On the PR3 I have two wires hooked directly to the test track and run a USB to the computer (thats it) which I am assuming after reading is my issue, although as I said before, these are the same cables I had it set up with originally. I have never has a serial adaptor, so I am going to assume that is the solution even though it worked with these cables before. ( I have several dozen locos set up in the roster that I programmed using this cable.
The PR3 doesn't use an external USB-Serial adaptor. It's inbuilt and reports as a standard USB Modem Class device so doesn't need driver installation either.
Have you carefully followed the instructions at

in order to ensure device driver is loading correctly?
Also, if running as Stand Alone, in configuration I have the system connection set to Loconet PR3, the serial port is correct ?(cu.usbmodem1421), command station type is PR3 Stand alone programmer, conn prefix is L, connection name is Loconet.
Make 100% sure that "
cu.usbmodem1421" is the port the PR3 is currently loading at. The only easy way to do this is the looping Terminal command given at the link above:while : ;do clear;ls -lt /dev|head;i=$((i+1));echo $i;sleep 1;done
Be aware that the PR3 doesn't return a unique serial number. The consequence of this is that the?"cu.usbmodem1421" will definitely change if you plug into a different port on the Mac (the numerals are a coding for hub/port number.
I am unfamiliar with a system console log or where to access it.
Go to the JMRI Help menu and you will find the system console.

That won't help. I (and many others) have successfully run the PR3 on Mac, Windows and Linux.
With Windows the COM port number will change if you plug into a different port.
I'm wondering if it's a baud rate issue. v4.16 had issues with baud rate, fixed in v4.17.x.
Check the PR3 manual for correct lights pattern for Programmer mode. I can't look up easily now.
