Hi I pressed by mistake the command and power button simultaneously. A black screen with a cursor in the left upper corner appeared. It stays like this a while before it goes back to normal. How can I repair this mistake?
Thank you
 
That just goes to the debugger (if it's installed). Since it's back to normal, what are you worried about?
 
What to do

The problem is that I have installed the bootcamp. Now when I press option and power to chose the drive this blank page appears and stays for a very long time. And then it goes to a black page (MS DOS like) asking to chose the windows to start however it freezes and even if I press esc, enter or tab nothing happens it stays like that until I turn of the computer manually from the power button. What I wish to know is have I messed up by pressing command and power button? And how can I take that off to be able to start fast the mac and the windows.
Thank you for your reply.
