Prepare MacBook for sale when OS X Lion reinstall requires Apple ID I'm going to sell my Macbook Pro.

When I reinstall OS X Lion, I have to enter my own Apple ID. Another Apple ID won't work, I get message "This item is temporarily unavailable".

How can I deassociate my Apple ID with this computer so that the next owner will be able to reinstall the OS with their own apple ID?
Go to appleid.apple.com
Log in using your Apple ID and password.
Scroll down to "Devices."
Click on the name of the Macbook Pro.
A small window will open; click on "Remove."
