I actually saw your complaint on the Cakewalk forums when I Googled “waveslocalserver v12”. Looks like you and I got Windows and Mac covered, respectively. 
I’m really just annoyed that it continues to eat up RAM after I quit Pro Tools, and I have to manually quit the process. I hope enough people complain and something gets done about it.
This is what my Activity Monitor looks like after I quit Pro Tools.
