Ted (VE3TRQ), I found your posting outlining how to do this very helpful - THANK YOU!  But, because most of this is new to me, I have a number of questions.  First, the software that I have loaded on my Mac includes dogparkSDR, Fldigi and Loopback.  I started through the steps that you outlined and am stuck on step 2 (xDax - where do I get this software) and  step 3 (rigcntl - where do I get this software).   Also, I'm unclear as to how the software will communicate with the radio - will it require any interface cables or will this all be done wirelessly through dogpark SDR?  Thanks for helping!!

You will need to get xDax and xCat from Mario, DL3LSM, at https://dl3lsm.blogspot.de/p/download..., then use them to expose devices for your digital apps. xDax will connect to one side of the Loopback device for TX and Rx.

RigCtlD is used by some digital apps, and is used if the app needs it. HamLib implements it, so if you don't use the HamLib libraries, you won't need to set that up,

All communication to the radio is done by xDax and xCat through your Ethernet network. dogparkSDR will run along side xDax and xCat, and does not need them. In fact, with my 6600M, I usually don't run dogparkSDR when I am home (which is pretty much all of the time). I just leave the 6600M GUI interface connected to the radio instead of dogparkSDR. Once your digital app is connected to the services exposed by Loopback and xDax/xCat, you don't need anything else.

Making progress, Ted!  Got everything working but for some reason, both Dax and Cat seem to drop every few minutes.  Have to quit the application and start it again - then it runs fine for a few minutes and drops again.  Any thoughts?

One thing that I noticed is that if I bring up both Dax and Cat without FLdigi, the connection with the radio does not drop after a few minutes (has been up for over 15 minutes already).  So, I'm concluding that something in FLdigi is triggering the drop.  Perhaps there is a parameter that I haven't set correctly?

Well, so much for that theory - dropped after 4 minutes with nothing (no FLdigi) connected.  I wonder if something is related to smartLink.  It's been taking progressively longer to establish a connection with the radio (use to take a few seconds - that has increased at times to a minute or more for both Dax and Cat.

Are you local or remote? Smartlink isn't needed for local - the radio broadcasts on the local network, so various pieces of software (including SSDR, dogparkSDR, and Dax/Cat) will find it.
Verify you have no network issues - routers, switches, access points, wiring, etc. Having network drops will cause disconnects - which will be quicker and more frequent when you are passing more data.
Good luck troubleshooting :-) I was successful with 5G WiFi, but NOT 2.4G.
