I got my iMac yesterday. First thing I tried to do was software update. I had to do the update 5 times before it finally said the update packages weren't corrupted.
Then I tried to download Xcode. That only took 4 times before the download was ok and would install.
Now I'm trying to download Unity, and I'm on my 9th time downloading it. It either says it is corrupted or invalid checksum.
I can download a file on my PC's right now and they don't get corrupted so it doesn't seem like it's an ISP problem. Is there some setting I'd need to change in my router that could possibly be bad for my Mac? I have never owned a Mac before so I really don't know anything about it. Also, I am not using the Mac on wireless right now.
