It may be an issue with their servers when detecting 10.7.x systems. I just bought a MacMini (newest one, with Thunderbolt) yesterday, updated iTunes and all other updates it recommended yesterday and wasn't ready to update 10.7 to 10.7.1, and went to do so just now and got the same error you reported.


I also have a MBP running 10.7.1 and it too won't check for updates, same error. It seems unlikely that two different comptuers on my network both have corrupted files.


That said, a Macbook running 10.6.8 can reach the server. Also tells me my router (AirPort Extreme BaseStation) isn't blocking the connection.

Finally the struggle ends. A big thanks to Apple India support (Rep: Sandeep)


To fix this problem, you will need to setup DNS servers.


Go to System Preferences >> Network >> select your network from left pane and click on "Advanced..."


Under DNS tab, add IP addresses as 8.8.8.8 & 8.8.4.4. Once done restart the system, thats all! 🙂

Im in Delhi, runing OSX 10.7.2
And i still cant so a software update.

This is the message i get:

"Software Update can't check for updates because of a network problem."
"Software Update can’t connect to the update server. Make sure you’re connected to the Internet, and then try again."


If i run network diagnostics the net that was previously working fine, stops working, and i loose connection.
I did add the IP mentioned above.
