Hey @jacobziegler9, welcome to the community and thanks for your post! I've taken this screenshot from a Windows PC, but I believe this should work the same on Mac. In the bottom right corner (to the right of your volume control), you should see a double arrow icon like in the attached screenshot. That's the button you click to get into full screen mode.
Let me know if you have any issues!
