> is the controller fully synced via Bluetooth or wired cable to the Macbook Pro?

I've tested both, and both results in the same result. By the way, I'm using iMac, but I'm pretty sure it's same for the MacBook Pro.

I've tested with PS4 controller and it's working fine.

Yes.

Haven't tested.

Yes.
