I don't have a Mac I have window 10 and I don't have a capture card
anyway thanks for your help 😉😉
well if you're on a windows 10 you don't really need a capture card (to my knowledge). you could just use obs to record the gameplay. if you don't have a microphone configured or don't know how to enable it you could just record yourself separately and layer it over the video in post. you can do that in windows movie maker fine, if you're worried if you need video editing software. anyways just a suggestion! :)
but from what i know about capture cards they're mainly useful for consoles.
