New computer, will iPod work?

You will have to reformat it for mac OS X if you would like to be able to install software updates, if not then it will work 99.98%

 

Only if you purchased music/movies from iTunes. If I'm not mistaken, iTunes lets you authorize up to 5 computers. It's up to you.

 

Please, DON'T forget to deauthorize your PC before you get rid of/reformat it. I've made the mistake of not deauthorizing a few times. There were a few times where I forgot to deauthorize before reformatting it, and the time I forgot to deauthorize before reformatting it for the last time and giving it to my cousin. I fixed it with "Deauthorize all" last year, but you can only do that once a year.

 

Good point. I forgot to mention that. Anyways, good luck with your iMac!

 

I've seen people mention the Deauthorzie All only working once a year, but I am SURE I've done it more frequently than that... is this a relatively new rule?

 

I think it's just up to Apple, kind of like them letting you re-download music that you lose and don't back up, even though the official policy is different.

 

I'm pretty sure I didn't even need to call Apple. I just clicked on the Deauthorize All machines option in iTunes and it did it. Maybe I'm crazy though!
