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

The issue that Apple needs to address is that this doesn't solve the backup issue :/ But it looks like this thread is getting a lot of views and comments so hopefully the problem will be fixed soon.

Yeah- there's something to this point. Very limited incentive to bother fixing an issue that doesn't go to functionality they want to promote.

I have an m1 Mac that wont compete the sync with my 13 pro iPhone. I tried Force Quit "MDCrashReportTool" but that only ended the sync. & the issue still continued, I also tried fully ejecting and clearing trusted computers, & replugging in my iPhone to agree trust computer again. but the sync still wont complete.

there might also be a problem with the "me too" button on this community for some users; for example when i click it, it just spins and spins (may have been to do with lockdown mode)

commenting to increase visibility for this issue, which i also see on iphone 15 pro 17.2 and sonoma 14.2

I unpaired my watch from the phone, and it allowed sync to finish without having to force quit the MDCrashReportTool. Paired the watch again, using an old backup, Sync stopped working again. Unpaired and then re-paired as a 'new watch' and then uninstalled all of the 'non apple' watch apps from it (using the watch app on my iphone), and sync works. So that seems to indicate that it's one or more of the watch apps that I've been using, some of which may be older. So, now just need to determine which of those is the offending watch app. Wish that Apple would give some error feedback on issues like this, during sync or watch setup. Using IOS 17.2.1, Mac OS sonoma 14.2.1, Watch OS 10.2, for what it's worth...

I spoke to Apple Support three times regarding this issue. There appears to be no solution other than deleting the crash report. It doesn’t appear that anybody at Apple is working on a fix either. I write that as this issue appears to have been around for years. This said I have only had since updating to OS 14 and 17 on my Mac and iPhone respectively.

Heres my beef with the situation. I’ve been using iTunes since before the iPhone came out. My music collection is extensive I have spent thousands in the iTunes Store. And hours importing my old CDs and vinyl to iTunes.

To now be unable to flawlessly sync my music from my Mac to my iPhone is bonkers. It’s a core feature. I’m not technical and don’t want to be going into a back end process to delete a task that is trying to report the fact the software is not working to the people that made it. (And the devices it’s running on).

I don’t want to spend anymore time on chat with customer support. For the record both the reps I spoke to and the supervisor who called me back were extremely polite and helpful.

I do want somebody at Apple to confirm the issue is being addressed and the timeline of the release that will fix it.

Thanks.

Another possible work-around. Has anyone tried turning off their watch before syncing? I've kept my watch off while syncing for the past two days, and it's gone through without me having to force quit MDCrash. Tomorrow, I plan on turning off WiFi / Cellular / Bluetooth on my phone to see if that is another workaround. Maybe the problem only occurs if the phone and watch are in communication with one another?

I posted this yesterday, but it looks like I did something wrong. Apologies if this is a double post.

I have reached out to AppleSupport about this. I didn't get connected to an engineer, but the person I spoke to said that yes, Apple is aware of this issue.

Hopefully, they address this soon. I use music daily.

Yes, Apple Support should know about the issue since it has been around for approximately 15 years. Sadly, I do not think we'll see an update forthcoming.

For a summary of the issue (shameless plug to follow), I've compiled info from multiple message threads into a single post: Summary of Issues: MDCrashReportTool, Backup, Sync, Preparing to Sync

Information like what does the "Mobile Device Crash Report Tool" do?

Maybe "Extracts log reports from the device and submits them to Apple (if selected)"?

I think you need the luck more than I do.

Hope you get it.

erksworld, thanks for your response and for sharing.

IMHO, getting information from Microsoft about an Apple process is not my idea of viewing the code to see what it does. While the info may be accurate, it is still too high level for what the process actually does.

Thanks for the good luck wishes. Whatever good comes our way will hopefully benefit us all.

I was really hoping it would. I got all excited when I saw the available update, but nope.

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

This worked for me but it appears it will be a continue problem until a REAL fix is made to the software. Thanks for your help!

I am running IOS 17.2.1 and MAC OS Ventura 13.5.2

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

Thanks for this. Looks like the 17.3 upgrade fixed the bug (!)

The bug is still there if you try two synchs in a row!
