I have tried twice to update Topaz Photo AI and both times it has filled the hard drive on my new Mac Mini. In both cases the installation did not complete. Some kind of ML process is running that takes up ~900G of space. I had to work with Apple to find the problem and remove it before trying to reinstall the program.
Upon reinstalling the same thing happened.
