The iPhone cannot be synced unknown error occurred -50
Your ever seen this error “the iphone cannot be synced unknown error occurred -50″ on your iPhone?
Maybe by now you’ve fixed, but if you’re googling for the answer, the problem is you’ve synced your iPhoto using one particular library, but then changed libraries the last time you used iPhoto. Hence the sync is getting upset because it looks at the default library and that is always the last library you used.
The solution is to go into open the correct library in iPhoto and then go restart iTunes. You will have to setup your iPhoto sync again though if you were syncing only some albums.
In the future, always make sure when you’ve used a secondary iPhoto library, you re-open the one your syncing to your iPhone before you next do a sync.
And yes, it annoys me too that Apple doesn’t let you choose which library to sync.
