Hi Jetblack1492,
Congratulations on the purchase of your new Macbook Pro. It sounds like you have a hardware issue with the iSight camera, as it is not opening in more than one software application.
Here are a few initial things to try. If the issue persists, I'll include a link to our technical support team to delve into this further.
How to Troubleshoot iSight
https://support.apple.com/en-us/HT2090
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.
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.
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.
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.
