Sandbox creation failed

[daniesy]

Hello everyone!

I get Sandbox creation failed whenever i try to open the new apps like Reminders or Gamecenter. Any idea why?

Fixed by reinstalling Essentials.pkg

I'm having the same problem.

Where can I find essentials.pckg?

In the installer? In which folder? I'm trying to find it but I can't.

Thanks in advance
