I am using MacBook, and I would like to use my webcam during the meeting session
Hi @jamesnotti, welcome to the community.
Sharing your webcam in a GoToMeeting is easy if you have a USB or built-in webcam, and as you join the meeting you should see a preview screen so you can test it and see what it will look like before you share it.
Please note that the meeting organizer does have the option to disable webcam sharing.
