I have spent months saving / buying cdjs, a mixer, speakers, webcams, iMac etc with my intention to get my live stream going. I’ve been following the DJ City walkthrough on OBS. I’m at the point where I need to add the audio capture, but my 2013 iMac has no line in? I’m going from my 2000 nexus to my iMac, any help with how I do this would be very appreciated! Thanks (p.s I’m a complete tech dinosaur, an idiots guide with exact hardware, cables, ports etc would be needed so I don’t mess it up)
