My hard drive died yesterday. I took my iMac into the Apple Store and will be getting a replacement. Here's the thing... My last time machine back-up was in May. I've purchased some music (which now reside on my iPad and Apple TV) and some tv shows (which all reside on my Apple tv) since my last back-up. How do I transfer the data back onto my iMac from my devices? Will it just know when I sync them?
