I'm trying to install OS X Yosemite from the Recovery partition. Running System (not VM): OS X 10.10.2 Parallels Desktop: 10.2.0 (28956) I did the following: Parallels: create new VM from recovery partition OS X Utilities: Reinstall OS X Message 'To download and restore OS X, your computer's eligibility will be verified with Apple.': Continue Licence Agreement: Agree I have read...: Agree Select the disk shows Mac HD and Recovery HD: choosing Mac HD and select Install Message appears 'Signing in to App Store Sign in to download from App Store: entering my working username and password (also switched to German keyboard as I have a Swiss Mac, but it's neither working with US or German keyboard) --> '@' sign in username looks a bit strange but I guess it's because the installation does not support the retina display Now a message appears, that my account is disabled or that the password is wrong or that the account is locked When I logout and login again to App Store on my real OS X it works fine Does anybody have an idea what's going on? Is this a Parallels bug? Am I doing something wrong?
