Rekordbox 5.6 Won't Run Properly (Video Attached)

This is a continuation on my previous thread, I just couldn't post a comment for whatever reason.

For some reason I can't run 5.6 properly on my Macbook Pro 15 Retina late 2016

2.6 GHZ Intel Core i7

16 GB 2133 MHZ 

Radeon Pro 460 4096 MB

This is what happens when I run 5.6

I have my settings on medium waveform speed.
if I change it to low, it actually works, but extremely slow and laggy.

5.4.3 worked just fine.
Resolume Arena 6 works perfect with up to 5 layers blended.

It must be something with the coding in 5.5 and this new update.

HELP!!!

I can run 5.4.3 but it actually crashes every now and then. I think that bug was fixed in 5.5 but I can't run it :/
