I have 0 problems with lich in parallels other than the installation, I had to install the previous package to 5.7 and then update it 5.7 because the ruby version 3.2.2 doesn't work (at the time.. maybe yet?) but other than that no issues.
I mean not everyone wants to pay for parallels just to play their 40 year old text game but it's just a quick .02 if they're still having issues.
