I started downloading the OSX Mavericks on my laptop (Macbook Pro Early 2011) today at around 5. The first time, the download bar on my launchpad went up to about half, but then stopped for 2 hours. I then closed it, and restarted the download. The second time, it just wouldn't move. I waited for another 2 hours and since it still hadn't downloaded it I tried another time. I'm on the 4th try now and it still seems to not be downloading. I know that my internet works since it downloaded perfectly fine on my iMac thats even older then this computer. Any ideas?
