Taudecay problem in Mac

This should be fixed in the next version 3.4.1 (which should be released soon in principle)
and is working in our Long Term Stable version (2.9.10)

Thanks for the bug report,

Olivier

Thank you Olivier for the quick reply, I look forward to the new version.

However, after this post I went and downloaded MG v2.9.10 and tried to simply launch it. Same machine, no changes, I get this error. I also get it on a different Mac machine.

Using default text editor "vi". Set another one in ./input/mg5_configuration.txt
