An invalid response was received from the device?

I cannot suggest anything. Unfortunately, you cannot sync a newer iPhone, iPod, or iPad with iOS 10 if you do not have the latest version of iTunes which requires specific computer operating software. You need to make sure that you understand the requirements before updating any device, be it the iPhone, the iPhone iOS, or the computer OS.

Not exactly sure why you picked me out of all the responses here, but that is the best I can tell you, considering I have no idea what your problems are.

The original posting is 3 year's old, Chris, and you have to wade through a lot of posts to come to a solution. What do you suggest to Apple customers with older hardware that does not seem capable of upgrading to newer versions of iTunes?

Either buy a newer machine that meets the minimum requirements for the current version of iTunes, try running Windows 7 or higher in a VM or using BootCamp and use iTunes for Windows, or forgo syncing the device with iTunes.

This is a mess. I upgraded the software to the latest version for my Iphone6 and now it wont sync with my imac. I have always bought all Apple products just so that I would never have this problem and I am increasingly finding it more and more difficult to be an Apple supporter. I have apparently authorized 5 out of the 5 computers I am allowed - don't know what will happen then.

I am going to go back to my old Iphone 5S and hope that still works. Was planning on buying anew Imac but thinking that one of the Samsung products could be a better bet.

As far as the problem with your iMac, you need to find out if it is compatible with the required OS X. If you have been on all Apple products, then you should have been aware of the requirements for using iOS 10, since that was indicated in the release notes.

If you have authorized 5 computers and don't remember them all, you have the option to deauthorize all and then authorize only your current computer. Understand you can only deauthorize all only once a year.

However, if you believe Samsung will meet your needs better than Apple, you are welcome to make those changes, no one here will be affected, nor judge your decisions. You are free to make those on your own.

Thank you to the person(s) who recommended upgrading to iTunes 12.5 for this problem; I got it to work!

I have an iPhone 5 and a 2009+ iMAC originally running OS 10.6-7. Before I started, I was up-to-date with all programs on my phone and computer (thus why I couldn’t not sync my pictures!). I found and downloaded iTunes 12.5, but had to update my OS to make everything communicate optimally. It took time and patience, but I updated to OS 10.10 then decided to go all the way to OS 10.12 (Sierra). In the process, iPhotos updated to syncing condition, and iTunes 12.5 did as well. I can now take photos off my phone, and load saved libraries back on to my phone.

Fortunately, my old Adobe Creative Suite (CS4) also works with all the changes, after I installed a JAVA upgrade.

You got that correct... this iTunes failure issue with the ios 10 with poor notification is a total BS fail! Since Steve Jobs passing Apple is now in corporate care taker mode. SW Quality Control has already quickly slipped to Microsoft & the rest of the SW industry poor lazy incompetent levels...

Well yes I could throw money at the problem (Perhaps Father Christmas will bring me a shiny new Mac). However, the issue is; why should I? Why should I waste a working computer? Why should I have to use a different operating system? Why should I have to spend hours trawling the web for answers? Trying to get my phone to work with my computer is not a diverting past time for me.

You can understand the frustration with Apple that is expressed in some of those comments. All that is required is a more up to date and honest error message.

Why should you? Seriously? Time and technology march ever onward. You don't have to buy a new machine, or use a different operating system if you don't want to. But if that's the choice you make, don't whine about how your brand new tech doesn't work with the stuff you have that's 7 or 8 years old, or even older.

Update your iTunes. But not through iTunes but go to your browser and download the setup program to ensure you have the latest version of iTunes.

Same thing happened to me and I re installed the latest iTunes from the apple site and it fixed the problem

Hang on Tim. No need to be rude. I had a genuine comment to make and, yes, I was serious. I am perfectly well aware of the progress of technology. In my professional career I started working with cassette loaded BBC Bs, I introduced Apple computers into my school, and I continue to work with them every day of my life.

So just to make it clear: firstly, I am not keen to throw anything away that still works, not because I am a Luddite, but because I have serious concerns for the environment in a throw away society, secondly I still think whoever moderates this site could do more to keep the information up to date (see my previous posting) and lastly a more accurate error message would alleviate much of the frustration expressed in many of the above comments.

Apologies, Chris, but your name is at the top of the posting quoting a support document from 2013, which I (& others?) found very misleading.

Then you should understand why it is completely unreasonable to expect brand new state of the art devices to work flawlessly with operating systems that are 3 major versions out of date and hardware that's over twice as old.

Apple doesn't keep the system requirements a secret.

I'm glad you still get good use out of your old equipment. Heck, My 2011 iMac is still going strong. I see no need to replace it until it's no longer capable of running the current version of macOS. It sounds like you've already gone past that point.

Aaaannnddd...... I think that you are missing the point.

I fully buy that I might expect that old software is no longer supported by my newer tech. (I was really ****** that Freehand was no longer supported but hey, you move on.) What we are talking about here is basic functionality. I am simply trying to see the pics on my iphone 6 and put music onto my phone. It worked last week before the latest software update on the phone, now it doesn't.

I don't think that this is asking too much? Or are we going to be such "supporters" of Apple that they can do whatever they want and we customers will just suck it up. Don't think so.

Is it asking too much? Yes, apparently it is. This is a technical support forum.

If you want to whine and bash on Apple about the choices they made, then use the contact us link at the bottom of the page and send them feedback.

These forums are not the place for your complaints. The Apple Support Communities Terms of Use make that clear.

Listen here. My initial question was to ask for help with this issue. So far all the response has been was to buy a new machine. As a tech forum surely someone has a HELPFUL suggestion. But thank you for your kind words. AH
