Just bought MBPr and cannot connect to appstore Whenever I try to connect to app store I got this error:



I tried everything I could find in internet, but always the same problem.

OSX: Yosemite
Model: MBPr 15 mid-2014

Any help?
Check the date and time / timezone. If it's incorrect you won't be able to connect to the App Store (or much else for that matter.)
