Has anyone else figured this out? I'm getting it on every machine I upgrade and I have about 18 more to go and would like to fix it.
These are brand new iMac's shipped with Mountain Lion. I turn them on and the third screen asks if you want to transfer items from a backup or another Mac. I choose another Mac. Then use Migration Assistant on the users old machine (running Snow Leopard 10.6.8) and then let it transfer all of their files.
At just about the end of the transfer the new Mac pops up this error and waits until an action is taken. I've tried every password it could have been on the previous users machine to no avial. The only option appears to be hitting cancel and movi ng on but I'd like to know what is breaking when this happens becase the machines exhibit a strange spinning wheel hang when logging in afterwards?
Here's a screen shot of the new iMac and the problem:
Thanks!
