Remove and reinstall indi library and kstars #56321
I never used Kstars on a virtual machine, but Wouter (wvreeven) uses it on a Mac as well. He would be able to give more qualified advice.
Generally, I would suggest using an RPi4 running Ubuntu MATE 20.04. I have the best experience with that constellation. Painless since I went from Ubuntu 18.04 to 20.04. Run everything on the Pi4, control it via VNC from inside the house. Just works.

I used to run KStars on a VirtualBox VM on Mac about two years ago but really haven't since (apart from occasionally compiling KStars and INDI myself and even that I don't do in a VM anymore). Apart from removing all KStars and INDI libraries and binaries I'd advice you to also remove the .indi and .local/share/kstars directories since they hold all configuration for INDI and KStars respectively.
Having said that, why not simply install KStars for Mac and run it directly without a VM?

Only thought is to see if ~/.indi/CCD_Simulator_config.xml file syntax seems to be intact and includes something like:
<newNumberVector device="CCD Simulator" name="CCD_GAIN">
