Q: Updated my iPhone to iOS v9, now can't use it with my iTunes

Same problem here on my Mac Pro.

The news doesn't get any better. Yes iTunes says that version 12,3 requires OS X 10.7.5 or later.  But when you download and try to install it, it says you need 10.8.5 or later.

So Apple hasn't updated their download page yet.

That means I'll have to skip iOS 9 on my iPhone.  I'm not buying a new computer just to have iOS 9 on my iPhone.

I Need the ability to sync my contacts and address book with my Mac when I plug the phone into it.

I Have zero interest in buying a new computer when the only thing mine won't do is sync with iOS 9.

THis is probably the end of the line for me with Apple sadly. 

I've been through a lot of years of these revisions that break compatibility.  I'll probably go Android and Windows next round. All my old PC's are still supported by the latest Windows versions. And here I am unable to update my phone just because Apple artificially disabled newer OS X versions from installing on my Mac.

I wonder if there is anyway to downgrade to iOS 8?

I was having the same problem with my iPhone 5S, but all seems to be solved now. When I originally downloaded iOS9 I did it via iTunes.

I restored my phone to iOS8 http://www.macworld.co.uk/how-to/iosapps/how-downgrade-from-ios-9-to-8-7-reinsta ll-ios-8-3522302/ and downloaded iOS9 via the phone. No problems now connecting to iTunes.

I hadn't updated my iPad 2 yet, after having the problem with the iPhone. So once all was well with the iPhone update, I went ahead and updated the iPad without any problems. There again, downloading the update via the iPad.

Same Problem

There we go! Worked a treat!! Thanks....

Same problem here, running OS X v10.6.8. *Why* couldn't Apple warn us that iOS 9 will break the sync between our devices and our Macs???

I have kept OS X v10.6.8 running because it is 100% stable with my various non-latest graphics apps - if it ain't broke, don't fix it! But now I am downloading OS X v10.10.5 having read all the bad reviews, just knowing that this is going to cause me a load of pain and time wasted.

I have a love-hate relationship with Apple, and right now it's in the 'hate' phase

Similar problem...

On Mountain Lion (10.8.5), and iTunes 11.4. Updated iPhone 6 to 9.0 using over-the-air (OTA) update. All fine, updated to 9.0.1, all fine.

Did the same with my 1st gen iPad mini, 9.0 went fine. 9.0.1 also went fine, but now will not connect to iTunes 11.4. Why does iTunes care about different devices? Is this a bug in iOS 9? In fact, if I were to consider this logically, I'd expect the iPhone 6 to require the newer iTunes as it has newer hardware and capabilities.

I put the iPad into Recovery mode, and Apple has apparently *already* stopped signing iOS 8. So, I'm stuck with a factory-fresh, un-restorable iPad. If Apple's only answer is to upgrade to the worst piece of software they've EVER made, I'll politely (maybe not so politely) decline.

Except the fix requires connecting the iPhone to iTunes. ??? I have to connect to iTunes so I can downgrade my iOS so I can connect to iTunes. Am I being punked???

My bad. http://www.idownloadblog.com/2015/06/10/downgrade-ios-9-beta-ios-8-3/ Putting it in this mysterious DFU mode lets it connect to the older iTunes.

I had trouble getting iTunes to recognize the 8.4 ipsw, but this cleared that up. http://osxdaily.com/2010/11/23/how-to-use-ipsw-files/

Hold OPTION when you click Restore.

You probably meant 8.4.1, as Apple stopped signing 8.4 on the 23rd. Luckily, this worked for me, as well. Downgrade in Recovery Mode to 8.4.1 (see difference between DFU and Recovery Mode: http://forums.macrumors.com/threads/dfu-mode-vs-recovery-mode.1864320/), restore from—I'm ashamed to admit—an old backup, upgrade directly to 9.0.1. In my case, I updated 1st from the iPhone directly (OTA update). The 2nd time, I waited for the long download via iTunes and it worked. There doesn't seem to be a consistency here, except, possibly, it's happening to people who updated to 9.0, then to 9.0.1.

I pride myself on doing things the "right way," as Apple describes, and keeping my gear in prime condition, but I've had many problems lately. I've begun to think it was just me, but now I'm starting to recognize that it's simply shoddy testing, and constant racing to update to yet-another-broken-software-upgrade.

The old days of "It just works" are gone.
