Yes, I'm using an iMac, and yes, they daisy chain just like the K3/P3. I have VMware shut down. I went so far as to unplug the Serial-USB cable going into the iMac and plugged back in. The iMac asked where to connect it to. I told it the Mac. Still no joy. The KX3 by itself connects fine, the PX3 is out to lunch.

I unchained 'em and got the same result - iMac cannot see the PX3.

Tried using the cable that my K3/P3 use - no joy there, either.

Brought up the PX3 menu to power-on/reset. Again, no change.

I called Elecraft - all lines busy. So I sent an email to support. Still waiting for a reply......
