Troubleshooting
Force quitting AppleCameraAssistant and VDCAssistant can resolve the 'No camera available' error on Mac. This process releases the camera so it can be utilized again. To do this, shut down any app using the camera, open Terminal, and type or paste 'sudo killall AppleCameraAssistant' and 'sudo killall VDCAssistant' and hit enter.
Alternatively, you can use a single command: 'sudo killall AppleCameraAssistant;sudo killall VDCAssistant'. This can be a more efficient way to resolve the issue.
If the above steps don't work, you can try resetting NVRAM. This is a last resort, but it can help resolve persistent camera issues.
Force Quit Assistant

If you're experiencing issues with your Mac's camera, force quitting certain processes might be the solution.
You can try force quitting AppleCameraAssistant and VDCAssistant, two processes that support the camera within MacOS.
These processes are responsible for utilizing the camera, and if they're not functioning properly, you might see the 'No camera available' error.
To force quit them, open Terminal on your Mac and type or paste 'sudo killall AppleCameraAssistant' and hit enter.
Then, type or paste 'sudo killall VDCAssistant' and hit Enter.
Alternatively, you can use the single command 'sudo killall AppleCameraAssistant;sudo killall VDCAssistant' to achieve the same result.
This can help resolve issues where the camera is not working, even after a reboot.
It's worth noting that force quitting these processes releases them to pick up the camera again, allowing you to use FaceTime, Skype, or other video calling apps without issues.

Check Everything
So, let's get started with troubleshooting. The first thing to do is check everything with the camera. Try using another application such as iChat or PhotoBooth to see if the issue is application-specific.

Test the built-in camera in another user account to see if it's a user-specific issue. This will help you determine if the problem lies with the camera or the user account.
Check System Profiler under the USB header to see if the iSight camera is detected. This will give you an idea of whether the camera is recognized by the system.
Unplug the FireWire cable from your computer and the camera, wait for a bit, and then plug it back in. This simple step can sometimes resolve the issue.
If none of these steps work, you can try force quitting the application using the Terminal. Quit all running applications that use the camera, and then enter the following commands in the Terminal: `sudo killall VDCAssistant` and `sudo killall AppleCameraAssistant`.
This will close the camera assistant processes, and you can then try reopening the application to see if the camera works.
Preventing Issues
To prevent issues with your camera on Mac, it's a good idea to check for OS updates regularly. Apple devices update themselves, but it's not foolproof, so make a habit of checking the App Store.
Select the Apple menu icon in the top left of your MacOS and select App Store. There may or may not be an update notification already. If there's an update, install it to see if it resolves the issue.
Checking your camera permissions can also help. Open the System Preferences on your Mac and click on 'Security and Privacy.' Click on the 'Privacy' tab, then click on 'Camera' in the left side menu, and verify that the application you're trying to use has a blue checkmark next to it.
