syncing iPhone (ios14) with High Sierra using itunes

I received message to update my iPhone Xs to IOS14.0. I connected to iTunes on iMac with High Sierra to do make a backup to the computer first while doing the download only. After download was completed, I selected update but nothing happened. I disconnected and reconnected, saw the update button, but nothing happened when clicked. I disconnected and decided to do the update and install from the iPhone directly. Upon completion, I reconnected to iTunes, heard the usually beep, but NEVER saw the iPhone icon in the left corner. So now there is not way to do any backup or update to computer nor can I get to the recent backup on computer to restore (I can use yesterdays backup to iCloud on phone if needed, but not as ideal as more recent computer backup). I have restarted iMac and restarted iPhone but nothing. Of course this computer version will not use the Finder for syncing so what to do now before restoring from iCloud phone backup as last resort.?

For iOS 12 or later you need iTunes 12.8.0.150 or better running on OS X 10.11.4 or better. See How to upgrade to OS X El Capitan - Apple Support if required. iOS 13 & 14 require iTunes 12.8.2.3 or better.


Assuming a suitable version of iTunes is in place then in Finder use the menu item Go > Go to Folder..., copy the following text, paste it into the dialog box and press enter:


/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/Current/Resources


Unlock your device and connect it to USB. Double click on MobileDeviceUpdater in the folder that has opened. It should notify you of a software update. Install it and iTunes should hopefully recognize your device.




I've assumed that if iOS 14 is supposed to be supported by High Sierra then this method which worked for iOS 13 will work for iOS 14 too.

Turingtest2's suggestion just worked for me. Many thanks.


I got a new (2nd hand) iphone 8 today. I connected it to my iMac to transfer the contents of my old iPhone but the i8 and the Mac could not "see" each other.


I called Apple technical support and was incorrectly told that the High Sierra on my Mac was incompatible with the iOS 14 on my i8. I was advised to upgrade to a newer version of the Mac OS (I do not want to do that) or transfer the data via iCloud and WiFi (a very slow process).


I stumbled across this thread. Followed the steps set out by Turingtest and hey presto - it worked perfectly.


Well done and thank you.


Hope Apple technical support read this.

Same problem here, but it's Nov 17 2020! I'm still wondering if there is some sort of Apple bug. My message is the same network issue, can't download the update file for iTunes - but I'm running iTunes 12.8.6.3. I should be good, right? Unless the updater has a problem with something that would seem widespread and quickly fixed. Can anyone help? I've tried all of usual things (restarting, exhausting all options I know to install iTunes update) a number of times, and I can't get around it.

Let me clarify with new info - iTunes will not recognize the iPhone now running 14.2 (updated tonight using iPhone ONLY thru network). But FINDER WILL recognize this 14.2 iPhone and prompt for the update.


There is Software "Security" update 2020-006 10-13-6 perhaps waiting to update iTunes error, although the security update mentions IOS in ways I'm not sure what mean - maybe that these were iOS date releases.


Security Update will not install. Period. It refuses is all circumstances. "Could not connect to the server(-1004)".


I beg for any insight!

Thank you turingtest2 your solution worked for me. I can now sync all my ripped music on iTunes back onto my iphone 12 pro which was lost when i upgraded from iphone X.

I am running macOS high sierra 10.13.6 on a 2010 iMac with iTunes 12.8.2.3

I even downloaded the latest version of iTunes to my pc laptop which did connect to my phone but couldn't bring myself to start ripping again so had one last look for a solution and found your post, worked brilliantly in minutes, thanks again.

Thank you turingtest2! That was a great fix! Could not find a fix. I retired several years ago after supporting Macs for 22 years and frankly I've become lazy with my own gear (waiting for new Macs!) and that was one of the most obscure kind of patches I've run across. Force marched to the future we are!

High Sierra 10.13.6, latest iTunes (v. below is with patch installed)

Some might give up on the long install time but after about 15 min. iTunes 12.8.2.3 patch installed and it now sees iPhone Xr/14.4.2. Brilliant.

Thank you!

Hi,

iPhone Plus, with iOS 14.4.2

Macbook Pro with macOS 10.12.6 Sierra

iTunes 12.8.2.3


After updating the iPhone to iOS 14.4.2, iTunes no longer recognizes the iPhone. I tried updating iTunes to 12.8.3 as suggested, but I get the message "an update is required", which appears to be an OS update instead of an iTunes update, and there's no info as far as what OS version will be installed.

Am I hosed without updating macOS to who knows what?

Thanks to tt2 !

I had an iPhone SE (2016) on iOS 14.5.1 that did not connect to my Mac running (outdated) HS [10.13.6 (17G14042)] and iTunes 12.8.3.1 .

Indeed, I thought I had run this special updater that will be restarted in this way sometimes earlier. Maybe it failed? Not sure.


Anyhow, following the advice now everything seems to be fine, I could make a backup to my Mac.
