After iSight Firmware update, still getting message to install update.

Ok.  Follow the instructions by petermacc “1. You do NOT need to open the case and remove the graphics boards.

2. What you MUST do is remove the Mini DisplayPort AND THE USB for extra screen. If you leave the USB connected it still thinks the screen is there !!

3. Run the update with the first screen’s Mini DisplayPort and USB connected. Continue through the whole update cycle until you get the ‘update completed’ pop-up. Then unplug that screen and connect the Mini Displayport and USB for the next screen and repeat the exercise.

4. Plug in both screens and reboot. Check in the ‘About this Mac’ in ‘more info’ under the USB section of hardware that when you click on the ‘Display isight’ that it shows Version 2.31 for both screens/cameras.”
