Audio on Macbook not panning!

Currently, I'm preparing for a live show in a few weeks and I REALLY need my Macbook to be able to play audio correctly... everything is mono and it sounds horrible.

In Logic, I will pan my tracks hard left and hard right and nothing happens - it still sounds like it's coming from the middle.

Here are the things I've tried:

1. First I thought it might be the headphone output on my Focusrite Scarlett 4i4. I tested this by trying to play the audio through my monitors instead of using my headphones. Well, I had the same problem on the speakers, panning had no effect.
2. My next thought was maybe the whole interface has got some screwed up setting if it's not just the headphone out. I played around with Focusrite Control, the audio interface software, but nothing seemed to fix it. I also to connect my headphones to my Yamaha mixer instead of my Focusrite to play back the audio, but that didn't make a difference.
3. Before I actually lost my mind, I thought maybe this is my stupid DAW that got messed up. I noticed this issue in Logic and I have Ableton, so I played some audio there, but still SOL.
4. Lastly, to be confident that it's an issue with my computer's audio setting, I just looked up a Youtube video of a person giving a tutorial on panning and the sound was not moving an inch to either side of my headphones.

What the heck is going on with my computer! Like I said, I have a show coming up that I'm preparing for and I really need this resolved ASAP!!! I do all my production on my Mac Mini and have no problems with that, but when I moved things over to my Macbook, I'm having all sorts of problems. I don't even know where to start to look on my Macbook for troubleshooting this audio configuration. Can someone please help?
