Hello,
I am using an iMac Intel Core Duo/2Ghz 20”. Since I did the sioftware update both from my System Prefwerences and the Complete update from Apple.com Photo Booth no longer works.
When I open it all I see is a black screen. The little green light does come on but no picture. What can I do about this?
I found the info on Apple's website. I had to do a full shutdown not just a restart. It is working fine now.
