[Epic Official] FBX Import Reporting

I’m trying to apply an animation to a model imported from Maya. The import of the T-posed model immediately brings up a bunch of missing bones errors. Because of this, I’m assuming, when I attempt to drop an animation into Unreal and use it on the skeleton, my model becomes a tiny circular blob. Is there a way I can prep my rig for import into UE4? I’m on mac, so I don’t believe I can use that A.R.T. utility.

Here are the .mb and .fbx files I’m working with.
