I recently check out a mba in a local apple store. I tried out the bootcamp assistant, I found it has no CLOSE button will it auto start up next time after boot up? also, I did the following in Terminal.app ps -ef | grep Boot | xargs kill it turns out kill the Desktop instead of switch off bootcamp assistant. whihte screen. can cold boot fix white screen? last question: is white screen an equivalent of windows famous blue screen?
