home sharing help
1. can i edit playlists while at work on my mb pro and have them cloud sync back to my imac or no?
If playlists sync via iCloud (I forget if they do), then yes.
2. can i sync my iphone with my mb pro even though the music is not physically there anymore?
Yes: if it's all iTunes music, nothing should change.
3. should I turn on home sharing on the mb pro and if so why?
Depends on if you need to view that stuff from the laptop. Remember it will only be viewable when at home on the same local network.
Right, as long as the account with which you have iTunes Match enabled is logged into iTunes on that computer.
Home Sharing in and of itself is separate.
