Check camera access in settings: First, ensure that the camera is not being blocked by any other applications or settings. To do this, go to System Preferences > Security & Privacy > Privacy, and ensure that the camera is enabled for the applications that need to use it.
Restart your MacBook: Sometimes a simple restart can solve the problem, so try restarting your MacBook and see if that helps.
Force Quit Applications: If any applications are using the camera, you can try force quitting them by pressing Command + Option + Esc keys on your keyboard. Then, select the application that is using the camera and click “Force Quit”.
Reset the SMC and PRAM: Resetting the System Management Controller (SMC) and Parameter Random Access Memory (PRAM) can often help solve camera issues. Instructions for resetting the SMC and PRAM can be found on Apple’s support page.
Check for updates: Ensure that your MacBook is up to date with the latest software updates, as updates can often fix camera issues.
Use Safe Mode: Try booting your MacBook in Safe Mode to see if the camera works. If it does, then it is likely that a third-party application is causing the issue. In this case, you can try uninstalling or disabling any recently installed applications.
Hardware check: If none of the above steps work, there may be a hardware issue with the camera. In this case, you can take your MacBook to an authorized service provider or contact Apple support for assistance.
In summary, there are several steps you can take to fix your MacBook camera if it’s not working. If none of the above steps work, it’s best to take it to Esmond Service Centre or contact Apple support for further assistance.
