Wavelab spitting with dante

I have a Dante set up with WaveLab Pro 9 running on both platforms, PC and Mac. No problems on the PC. On the Mac I get drop outs on playback every couple of minutes. All updates are correct, Dante, RedNet, MAC OS, and everything states locked and green. I diagnosed this with Audinate and we found no issues with the system. It works fine with other software - Logic, Tidal streaming, Davinci Resolve… (Pro Tools runs off the HDX card). Only Wavelab is having this issue. Anyone else see this? How are you setting up with a dante system on Mac? Hopefully no one suggests going beyond WL 9.5 as I have VPI plugin’s that need to remain at WL 9. They are not compatible any higher. Thank you
