Brand new iMac 5k and my Lightroom profiles are way off.

I have not tried my other printers this morning but when I fired up my P8000 (dye sub) the profiles were not even close.
Reds, browns and purple all over the map. Wasted about $75 worth of metal before it dawned on me that it may be an issue with Mojave. (10.14.6)
I pulled my 10 yo Mac Pro out of the closet and hooked it up again so I could print these metals.
Any fixes, thoughts?
Hope this was not $5600 down the drain. Printing is my business so this has to work..

I have refillable carts in all my printers so I have been staying away from any kind of updates.
In this situation nothing works so here goes. Updating the driver on the 9900 and P8000 as we speak.
Sure hope my refillable chips do not get locked out.
