you're not sure your Mac has USB 2.0 ports, refer to the computer's specifications.
Disconnect other USB devices and connect your device directly to a USB port on your Mac.
Restart your Mac.
Best of luck,

ITunes doesn't recognize my iPhone 4s

iTunes doesn't recognize my iPhone 4s.
Whenever I plug my iPhone into my computer it starts to charge like normal but iTunes does not recognize it. I've tried all of the troubleshooting steps provided by Apple (Downloading the latest iTunes version, reinstalling iTunes, updating the software on my phone, restarting my computer, etc). I've also looked at various tutorials on different websites that showed other methods. Among these methods were going into the control panel Device Manager or the Services program and taking certain steps within said programs. It seems I have tried everything under the sun to get iTunes to recognize my iPhone and so far nothing has worked. I have no idea what to do which is why I've resorted to this. Anybody know what might be going on? I'm running Windows 7 64 bit on my computer with the latest iTunes installed as previously stated. I've also just installed iOS 5.1.1 on my iPhone and this has not changed anything. If anyone has any idea what is going on and would like to tell me how to fix it, it would be much appreciated. Thanks.

If you've gone through this article and made sure the Apple Mobile device service is installed and running, you should look at the security software on your computer.
To make sure it isn't the security software, you can either follow the steps in the article below, or you could just uninstall it and test again. Then reinstall it again when you're done.
iTunes: Troubleshooting security software issues

I just installed update version 11.1.4.62. Now Itunes doesn't recognize my iphone or ipad. My wife just installed the same version with the same result. The problem is clearly a problem with itunes. What's wrong with itunes?

I was running the previous version of itunes and it worked perfectly. I just installed the latest version of itunes (version 11.1.4.62) and restarted the PC and now itunes doesn't recognize my iphone or my ipad. I'm running Windows 8.1 on my pc. I tried diagnostics to no avail. The diagnostic didn't recognize either device. As the directions advised, I closed itunes, disconnected the devices and stopped and restarted the apple mobile device service, That didn't work either. My wife, who also has Windows 8.1, has the same problem. She installed the new version and it doesn't recognize her devices.
Until now, itunes has been totally reliable. I am convinced the problem is with itunes. Where do I go from here?

I resolved the issue by doing the following:
1. Uninstall iTunes and every Apple application (device support and such).
2. Uninstall bonjour.
3. Reboot.
4. Go to Apple and install iTunes.
It worked. When I opened iTunes (after reinstalling) it recognized all my devices, music and video.

Symptoms
In rare circumstances, an iPhone, iPad, or iPod touch may not be recognized in iTunes on Mac OS X v10.6 Snow Leopard after the Mac is restarted. If you reinstall iTunes, your device may be recognized. However, restarting your Mac may result in the device not being recognized again.
Note: These steps do not apply to OS X Lion or Mountain Lion.
Resolution
Follow the below steps to troubleshoot the issue.
Note: Some of these steps will require that you enter your Mac OS X user password. If you do not know your user's password, follow this article first.
Install all software updates. If you have an update available for an SDK (Software Development Kit), be sure these updates are also installed. Do this by clicking the Apple () menu, choosing Software Update, and following the on-screen instructions. If you need to download iTunes manually, you can download it here.
Disconnect the device and quit iTunes.
In Finder, click the Go menu and then choose Go to Folder. Enter the following location into the text field that appears:
/System/Library/LaunchDaemons
Click Go.
Locate the file "com.apple.usbmuxd.plist~orig" and drag it to the Trash. (Do not move the similarly named "com.apple.usbmuxd.plist" file to the Trash.)
Restart your Mac, open iTunes, and connect your device. If your device shows up in iTunes, restart your Mac one more time and confirm the issue is still resolved.

I upgraded my iTunes to 10.7 on my MacBook Pro - after that iTunes doesn't recognize my iPhone 4S 6.0.1 (10A523) in the iTunes sidebar. Solutions?

I upgraded my iTunes to 10.7 on my MacBook Pro - after that iTunes doesn't recognize my iPhone 4S 6.0.1 (10A523) in the iTunes sidebar. Solutions?
(Both upgrades to the phone and lap-top were done based on Apples suggestion, so I find it strange it doesn't work automatically, which should be a basic reason for choosing Apples costly products!)

Try rebooting your computer.
You might also try downloading and installing iTunes 11 which came out today.

My PC doesn't recognize my iPhone 4s

Hello.
Today I was updating from iOS 6 to iOS 7. Ok, I downloaded the new OS, extracted it and then a backup was made. After the backup, on iTunes, a message appears: Waiting for iPhone.... I waited something about 5 minutes, and when I look to my iPhone, I see this screen:
Then, iTunes showed me an "Unknown Error" and by there, my PC doesn't recognize my iPhone anymore.
And about my iPhone? Well... the above screen is still there.
Someone has any idea to help me?

I 'had' a problem with my computer not recognizing my iphone 4s when I plugged in the USB cord. Tried to find a solution on the internet but no luck as usual. It worked before, but not this time. Tried everything. Finally I tried the original cord that came with the phone. It WORKED! Must have to use an Apple cord with an Apple phone. I was using a generic cord to charge my iphone while on the laptop and it would charge fine. It probably just don't have a wire in it for 'data transfer'.
