Hey everyone, looking for some advice and help. I have the spider 240 combo and I'm trying to record into my macbook pro. The macbook pro I have only comes equipped with USB C inputs so I purchased the thunderbolt converter. I have the USB a to USB b cable for direct recording but my macbook isn't picking it up as an audio source and I cant record with it for some reason. Any feedback would be greatly appreciated!
