Went to install Mavericks on my Haswell MBA, seemed to download fine, computer restarted, then i got the dreaded install failed screen. Tried restarting many times with no luck, reset the PRAM, no luck, tried repairing in disk utility and was told it couldn't be repaired. Computer was working just fine this morning, so i'm pretty confused. I've found a few threads with similar issues, but not sure what my next step should be? I have a genius bar appointment tomorrow afternoon, but honestly if they're just going to try and swap the drive that's not really an acceptable solution, even though i don't have much on the drive i care about, it's still obviously not a damaged drive so i shouldn't need to lose anything. Any tips or ideas would be great!
