iPhone se sync problem

Hello nadeemachmad,

Thanks for the followup. To clarify, if you go to Settings > General > About > Name, on your iPhone SE, what is showing as the name? If it's the same as the iPhone 6s, try changing it and then attempt to sync with your MacBook.

Best wishes.

Hello nadeemachmad,

Thanks for using the Apple Support Communities. We understand that you're having issues with your new iPhone SE and syncing with your Mac. Did you happen to install a backup from your iPhone 6 to your iPhone SE? Just trying to sort out why the Mac would identify it as a different model device. If you go to Settings > General > About > Name, is it named as an iPhone 6s?

You mentioned that the error you receive is related to storage. If you connect to your Mac and follow the direction in article, How to check the storage on your iPhone, iPad, and iPod touch, section: Use Finder or iTunes to check the storage on your iOS device, is the amount of free storage shown a match to what shows on your iPhone?

As for the songs you're unable to sync, are those iTunes purchases, MP3's from elsewhere, or from CD's you've imported to your music library?

Best regards.

Hello nadeemachmad,.

We appreciate you continuing to provide us with updates. Given that the storage amount isn't showing up accurately for what's available, it would be good to contact Apple Support so they can look into this with you. You can reach them at Get Support.

Take care!
