Our Mac notebook just froze up while playing a game. We are unable to shut off the computer by pressing the shut down button. We have to remove the battery.

When we re-install the battery, the Apple logo appears briefly and then a dual picture, half screen with lower half flutter of the game is on the screen. We are unable to do any functions.

How do we clear this? Thank you, XXXXX XXXXX for your assistance.


What type of laptop do you have? Macbook, macbook pro, powerbook, ibook

You might need to reset the power management.

If the computer is on, turn it off.

Disconnect the AC adapter and remove the computer's battery.

Press and hold the power button for 5 seconds and then release the button.

Reconnect the battery and AC Adapter.

Press the power button to restart the computer

I would also reset the pram. To do so do the following:

Step 1: Shutdown your computer

Step 2:   Locate the following 4 keys on the keyboard: Command (Apple key) , Option, P, and R. You will need to hold these keys down simultaneously in step 3.   You must do step 3 prior to the Apple logo from appearing on the screen otherwise you must shutdown and try again.

Step 3: Turn on computer and immediately hold down the Command (Apple key ) & Option & P & R key all at the same time.   

Keep holding them down. The computer will restart and on the third time you hear a chime you can let go and your computer will start up as normal.
