Hello and welcome to Apple Support Communities, Jackson!
I understand you're unable to be seen or heard when using FaceTime from your MacBook Pro. I can understand how this situation may be frustrating, especially when trying to communicate with friends or family far away. I'd be happy to provide information that may help you out.
Start by using this article to test on another user: How to test an issue in another user account on your Mac
If another user account is already set up on your Mac, you can simply log out of your account (Apple menu > Log Out) and log in with the other account. But the best way to test is with a newly created account:
- Choose Apple menu () > System Preferences, then click Users & Groups.
- Click
, then enter an administrator name and password.
- Click the Add button (+) below the list of users.
- Complete the fields shown for a Standard or Administrator account, then click Create Account (or OK).
If you plan to test with any of the documents in your own account, make those documents available to the new account. Drag them to the Shared folder of the Users folder on your hard drive (~/Users/Shared). You can then move them to other folders after you log in as the new user.
Then log out of your account and log in with the new account:
- Choose Apple menu > Log out.
- At the login window, log in with the name and password of the new account. If you're also asked to sign in with an iCloud account or Apple ID, skip that step.
Now try to reproduce the issue in the new account. If you need to set up an email account or other account in order to test, you can do so.
If it doesn't happen in the other account, a setting in your own account may be causing the issue.
Thank you for using Apple Support Communities.
Have a great weekend!
