The iPhone cannot be synced. An unknown error occurrred (-50)

I upgraded my unibody macbook to OSX Lion, iPhoto to '11 from '09 and iTunes to 10.4. Now, my iPhoto library no longer syncs with my iPhone. It gives error "The iPhone cannot be synced. An unknown error occurrred (-50)".
Any ideas why?

Okay, I looked at the MAC log and found that a daemon was busying up iTunes and my system in excess. The cause was RIM software to support my daughters blackberry. Since she now has the software on her laptop, I deleted mine and that fixed that problem.
Researching other entries in the log pertaining to iTunes, I found that esentually iTunes 10.7 is basically broke. With iTunes 11.0 coming very soon, Apple will not want to worry about any bugs with 10.7.
Consequently, we have to just wait and hope that the iTunes version will be better.

Stephen's got you covered.
I've also seen the following reported cause/workaround:
After several Google searches I found the iPad syncing problem to be caused by iPhoto 9.4 not handling the & correctly in names. It's not recognizing them as & which is causing problems with XML. You can manually change them or wait for Apple to issue a fix to iPhoto 9.4. I started to do the manual fix & I just have too many to change.
(Manual renaming isn't going to be an easy/good workaround for a bunch of folks, though.)

I upgraded my iphone 5 to iOS 8 and now i get an itunes error message when I try to sync "this iphone cannot be synced. Unknown error.

I upgraded my iphone 5 to iOS 8 and now i get an itunes error message when I try to sync "this iphone cannot be synced. Unknown error. (-50). my icloud drive was stuck in an upgrade cycle, but i've stopped that and still get the error message.

I restarted itunes and tried again (based on a similar question/solution from 2012).
I don't get the error message anymore, but it's really sort of odd that after step one of sync, it looks as if sync stopped, and then all of a sudden you see step 4 of sync.
Also before the upgrade I had 7+ gigs of space free and after the upgrade I have 10 gigs free. seems like something is amiss, but it's not like I have anyway of determining that.

IPhone cannot be synced - an unknown error occurred (13019)

I have the blues. My iPhone cannot be synced and is rejected in iTunes with the message:
"The iPhone "my iPhone name" cannot be synced. An unknown error occurred (13019)."
Can someone here help me.
TIA,

I have a similar problem. After having a lot of drama with backups freezing and not completing I had to click on the 'x' to procede with any sync's. Now that 3.0.1 came out I decided to update when the popup came up saying would you like to update.
I went ahead, it downloaded the update then it couldn't install it and came up with errors. then my iPhone displayed the USB cable and the iTunes logo on the screen, now it won't do anything and iTunes won't recognise it.
I've tried to reset it, and reset my computer but nothing works. I am not uninstalling iTunes and re-installing it to see if that works. I now have lost everything on my iPhone I presume.
I am furious.

The ipod cannot be synced, an unknown error (13014) ocurred - this is the error message I am getting when I am trying to transfer purchases from iPod. Problem is unless I transfer I am failing to update my IPod touch to iOS 6.0.1

I need to update from 4.3.3 to 6.0.1 so that my apps can take in relevant updates and brun properly. However, update is failing midway on error -5000 and the only way seems to be transferring purchases on ipod to itunes as being suggested by onscreen prompt just when I am undertaking the update. Problem is I can't even do the trabsfer as IPod wouldn't sync properly....error 13014. Has anyone come across this before and resolved it successfully?

"The iPhone cannot be synced. The required disk cannot be found."

I have been having this problems since I got my iphone last year. Early on the phone would sync after 2-3 tries but as of the last 2-3 months I have been only able to sync it 2-3 times even after trying all the solutions presented by the troubleshooting and reading forum posts that seem to have a similar or near similar problem.
The first message I get after having the phone sync is
"The iPhone cannot be synced. The required disk cannot be found."
After itunes attempts to sync again I get a different message that says
"The iPhone cannot be synced. An error occurred while writing to the device."

I had the same problem and fixed it.
"The iPhone cannot be synced. An error occurred while writing to the device."
I think it is caused by downloading too many apps, or large apps, and then when syncing over USB it doesn't recognise the iPhone and you get "The iPhone cannot be synced. An error occurred while writing to the device."
To fix this:
1. Ensure iTunes is closed & iPhone is disconnected but keep USB cable connected to iPhone
2. hold down CTRL + SHIFT on your keyboard
3. connect USB cable to PC and wait. If iTunes doesn't start for a minute then start it (keeping hold of CTRL + SHIFT)
4. if it wont let you start iTunes or all your icons are selected then release CTRL + SHIFT
5. when iTunes starts it may ask you about safe mode or something similar, say yes
6. Your iPhone should list as a device as normal, click sync.
It will then start the sync as normal and you may find it will transfer only one or two apps and you may get the dreaded error message again as I did. However, persist with the above steps and eventually it sync'd all my apps with no error message. Because I have only just done this I haven't downloaded any more apps so it might be a frequent thing but better than the error message.

Error duing iphone sync: The iphone cannot be synced. An unknown error occurred (-50).

I am trying to Sync my 3GS with itunes, and I get the error message: The iphone cannot be synced. An unknown error occurred (-50).
Latest rev of itunes installed.
Any suggestions on a fix?

I'm having the same issue. After updating all iOS devices to iOS 6, then updating all software on my iMac to the latest versions (including iPhoto 9.4), everthing was working as it should. I was able to sync all of my devices (New iPad, iPod Touch, iPhone4) with the iMac early this morning.
Subsequently, I opened iPhoto for the first time since installing 9.4, a window popped up informing me that my photo library had to be converted to work with the iPhoto 9.4. I clicked okay, and let the conversion process run its course.
About ten minutes later, I attempted to once again sync my iPad with the iMac. The sync process would run for a few seconds, then stop with a window popping up saying "The iPad cannot be synced. An unknown error occurred (1140)". I then attempted to sync the iPod and my iPhone, with the same results.
After consulting the discussion forums, it looked like lots of other users are encountering the same problem, and that it was somehow related to the new iPhoto. Someone suggested turning off syncing photos from iPhoto, which I did. With photo syncing turned off, the rest of the sync program now runs without a problem.
I've submitted a bug report to Apple. Hopefully, enough other users have done the same, and Apple will fix whatever it is that's causing the problem.

The iPhone cannot be synced. An unknown error occurred (13213)

I "upgraded" to iTunes 8 and iPhone firmware 2.1 this morning. On the first attempt to sync I get the message "The iPhone cannot be synced. An unknown error occured (13213)" which is not very helpful.
I unplugged the phone from the computer, restarted the phone, closed and restarted iTunes, and the problem still occurs.
How do I fix this?

I had the same error - I was getting it dozens of times after upgrading to iTunes 8.0, installing iPhone 2.1, *+and enabling Genius+*. I have not upgraded QuickTime to 7.5.5 yet.
*Update: it seems Genius is indeed to blame. People posting in this thread http://discussions.apple.com/thread.jspa?threadID=1706466&tstart=60 say turning off Genius resolves the problem for them: "Go to iTunes 8 Menu Bar. Store ->Turn off Genius"*
Specifically it happened on the first sync after I'd turned on Genius, during the part of the sync while songs were being updated on my iPhone. I had about 300 songs to update (because of smart playlist updates) and it seemed to be happening on some but not all of the songs. I clicked OK to the error a dozen or three times, and finally canceled the sync with over 100 songs left to sync.
I followed the process doc007 described: "Close iTunes 8. Plug the phone/touch back in (which should start itunes and turn on the device) I think that was it."
That did not resolve it for me. I still had about 114 music files left to sync, and I was still getting a few more 13213 errors.
I'm going to feel silly if this is completely explained in another thread, but I'm still clicking OK to the errors for another few minutes....Ok, now it has finished, and it says it synced successfully. And...yup, looks like it did sync successfully. Except for all those 13213's.

The iPhone cannot be synced. An unknown error occurred (-39).

Last couple of days--since the new 4.3.5 update, it seems--I have been getting this message each time I try to sync my iPhone:
The iPhone cannot be synced. An unknown error occurred (-39).
Or, sometimes, I get this one:
The iPhone cannot be synced. The required file cannot be found.
It's happening in Step 4 of 4 of the sync, during photo deletion.
Any ideas how to resolve this, please? I've restarted the iPhone and computer, both, numerous times but can't seem to shake this one loose.
Thanks!

Did a little digging online and found a solution:
This error is associated with the iPhoto library.
Navigate to <username>/Pictures/iPhoto Library
Right-click on iPhoto Library and show package contents.
Remove the folder iPod Photo cache (delete it, move it to Trash or whatever - just remove it from the iPhoto Library).
Sync the iPhone. The photos will reverify and it's done. Almost. It will take some time if you have thousands of images...

The iphone cannot be synced. An unknown error occurred (13019)

After reading discussions on this error, I found a fix and had to share.
I have the iPhone 3G (16G). I upgraded iTunes and iPhone 3.0 When I tried to sync, it gave me the error "The iphone cannot be synced. An unknown error occurred 13019"
I unchecked the Music> Sync Music option. It gave me the "Are you sure you do not want to sync music?" I chose the Don't Sync Music button and the sync was successful.
I then checked Music> Sync Music option and was able to successfully load all of my music back... granted, it took time to reload.
I'm no expert, but since it worked for me... I figured it was worth posting.

I have the same iphone and I have not been able to access my music in weeks. I keep getting that error 13019 when I would sync up.
Thank you for taking the time to post this fix! It definitely works. It does take a while after you unsync the music to put it back on but at least I have my music again!!!
