PLEASE will someone show me how to turn off autofocus on my Logitech Streamcam in OBS from my MacBook Pro. I've watched umpteen videos on YouTube and when they all click Properties, a whole new world opens up on a PC for them including a box to un-tick Autofocus but I only get Device and Preset on the Mac and bugger all else! I've checked everywhere under Settings. I've downloaded the Logi Capture app but i don't know why cos I want to record and stream using OBS and I can't see that the app links to OBS in anyway. I'd REALLY appreciate some help.
