Mi dispiace, non parlo italiano.
volevo sapere come si fa a cancellare mobile me im maniera definitiva...
When Aperture shows the MobileMe panel, press "Learn more".
Then open the Preferences in Aperture from the main menu bar and select "Web"
Aperture > Preferences > Web
Delete "Mobile Me" from the web "Accounts" in the left panel.
if this does not suffice, remove the "Preferences" from the User Library, see the Aperture 3 Trouble Shooting Basics on how to do this,
