My iMac is running OS X

1- My Safari application will not open Minecraft.net; it gives a message saying "Safari can't Open the Page". This message appears on most pages. To clarify, it isn't a pop-up. It is a blank page with the message displayed.

2- Since I cannot make it to Minecraft.net, I have to go onto a different computer, download it onto a USB and drag it onto the Mac desktop. I open up Minecraft.dmg and it starts loading the launcher. IT DOESN'T GO ANY FURTHER. It trys to make some download of a file but it times out.

Whoever is looking at this can you PLEASE help me? I would REALLY appreciate that. Thanks!

I will provide the Error Log in the Attachments, Please look.
