View Full Version : Don't forget to de-authorize before Leopard install.

Just a reminder to all Leopard installers out there not to forget to de-authorize your iTunes purchased music on your macs before you do a clean install of Leopard. Otherwise you'll loose one of your 5 licences. :)

EDIT: I believe this is only for fresh install, not for upgrade.

Even if you upgrade install?

Nup will be fine if you upgrade

couldnt you just de-authorise all of your computers through itunes, and then re-authorise them as you use them?

I've never de-authorised my Mac before doing a clean install and have not had that problem. It's still the same computer with the same account details.

Yeah, I assumed it used the serial no. or something...

I may be mistaken, but normally you don't have any problems re-authorising an existing machine in iTunes, even if you've otherwise reached your 5 machine limit.

I've re-authorised my MacBook Pro at least 20-30 times over the last 9 months or so because of clean installs or as a result of iTunes crashing and losing the authorisation data. I've never had a problem with the re-authorisation because iTunes recognises that the computer is one of the 5 already authorised machines rather than a totally new machine being authorised.

the id it uses to authorise is not your serial, my machine is dualbooting leopard and tiger and it wants me to auth leopard.

it uses a unique UUID for the machine that changes every time you reinstall - but upgrading doesn't require authorising later on.

Yes but you are limited to doing that once a year. Not a good practice in general, if you can do it by other means.

Don't forget to de-authorise your Adobe software too,
it would be a pain to re-activate your software again if you don't because they are very strict with licensing and activation.
