How do I sync just one CD from my MacBook Pro to an iPhone?

Hey englishann,

Thanks for using the Apple Support Communities. I understand that you wish to sync one CD to your iPhone. To do so, you can configure your Music sync settings for selected playlists, artists, albums or genres:

Sync your iPhone, iPad, and iPod with iTunes using USB - Apple Support

[…]

5. You can turn on syncing for Music, Movies, TV Shows, Podcasts, Books, Audiobooks, Tones, Photos, and Info. To turn on syncing, click the content type from the list under settings, then click the box next to Sync [content type]. If there's a check in the box already, syncing is turned on for that tab. To turn off syncing, uncheck the box.

Thanks,

Matt M.
