iMac does not recognize 5th gen Touch

Re: iMac does not recognize 5th gen Touch

in response to jumperpainter

What do you mean by :iTunes recognizes the Touch, but does not Sync with it."?

What exactly happens when you try to sync?

Does iTunes see the iPod?

iTunes sees the ”3 Devices”,

Nano, Touch and iPad

on the iMac, Finder sees only the Nano

Was the iPod previous synced to another iTunes library/computer?

No

Have you successfully synced from this iTunes library/computer before?

Yes, when the Touch was initially bought.

If so have you done anything like update iTunes on the computer since it last successfully synced?

Yes

Do the songs play in iTunes?

Yes

Does any media now sync to the iPod?

No
iTunes (12.0.1.26), Under Music or Playlists, NO “little checkbox” appears for any tracks, for any album; reference:

“Unchecking Songs

Next to each song in iTunes is a little checkbox. By default, all songs are checked and thus will be synced to your device. To choose what songs will be synced, you'll need to uncheck them. Go through your music library and uncheck each song you don't want to have synced to your iPhone or iPod.”

Do you have the right boxes checked to sync?

iTunes: Syncing media content to iOS devices and iPod

Try syncing using the manual method

Synching shows that it processes thru 4 steps, but looking at the Touch, nothing is added to it from the My Music, Recently Added, library with its newly added albums and playlists.

Managing content manually on iPhone, iPad, and iPod

Tried it, but NO changes when process is run.

Correction: in iTunes, under Songs, all newly added songs show as Checked, but nothing new is synched to the Touch.

I backed up to iCloud, resynched and the newly added albums were then available on the Touch.

Moral:

the old reliable "everything works across all Mac's" is now separated by the two OS's.

Thanks for your enlightenment.
