Hi @JohnnyC,
Do you have the same problem (flair crashes while opening geoviewer)
with the macports installation as well - or do you encounter a different issue?
In case of the same issue, could you please follow the instructions here and let us know?
In case you see different problems, could you please be more specific?
(i.e. not able to install? run? and error that appears in the terminal)
Thanks,
Thanos
