web cam not working

Hey tonyfromgu,

Thanks for the question. I understand that you are experiencing issues with the camera on your MacBook. To troubleshoot this issue, see the following steps:

Important: Follow these instructions in order. Test the camera between steps to see if the issue is resolved.

Built-in iSight cameras

These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.

1. See if the issue is application-specific.

Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.

2. See if the issue is user-specific.

Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.

3. Find out if the computer recognizes the iSight

Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.

4. Reset SMC or PMU

Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
