I've got a new SSD for my wifes Macbook Pro (2011, 13"). I've installed the drive and am using the OS recovery to get Lion on there. Later I'll upgrade to Mavericks, then use time machine to restore her files. I've used my own Apple ID to login while performing the OS restore. Am I ok later to sign out of mine and back in with hers after the Mavericks upgrade? Or are there any hoops to go through first?
