Hi, I just booted up my iMac and rather than the chime it started with a black screen with the apple logo and wanted my password (I have FV enabled). I entered the password where it took me to the screen you get when waking from sleep and had to enter my password again and the computer came back on like normal. I'm sure I shut it down properly but the way it came on suggests this is not the case. What I'm confused about is the entering of my password twice. This doesn't sound like a malicious program or anything? I'll be really grateful for any help! Thanks!
