DNS Servers do translation, think of them as Address Books.
When you type in www.facebook.com, your browser asks a DNS server for the IP address of Facebook. This way you won't have to remember every IP address.
Chances are, your default DNS server is not updated and therefore has invalid IP addresses for the App Store and your game server, but correct ones for other things. It could be temporary but I suggest you keep using Google DNS servers. I've been using them for years on all my machines. They are fast and constantly updated.
Are you in the US? Can you see this:
If you can and click on "View in Mac App Store" does it opne App Store?
I have the same issue.
neither of the mentioned methodes worked for me, unfortunately
No, I am not in the US
the link worked perferctly for me
the app store opens correctly
but if I try to install the app nothing happens
if I go to purchases it tells me that i need to sign in. When I click on sign in - again - nothing happens.
Strange enough on my iPad all is fine.
Many thanks for your help.
I've done everything except erase and clean install. I've sent a note to Apple so we'll see what happens there. Here's a list of what I e done already:
Connected to App Store (via MacBook Air) running 10.6.8.
Upgraded to 10.8.2 via App Store.
I went to look for updates and I get the "can't connect,etc"
So I restored back to 10.6.8 time machine backup...and verified I could connect.
Tried to upgrade again: same result.
All other wifi connections appear normal and App Store browsing is fine except in updates area.
Steps I took to resolve:
Through terminal...activated the debug menu--reset app, cleared cache
Restarted -- no change
Created admin test user account
Verified that issue persists across users
Accessed App Store updates loads normally using a different MacBook Air (connected to same network) running 10.8.2
Repaired permissions on problem volume
Verified that no firewall or parental controls are blocking anything
Added alternate DNS entries -- no change
I'm trying to avoid doing a clean install to obvious reasons. But sometimes that's what it takes.
Did you ever figure this out - I've got the same issue?
Tried the DNS thing above - no difference. I also connected to the Evernote page as rrahimi suggested - this works and opens in the App store. The App store then works OK, I can click around on Purchases etc, until I click on the Featured tab. At this point the whole internet connection drops for about 5 mins - browsing, everything is affected.
I actually have tried a full re-install (after a TM backup!) - it has made no difference - issue is the same on a clean install...
