I am in the middle of doing an Erase and Install of Tiger on my PowerBook. It's formatting as I type.

However, I forgot to deauthorise my iTMS account on the machine. I have already notched up 5 registered machines.

My first question is, when I get iTunes up and running again, will I be able to still play iTMS purchased music on it, from my other machine? Considering I'm already up to five registered computers. What information is taken from the computers? OS version, serial number?

If I can't, how can I manually deauthorise it?
 
I've run into the same problem, forgetting to deauthorise before formatting. I haven't had any trouble though, it still only counts as one computer and is probably looking at the serial number.

Interestingly, this seems to contradict some information in the other thread :confused:
 
Yeah, it just uses the computer ID so it doesn't matter if you wipe your hard drive clean, it still registers as one computer.
 
You have to change the configuration (different HD or adding (or removing) RAM, etc) before it will count as a new registration. A new install an unchanged system should only count as one. :)
 
Actually...

It registers the logic board. Until/if that needs to be replaced, you're fine.

More than the logic board:
Make sure you deauthorize your computer before you upgrade your RAM, hard disk or other system components. If you do not deauthorize your computer before you upgrade these components, one computer may use multiple authorizations.
from here... ;)
