Q: Trust this Computer?

This didn't work for me.  As soon as I disabled the device (iPhone) it would no longer charge (which is why I plug into my work computer).  I'm still having the issue every time I plug into any computer.

If you go up a few posts you can try out my solution. Seems to be working for most. I had the same exact problem as you until I did some tinkering. It's step by step instructions that are easy to follow. Keep in mind though, I was running the latest version of iTunes and OS for my iphone 5s. Hope you get it figured out. ~ JT

Perfect!

I have been trying to solve this problem for weeks.

Thank you.

Thank you!   This fixed the repeated TRUST issue as well as my ipad and iphone failed to synch in itunes.  They would be recognized for a brief second, and then would disappear.  I even reinstalled itunes and it did not fix. 

However, going into device manager and repointing at the directory you said fixed everything. 

Huge!   Thanks! 

Thanks bro! This solution really helped me out!

Someone should let the forum moderator know their are solutions- maybe they could post it up in the first page so people don't have to flip through the forum for days. For convenience sake. ~JT

Same problem.  Everytime i have to update software on the IPAD something goes wrong.  This is why I am selling this rubbish and buying a Samsung

This solution also worked for me and my iPod Touch, which would no longer get past the "Trust / Don't Trust" prompt after updating to the newest version of ITunes and iOS 7. Thank you!

Read 10 pages of community chatter - tried everything I could.  Looks like many PC users have a fix for this problem but I haven't seen anything specific for the Mac.

Last night,  I installed the latest upgrade 7.1 my iPhone 5.  When I connect to my main laptop (Mac Book Pro, Intel Core 2 Duo processor and running on OSX 10.9.2), I'm asked if I want "Trust This Computer?".  I select TRUST, wait about 30 seconds and it asks again.  I'm stuck in a loop.

I'm using the offical iPhone cable, rebooted my phone and my laptop, reset my iPhone settings, reinstalled iTunes on the laptop, have plenty of space on my computer & iPhone and still no success.

To make matters more frustrating ....as a test, I pulled out my second laptop (another Mac Book Pro), which I travel with, and it trusted that device so I guess the issue is a laptop issue.

@Patukka

Having the same problem. All of the forums results and online posts have been related to Window's issues, Ubuntu and other non-mac specific issues.

I updated to 7.1 and now everytime I connect to my mac (with an approved 32pin cable plus apple lightning connection) I get the message and get stuck in the same cycle.

(And **** *** Apple, considering I've practically been a showroom for your company for the past 30 years, I should be able to use whatever charging cables I want to use!)

Hope we can see a 7.1.1 that addresses this?

Sadly people are still taking the wrong view of this. Most replies here are how to fix Windows, or Ubuntu or whatever. My issue was with my rental car.. duhh.. pretty frickin hard to upgrade itunes or the OS there... the OBVIOUS (to anyone with any logical sense) is that this is a bug in IOS7...

my iPhone 4s is about on its last legs and ios7 seems to get dumber with each update. this will certainly be my last apple phone.

Sadly I agree

If it where posible to roll back software id in on iOS6 in a flash.

Ram down what you will apple. I wont ever be a customer again.

I’m pretty sure everyone updated they’re phone to 7.1 and they’re iTunes to 11.1.5… and probably plugged their device in the USB port. Then hit “trust this computer”. And STILL couldn’t find it. OR, even uninstalled iTunes a zillion times and then tried a new cord.. I was just playing around with my computer and found the solution for Windows 8 users. And possibly Windows 7 users. For Mac users: try something similar..

1. Plug your device in and do the usual “Trust This Computer” ******** on your device..
2. Hit START on your computer..
3. Type in PC SETTINGS..
4. Click PC AND DEVICES..
5. Click DEVICES..
6. Under OTHER DEVICES, click “Apple IPhone/IPad/IPod”..
7. Click REMOVE DEVICE..
8. Take the USB out.. Then plug it back in..
9. WALLAH..

jordaxius solutions seems to have worked for me after trying everything else.   At least so far it is working

I can't believe that I'm saying this but Windows users seem to have a solution, meanwhile I'm still seeking a solution for Mac users.  I've come across a "solution" to delete the locked files in /var/db/lockdown folder, which apparently has worked for some users who posted on another thread but unfortunately, that solution did not work for me in that the files in that folder did not unlock so I could not determine if deleting those files would allow me to connect my iphone to my Mac.

If you're not sure what you're doing using the command terminal, you may just want to call an Apple rep!

1) open terminal on your Mac

2) cut and past this command in quotes exactly as it is "sudo chflags -R nouchg /var/db/lockdown"

3) enter your password to verfiy (there is a warning message).  Note that you won't see any letters appear when you enter your password.  Just hit enter once you've typed it.

3) now go back and follow the directions on the lockdown page:

4) once the plist files are in the trash restart your computer and try connecting your phone.
