I had this problem in the first beta and was hoping that it would be fixed in future betas. Didn't happen. Here's what happens.
1. Attach phone to iMac
2. Open Music
3. Click on iPhone
4. Music opens iPhone (eventually. This is very s-l-o-w)
5. Get a listing of songs on iPhone (this worked sporadically if at all oin first beta)
6. Open Finder
7. Click on iPhone
8. Wait
9. Wait
10. See above.
There is no indication other than the phone showing up in Locations that it's attached. Lots of clicking, lots of fulminating, a dearth of results. Now, this doesn't happen every time. It actually worked right one time after I updated to the latest Beta. Since then, bupkis. No iPhone banner in Finder, no little spinning doo-dah (I think that's the technical term). I actually could perform a sync one time.
Speaking of Sync, just what purpose does the Sync Settings... button perform at the top right of Music? I've clicked it, I've cursored (and cursed) and hit Enter....no purpose, nothing happens, it just sits there smirking and taking up space.
