IPhone with IOS "Trust this computer" keeps popping up

I have upgraded to ios 7 on my iphone, but when I now connect my phone to my car (ipod connectivity) it pops up with the "Trust this computer" box! but disappears quickly and then keeps popping up and disappearing. I don't even have time to click TRUST!!!!
After a couple of tries the car says there was an error and stops trying. What the **** is going on!
If no one knows, maybe you can tell me how to downgrade/restore to ios 7 as without this connectivity I can't listen to my music in the car?

I finally fixed it! Don't know really how but here goes what I did.
You all agreed that before IOS7, by simply plug usb cable between PC and iphone that was it?!
Updated to IOS7, liked it a little, noticed slowness, but was fairly acceptable. My problem started when I was not able to sync my outlook calendar, contacts, etc. to my phone then I freaked out, because kept having this "do you trust this computer again and again when I clicked Trust.... got me crazy.
Someone told me to use iCloud. Did, but I can check my Iphone contacts on a website! not what I was looking for. Then I downloaded ICloud for windows, so I can sync (another procedure) to my outlook. Ran it, restarted, found that my wlan card was disabled, fixed it, restarted (anxious), when back, checked some changes made in outlook, more folders and buttons, but it seemed to work.
I plugged the usb cable and iphone to my pc and Viola! they synchonized!! via usb cable!!
was it the cable? the icloud installation? the rebooting? don't really know, but it works now...
I was this close to return to IOS6 by doing all those creepy steps, but it is ok now...
Please let know if it work for you guys!!
cheers!

"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.

HT5868 "Trust this computer" keeps popping up

The popup "Trust this computer" pops up everytime I connect. Every time, I select "Trust". just like in the instructions here http://support.apple.com/kb/HT5868?viewlocale=en_US&locale=en_US . But it doesn't remember, it keeps popping up
The cable I'm using is an Apple cable, on a iphone 4S and IOS 7.0.2

You must have said "don't trust" once. See: http://support.apple.com/kb/HT5868.
If you go to Preferences in iTunes, Advanced pane, and click Reset Warnings it will prompt you again to permanently trust.

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.

My iPhone 5 got problem when connect with lighting cable, this will keep pop up message "this accessory may not be supported"

My iPhone 5 got problem when connect with lighting cable, this will keep pop up message "this accessory may not be supported", I can't charge or sync at all. I tried plug and unplug many time, still can't detect/charge my iPhone5, but sometime will 'lucky' that can connect to my iTunes and charge battery…
This message will auto pop up also when I don't have plug anything in my iPhone 5, It is very annoying…
The lighting cable is original and now i'm using OS 7.0.4 / iTunes is 11.1.3
What I can do to fix this problem? Thank you.

I would try using another cable you can likely borrow one to test from somebody
if it's the same then likely the connector in your iphone have been damaged

"Trust this computer" keeps flashing!

I have an iPad Air. "Trust this computer" keeps flashing on the iPad when plugging it into my MAC. won't let me select it. All "fixes" I read for for iTunes on a PC. I have not seen any posts for fixing this on an iPad Air to Mac-I iTunes.
My Itunes on the mac is up to date My OS on the Ipad air is up to date.
I want/need to back up the ipad into itunes on the computer but can't get there... I'm fearful of losing everything (mostly pictures) on the iPad.
Help is appreciated.

I would download a fresh copy of iTunes from www.apple.com and install it over the copy that's on the Mac...that's how you fix itunes on the Mac...if you do that and it still does it it could be something going on with the iPad itself....I would first try a different cable...if that doesn't work I would try making a iCloud backup...I would then advised doing a restore...I wouldn't do a restore unless I made an iCloud backup because the restore will wipe the device to try and fix it

Ios 7 - iphone won't trust this computer?

i know people have successfully gotten this to work but for some reason my iphone just keeps repeating over and over and over again the "Trust this computer?" dialog and won't pair the device. i'm trying to do this with ifuse.

I actually managed to mount my iPhone5s runnin iOS 7.0.5. But my older iPhone5 running iOS 7.0.4 wont mount no matter what I do.
I used the iFuse to mount iPhone5s. It took couple of tries.

Iphone repeatedly asks "trust this computer?" when connected to pc

Whenever I connect my iPhone 5 to my work PC in order to charge it, it repeatedly asks the question "Trust this computer?" to the point of extreme annoyance. I always hit "trust", and it just keeps on asking. Is there any way I can make this go away?
Thanks.

It appears that my problem was my lightning to usb cable. Using a different cable on my work PC, I'm not seeing this problem.

Trust this computer on Ubuntu

Everytime i plug my iphone into my pc, it brings up the Trust this Computer screen on the iphone.
i click trust, and it keeps popping up every 3 seconds.
How do i disable this?
I have a Iphone 4 8gb
IOS version 7.1 (11D169)
Running a HP g50 laptop
2GB memory
Intel Pentium Dual core [email protected] x2
Mobile Intel GM45 Express Chipset X86/MMX/SSE2

I think the computer has to be running iTunes... which can only run on a Mac or a PC.
I hope I solved your problem.

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 - 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.
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 iPad, iPhone, 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 have not 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.
Regards,
Sterling

HT5868 why does my iphone KEEP asking if I trust this computer? I thought it was a onetime thing per computer?

Why does my iPhone KEEP asking if I trust this computer? I thought it was a onetime thing per computer? I plug my iPhone 4s into the computer and every time I tell it to trust this computer, but a hour later if I plug in again, I have to say trust again... bug? Setting issue? Help?

http://helpios7.com/trust-this-computer-pop-up-fix/
This helped me. Fix #1 is something Apple doesn't ever suggest to you.
My specific problem was somehow my Apple Mobile Device USB Driver got turned off and moved and maybe even uninstalled, but after hours of struggling, this site helped tremendously.
Furthermore, I could connect my iPhone to my computer but not into iTunes. It would only let me go to access pictures on my iPhone and that's all.
Best of luck to anyone trying to figure out their problem.

Create your own user account on your computer, open iTunes, log into your iTunes account on the iTunes Store then sync your iPhone.
