Well i have tried to download Yosemite about 10 times now and it starts off fine but decides to time out in the 2gig range and it is getting pretty aggravating, I've rebooting and everything and nothing has changed. I know this is a problem on apples end because i also have problems downloading ipsw's for iOS devices in iTunes as well meanwhile i can download a 10gig file in 10 minutes on some half-assed site. It's honestly aggravating. Did any of you have this problem and what did you do to get around it? For ipsw's i download them from some other site that pulls it from apple.
