My wife's three week new macbook air is now stuck in the half apple screen forever. I think when she was asked to update the software, she clicked install, but closed the lip as she needs to go. Now the macbook air is bricked. I can't get pass the screen with the apple on it even if after I shut it down and restart. Now it may not be that bad a problem if she had backed up her important files. As they are not backed up. If it is a windows laptop, I could easily swap out the hard drive with an enclosure and backed up the file and do a reinstall. Can any one tell me what should I do now. I can not risk losing the data on the disk.
