"Trust this computer" no longer displays

So I have made a mistake. I had bought a mba and I needed to charge my iphone 4s. I hadn't transfered all of my data from my old mbp so when I plugged it in, not thinking it through, I hit "don't trust" on my iphone. Now that all of my things have been transfered, I plugged my iphone into the computer and didn't recieve the message. I didn't think much about it, I just simply ticked the box for sync wirelessly. I unhooked the iphone and it doesn't stay paired up. To sync my iphoen, I have to plug it into the computer otherwise the computer cannot find the iphone wirelessly.
What I've done:
"Reset the settings" on the phone
"Reset network settings" on the phone
Restarted computer/iphone
Hooked up my ipad to see if the issue continues onto the ipad, but it works wirelessly and flawlessly
Made sure mba is updated
Continously re-plugged in iphone in case the message pulled back up
Tried closing out of AppleMobileDeviceHelper in Activity Monitor
Figuring it was an iphone problem, opened old mbp and the device pulled up without being plugged in
The computer cannot find the phone with bluetooth, even plugged in
Manual sync does not work unless you connect the phone
The message doesn't pop up with anything I have done and it is driving me CRAZY. I love the wireless feature because I can be anywhere and sync my phone.
Please tell me how to FIX this problem!

This couldn't be further from the truth. I am still asked this occassionally when connecting both my iPhone and iPad to my computer - and each time I've been asked this, I have selected "Trust."
In addition, see the thousands (literally) of threads of others who are experiencing the same issue. For example, a Google search of Apple discussions on the topic gives back 11,600 results:

The iTunes on my desktop is no longer recognizing any of my devices (iPads, iPods, or iPhones). I am unable to sync. And when I connect a device I am asked on the device if I "Trust this Computer". When I hit "Trust" nothing happens. Help?

My iphone 4 will not open in itunes windows. when i try to connect my phone displays a message asking if i trust this computer.

my iphone will noy open in windows. when itry to connect my phone displays the message. Trust this computer? your settings and data will be accessible from this computer when connected.

Well, you downloaded a bootleg copy of iOS 7 beta and have installed it on your phone without being a developer. It has bricked your phone and you cannot get help here because doing what you did has voided your warranty. Have a nice day.

4s Disconnects after "Do you trust this computer" prompt

Recently, I believe after the most recent iTunes update, my iPhone 4s will no longer sync up with my computer. Each time I plug the phone in it gives me the "do you trust this computer" prompt. When I tap yes, it disconnects the phone from the computer. At no point does iTunes see the phone, and I have been unable to put any music/podcasts on it. I have tried to use different usb ports, different cables, and repairing the Apple Mobile Device Software. Are there anymore suggestions my friends.
The computer I'm using is running windows 8. Let me know if there are any more details needed.
Thank you for your time.

Hey there maiddib87,
It sounds like your phone is not staying connected after you tap to Trust the Computer so you cannot use it with your computer. I would use the troubleshooting in the following article to help resolve the issue:
iTunes: Resolve USB-related alerts
http://support.apple.com/kb/TS5254?viewlocale=en_US
See if the cable connection at the device or computer has come loose or unplugged.
Unplug the cable you're using to connect your iOS device from the USB port on your computer, and then reconnect it. Then unplug it from your iOS device, and reconnect it.
Remove any third-party battery packs or cases from the device and ensure that the USB cable is connected directly to the port on the device.
If your Lightning or 30-pin cable is connected to a keyboard, display or USB hub, try plugging it directly into a USB port on the computer instead.
Close any virtualization apps (such as Parallels or VMWare).
These apps may interfere with your computer's ability to communicate over USB if they aren't properly configured, or up to date. If this resolves the issue, contact the developer of the app to see if an update is available.
Restart your computer.
Restart your iPhone, iPad, or iPod touch.
If you're using an accessory or third-party cable to connect your device, try using an Apple cable with the device instead.
Update to the latest version of iTunes if you haven't already.
Disconnect other USB devices from your computer, except for your keyboard and mouse. Then, reconnect your iOS device. If the issue is resolved, reconnect the other USB devices one at a time. Make sure your iOS device is still recognized by the computer after adding back each device.
If one of these steps resolves the issue, but it comes back later, make sure you haven't changed how the device is connected. For example, check to see if you plugged the device into a specific accessory, or used a specific cable that reintroduced the issue.
Thank you for using Apple Support Communities.
All the best,

My ipad asks me repeatedly if I want to "trust this computer" whenever I plug it in to my desktop PC and I can't get it to just connect and be able to sync or access files.

Whenever I plug my iPad into my desktop PC (windows 8.1), the "trust this computer?" popup keeps displaying on my iPad. I tap it but it just beeps and a few moments later it shows up again. Meanwhile, itunes keeps giving me error messages and giving me the message "Do you want to allow this computer to access information on this ipad?" I click continue but the ipad keeps giving me the trust this computer message every 3 seconds. I've never been able to sync this ipad with my computer yet because of this problem. Any suggestions?

I finally was able to solve my problem. I'm not sure why it happened but after updating my iPad to the most recent iOS, it works just fine. I had iOS 8 before, but it was the first release, not the update. I have the latest iTunes on my computer so maybe they weren't compatible. Anyway, if anyone else is having this problem, make sure everything is up to date.

"Trust this computer" message in iPhone 5 each time it's plugged, not recognized by iTunes

iPhone 5 using iOS7 is not recognized by iTunes. It keeps popping up "Trust this computer" message each time I plug it in to my laptop (Windows 8). It shows in my devices in my computer. Both my iPad with Retina display and iPod touch 5th generation are recognized. I have followed instructions for this issue but not working, help!

I just wasted 2 hours of my life with this. Finally figured it out.
If the above suggestion doesn't work (it did not work for me as the above poster completely failed to identify where to find this "MPT" and it was not listed in my device manager anywhere) .....
1) Go to control panel > type Device Manager into your search box there
2) Go down to "Portable Devices" (the Apple help documents are a total fail on this one too as they say to look in "Cameras" after taking a "Screen shot" with the iPhone. Did not work.)
3) Inside Portable Devices you should see "Apple iPhone". If you don't, expand every one of the Device Manager things until you find Apple iPhone listed. Then ...
Then from the Apple support page:
For Windows Vista, Windows 7, or Windows 8
Right-click the Apple iPhone, Apple iPad, or Apple iPod entry in Device Manager and choose Update Driver from the shortcut menu.
Click "Browse my computer for driver software."
Click "Let me pick from a list of device drivers on my computer."
Click the Have Disk button. (If the Have Disk option is not present, choose a device category such as Mobile Phone or Storage Device if listed, and click next. The Have Disk button should then appear.)
In the "Install from Disk" dialog, click the Browse button.
Use this window to navigate to the following folder:
C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers.
Double-click the "usbaapl" file. (This file will be called "usbaapl64" if you have a 64-bit version of Windows. If you don't see "usbaapl64" here, or if there is no Drivers folder, look in C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers. instead).
Click OK in the "Install from Disk" dialog.
Click Next and finish the driver-installation steps. Open iTunes to verify that the device is recognized properly.
Once I browsed to that exact file and installed it, it worked. iTunes popped up and loaded the phone.
Hope this helps someone. There's *no reason* this should be happening. This is a brand new iPhone 5s for me on Windows 8. The Apple help files need to be corrected.

"Trust This Computer" Keeps Popping Up Every Time iPhone Is Connected to MBP

Hi,
I found this question of the forum in relation to Windows computer, but not in relation to a Mac (especially, I did not find a solution).
The issue: every time I connect my iPhone (6 Plus, current iOS 8.2.) to my MBP (Mid-2012 13'', current Mac OS X 10.10.2) I am getting the "Trust This Computer" message, despite that I have trusted the computer (like twice daily, about 500 times) already. According to 'Trust This Computer' alert on iPhone, iPad, or iPod touch - Apple Support the iPhone should only ask me once per computer.
What I have done so far:
- updated iPhone from iOS 7 to iOS 8 (and within 7 and 8)
- updated Mac OS X from Mavericks to Yosemite (and within 7 and 8).
- replaced the cable twice (both Apple, from Apple Store, Australia)
- reinstalled Yosemite (for other reasons)
- repaired file permissions on Yosemite (got this from this forum)
- tried different USB ports
Nada, still asking me. In addition to the annoyance, it is the also apparently not syncing with iTunes.
Do I have options left to make the issue go away?
Thank you for your help!

This just started happening to me after I updated to 8.3.
I haven't had this problem for a very long time. Now, every time I plug into my Mac, 10.10.3, I get this message. I tap on 'trust' each time but it doesn't seem to make a difference.

Trust this Computer - iPad/iMac Message Keeps Popping Up - HELP???

I see plenty of reported issueson this subject, but none that fix my problem.
iMac has latest OSX and iTunes versions, iPad is updated to iOS 7.1. I even tried reinsatalling OSX (thought I'd got away from reinstalls when I dropped Windows!!!).
But I still get bing, bing, bing, bing, bing ... and the "Trust this Computer" pop-up every second until I unplug the (original Apple) USB cord
Any suggestions how to get around this annoying problem - which may have started after iOS 7.1 upgrade.
Thanks!

Hello there TedJ,
It sounds like your phone keeps connecting and disconnecting over and over until you unplug your iPhone from the computer. I recommend the troubleshooting in the following article named:
iOS: Troubleshooting USB-related alerts when syncing
http://support.apple.com/kb/TS5254?viewlocale=en_US
Try the following steps to check the connection between your device or computer. You might need to do only one of these steps to resolve the issue, so test your connection after each step.
See if the cable connection at the device or computer has come loose or unplugged.
Unplug the cable you're using to connect your iOS device from the USB port on your computer, and then reconnect it. Then unplug it from your iOS device, and reconnect it.
Remove any third-party battery packs or cases from the device and ensure that the USB cable is connected directly to the port on the device.

"Trust This Computer" comes up every time

The "Turst This Computer" warning comes up every single time i plug the phone into my computer. Fine once, but is it supposed to come up every time. Each time, i hit "trust" and the message goes away. But if I unplug it, and plug it right back in, same message comes up. I looked in iTunes and on the phone and couldn't find anything that would tell it to remember that yes, I trust this computer.
iPhone 5, ios 7, Lightening cable purchased from Apple store, Dell Computer running Windows 7, with update iTunes 11.

When you plug in to a windows computer, the "trust this computer" message shows up on the PC, and needs to be clicked. I realize that your car isn't a computer, but is there a display that could be prompting you? If not, there may be a new issue as the device is asking for trust verification with no method of acknowledgement. You may want to call AppleCare at 800-694-7466, and report the issue there. They may know of a workaround, or get a workaround started.

HT5868 My iphone 5 with ios 7 stopped promting me to "trust this computer" and wont charge from USB ports now

My iphone 5 with ios 7 stopped promting me to "trust this computer" 1 day ago after doing it everytime i plugged it in to a USB port on my work laptop. It will now no longer charge from any of the USB ports. The USB ports work fine on the laptop for other devices and my phone will prompt me and charge at any other computer in my office. I possibly hit do not trust by accident which may have caused this. I reset all settings on the phone and rebooted my laptop and none of this fixed the issue. Phone syncs and charges fine at home and there were no issues with my work laptop up until 2 days ago with prompts or charging. Any ideas??

Hi,
I'm new on this forum and with my iphone 5c.
'Till some days ago I had a Windows Vista pc and when I connected the iphone, it was recognized.
Yesterday I decided to change my SO in Linux Ubuntu 13.04 but now my iphone isn't recognized and I'm not able to use it.
This message appears on my iphone
"Trust This Computer? Your settings and data will be accessible from this computer when connected via USB or Wi-Fi. [Trust] [Don't Trust]"
I clicked Trust but the iphone buzzes twice, then repeats the prompt. This will repeat endlessly.
I read a lot about the bug, but is there any solutions waiting for the resolution of bug?
I can't use my iphone!!!!

Trust this computer keeps popping up every time I try to sync

I have a iPhone 6 iOS 8.3, Macbook Pro and iTunes 12.1.2.27 and am having an issue with sync.
In iTunes I can see my iPhone, but every time I try to sync a popup saying - Sync failed due to this computer is no longer approved for purchased apps on this iPhone?
I then approve the computer and it states that I now have 3 out of 5 approved computers. I then try to sync again but then the popup comes again?!?!
Am I missing something or is this a bug?
Any help is appreciated and thanks in advance :-)

Hi, jmansa.
Thank you for visiting Apple Support Communities.
I understand that you are consistently receiving a prompt regarding 'Trust this computer' and an authorization alert. Here are a couple troubleshooting steps that I would start with. If the issue persists, please let me know.
