Cannot connect to App Store since 10.8.1
Hi there,
Brand new retina MBP, running 10.8.1 (updated via the app store).
Tried accessing the App Store after the update and I'm consistently rewarded with the frustrating error message 'Cannot connect to the App Store. An internet connection is required'. My internet connection is working and I'm posting on the computer in question (The only perculiar thing is that Diablo isn't letting me sign in either - it was working earlier, I don't know if thats related)
I've been searching online for a solution for a few hours now and I've read almost every thread in this forum on the topic, to no avail.
I've turned my firewall off
I don't have an anti-virus
My 'Allow Applications' is set to Mac App Store and identified developers
I've deleted cache's and plists
I've reset my machine multiple times
I've reset my router
I've reset safari and its caches
Changed MTU size
I've changed the class 3 certificates to always trust
I've changed the class 3 certificates to system defaults
I've enabled debug mode and reset the App store
This whole situation is super frustrating for a brand new computer, I'm hoping someone can help me out.
MacBook Pro with Retina display, OS X Mountain Lion (10.8.1)
