I've been trying to redownload Mavericks on my Mac Pro after updating it with no success. I click the continue button to download it once more and nothing. Any ideas? As to why this is under the Macbook Pro (2010) section, I attempted to update my Macbook Pro to Mavericks and it failed half way through the installation saying the drive had an error and needed to be reformatted. It was acting very unresponsive but I was able to make a disc image of the drive after 24 hours of trying. Is my hard drive completely dead or is the file system corrupted?
