Thank You both its working fine now.  Its going to be a late night haha

I would like to practice at night with the headphones on so I do not disturb anyone.  I usually  learn songs from Youtube.  I would like to hear my guitar and Youtube from my MacBook on my headphones which are plugged into the Helix. I am continually stopping and starting the song.  How would I hook up my MacBook to the Helix where I can hear both through my headphones?  I have  thunderbolt/HDMI/USB outputs from the MacBook.  I would like to know the best connections to do this and what I would need. Thank You.
