IOS – iTunes sync error -50

data synchronizationerroriositunesmacos

I recently tried to sync my iOS device, but I got a message similar to this one:

unknown error -50 itunes

I tried googling around, and people generally recommended to disable syncing photos to fix this, but in my case syncing photos was already off.

Any ideas on how to fix this?

I just fixed this by deleting a large video from my iPhone.

Even though I still had about 3 GB left, it seems that iTunes wants there to remain some free space on the iPhone before syncing.

Once I had about 4 GB left, it started syncing again normally.

I hope this helps someone, and for god's sake Apple you could've included a less cryptic error message for such a simple issue.
