Everytime I wake up my new Macbook from sleep mode, I'm forced to enter in my password twice. There's a brief flash after the first login, then I get a second login screen after which everything starts up as normal. There was a thread on this a few months ago but no one seemed to have a solution. Since this is a new Mac for me, I'm not sure if this is normal or if anyone else is seeing the same problem. How can I fix this? It's pretty annoying.
