MFiX GUI Error in MacOS

MFiX
1

I am trying to run MFiX-24.3.1, 24.4.1, and 25.3 in MacOS (v-26.1) using conda. MFiX runs using the terminal, but whenever I try to run the GUI, the following error occurs. The error lines are given below:

QObject::connect: Cannot queue arguments of type ‘QTextCursor’

(Make sure ‘QTextCursor’ is registered using qRegisterMetaType().)

QObject::setParent: Cannot set parent, new parent is in a different thread

*** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘NSWindow should only be instantiated on the main thread!’

libc++abi: terminating due to uncaught exception of type NSException

zsh: abort mfix

Can anyone help me solve this? Thank you.

Might this be the same issue?

3

Thank you for your reply. I tried this also, but it shows that “zsh: no matches found: vtk=*=*qt*”. I am not entirely sure how to fix this issue.

4

And this is what you tried: conda install vtk=*=*qt*?

5

Yes, I tried this command line. I am not sure, though, what this line is supposed to do?

This replaces the “egl” version of the VTK library with one built for "Qt”. But I’m not sure that this is the root of the problem you are having.

The message from zsh indicates that it tried to expand the ‘*’ in the command (which is not desired). Try this instead:

conda install 'vtk=*=*qt*'

If this doesn’t resolve the problem, please send us the output from conda list.
Thank you.

Thank you for replying. It didn’t work. I have uploaded the .txt file with the output “conda list” shows in the terminal.
