iTunes stuck at 'sync' stage after iPhone 12 Pro updated to IOS 7.2

Well done xCowboy. Force quit the process, and the hanging sync finished in about 5 seconds (just music)

I encountered the problem trying to sync from the Music app on my MacBook Pro (M2) (macOS Sonoma 14.2.1) to my iPhone 14 (IOS 17.2.1). Prevailing wisdom seems to point to Force Quitting the MDCrashReportTool process. I was unable to find the process on my Mac UNTIL the Sync attempt was actually running on the machine---then it appeared. Sooo...my steps to sync: 1) Connect iPhone to Mac; 2) Open Finder, and select iPhone; 3) Start SYNC; 4) Open Activity Monitor in the Utilities Folder; 5) Select MDCrashReportTool under the Network Button; 6) Select the "Circle with X" icon at top of Activity Monitor Window; 7) Select Force Quit in PopUp Window; 8) Sync completed in about 3 seconds; 9) Close appropriate windows/apps.

You'll have to go thru this every time you want to sync until Apple fixes the problem.

Thank you for the posting. Stopping MDCrashReportTool, DOES WORK, to at least get by. I am running Sonoma 14.1.2, Music. 1.4.2.83, iPhone 14 Pro 17.2.1. I spent 6+ hours with Apple support, no joy. I submitted error logs and are supposed to get back to me by 1/24/2024. There must be literally millions of users with same problem. Complaints and logged support calls should have reached critical mass for a fix soon. Thanks again for temp fix.

upgrade to 17.3 resolved my sync issue iphone pro 14, Sonoma

Purchased a refurb iPhone 12 from Apple and while setting it up today I also found out that that it wouldn't let backup his phone to my iMac running High Sierra (10.13.6). The new phone is running 17.2.1. When I tried to select the new iPhone in iTunes it said I had to update iTunes to version 12.10.10. What? I can't find a version any higher than 12.8.3 anywhere. Where is this 12.10.10 prompt coming from?

That's an odd glitch message because 12.10 was a windows iTunes. There should be a helper app for iTunes in High Sierra that allows syncing . . . but that OS is over 6 years old at this point so some limited compatibility should be expected.

This has been affecting me too for the last month and it's driving me nuts. I've tried restoring my phone from various backups and nothing makes a difference. Manually "force quitting" the MDCrashReportTool works but is a pretty shoddy workaround. If anyone is aware of a more permanent solution without losing data please let me know (!) wtf Apple!!!

It’s broken again. Useless

Okay, one more time!

For those claiming a "solution", there has been no solution. There exists some "workarounds".

For those claiming it broke in a recent release, they are ignoring the same issue being reported many times in the past 15 years.

For those claiming it "broke again", it can't unless it was first fixed. It hasn't been fixed.

The issue, as I see it, is a software glitch that is raised when the sync process encounters a certain data condition it cannot resolve and fails to properly report to Apple. What is that condition? Only someone with access to the code can say for certain.

When the data sync has nothing to do, it works just fine.

When the data sync processes the data successfully, it works just fine.

When the data sync does not encounter data it cannot process, it works just fine.

When the data sync fails, someone will say, "it broke after a code update".

When the data sync works the next time after a failure, someone will say, "it's fixed". However, if it then fails again they say, "it's broken again".

It's a data driven issue. It's bad software (code) that cannot process some certain out of sync data or if it does process successfully, it fails to report back to Apple.

If anyone can prove otherwise, please share.

-R.

Thanks so much! I was able to find the MDCrashReportTool in Task Manger and that Fixed the whole Sync Problem!

Yeah!

Awesome help tip. I am running an older iMac on macOS 12.7.2 and iPhone 14Pro. Force quit MDcrashreport did the job well. Thanks for the heads up.

There is another thread on music for IOS that discusses this topic. That one has about 50k views, so a lot to people are having these issues.

I have the same problem trying to sync to a Windows PC with iTunes 12.13.0.9. Yesterday I could sync with no issues but today since I updated my iPhone 14 Pro to iOS 17.2 it gets stuck at the 'Preparing to sync' stage.

Hi,

I'm having this same problem. Itunes gets stuck in Sync Mode on Step 2. I'm using Windows 11. I've tried to search online how to use those steps about the Activity Monitor and the MDCrashReportTool. Can you please tell me how to find those in IOS or a way to do it in Window 11?

Thanks for any help you can offer!
