iTunes could not backup iPod Touch (after system update 21/10/2015)

My iPod Touch (iPod1,1) usually sync and backup fine.

After today OS X El Capitain System Update (21/10/2015) it will not sync or backup.

All steps here will not work:

Tried to restore to factory default twice, and even rename the iPod factory name just in case

Remove in iTunes and in folder the backup folders.

Still not working.

Thoughts?

After contacting Apple Care, the answer is that iTunes 12 does not support 1st gen iPod Touch.

I can sync, but always get this message and iTunes freezes often while doing this.

But when I eventually resync, I can sync content even if not supported.
