Dear @nattaporn ,

I assume that you have followed the preliminary steps to install Flair/geoviewer on Mac under the section “Mac OsX”

I believe your error was addressed in this post

Flair on macos M4, issue with interface and geoviewer

Hello @thomas.f Since the update to tk version 8.6.15, MacPort has changed the default variant to +quartz. This is causing the compilation problem and the strange Flair appearance. To fix this, please run the following command to switch to the +x11 variant. sudo port install tk +x11 After that, please recompile geoviewer and test Flair again. Please let us know if this resolves the issue. Cheers, Luigi

Moreover, we noticed that there is an issue with MacPort installation based Python 3.13. In this case, please downgrade to a previous version (3.12 or 3.11).

Please let us know if this fix your problem.

Best regards, Luigi

Thank you for your reply.

But I still got a strange interface of flair as the same with that post.
And I already checked python version as shown in the figure…

However, I did not get the error results after I run “make install DESTDIR=/path_to_flair/” anymore.

Moreover, I’ve checked installation script follow this website (FLUKA Beginner Online Training (5-16 October 2020): FLUKA and Flair installation check script · Indico)

My result…

Can you check with Python 3.11?

In another post, Python 3.12 was reported not to work:

Flair on macOS Sequoia 15.2

Hello @luillo, Yes, I’m well. I hope you too! Your solution works of course, and gratefully appreciated as always. I took python3 back one step at a time. python312 didn’t work but python311 did. I now have Flair on my Sequoia in full glory. Cheers! mary

Thank you for your helps!
Now I can run flair with normal interface, but I still got some problem about the geometry page…

and also can’t run any file with this error.

Hello @nattaporn ,

Have you check that the geoviewer.so was created after the compilation of geoviewer?
This file is then copied in the flair folder with the command `make install DESTDIR=.

For the second issue, have you set the FLUKA path in the Flair configuration?

Hope this will help.

Cheers, Luigi
