Read a lot of forums and watched a lot of videos and I think I figured it out! 

I open EOS Utility, plug my M50 into my iMac with a micro USB (one made for data transfer, such as a phone cable), then open live view mode and move it into a different window by itself. 

Next, I open OBS and add a window capture and select the live view window. I crop it and I am good to go! 

Note: You have to make sure the M50 screen is out and flipped into selfie mode, this is what keeps the camera from freezing after 30 minutes. 

Now you have a streaming camera with continuous autofocus for longer than 30 minutes, oh and without a capture card! 

I hope this is able to help someone that ran into the same issues as me!
