PC to Mac: Blueprints no longer function properly

I am in the process of converting a finished and packaged project from PC over onto Mac.

I am experiencing some problems with menu buttons and other simple blueprint operations that work perfect in PC, but seem to not function on Mac. When I compare the widget layouts and blueprints side by side (PC next to Mac), nothing looks like it is getting lost in translation…but something is because actions, open level jumps, and button blueprints do not work the same on Mac.

Is anyone else experiencing this and possibly know of a better way move a project from PC to Mac?

Again, the project is finished and packaged for PC without error. I am hoping there is a backend issue for Mac that I am overlooking that will allow all of the blueprint function the same on both platforms.
