Has anyone with Yosemite experience a problem/delay when logging into your Mac after it's been asleep? I have a brand new MacBook Pro (had the same problem with my white unibody MacBook) and when I wake it up from sleep mode, it takes for a while for me to login even though I see the locked screen and the prompt for the password. Sometimes, the computer goes back to sleep and I have to "wake it up" by pressing the power button. Anyone else have this problem?
