Hi All I have major problems with iTunes since my update to yosemite !! The songs on my mac itunes are no longer synced with my iphone. Not even 10% of the songs I had on my iphone itunes are there anymore, even though the same boxes are ticked. One album that contains 98 songs on the mac has 6 songs on the same album on the phone. Songs that i import to itune (dropped from other folder) are grouped in a album. If I than add some artist or title to a group they are added as additional album. I'm scared to sync now as i fear even more music is lost. Why does Apple change things that work fine, and doesn't add additional features for those who want them instead?? Please this whole update is a mess on my machine!
