[Ifeffit] [Ext] Larch install error on MacOS 12.2

[Jeffrey Terry]

Hi Stefan,

We recently updated our EXAFS Neo analysis package to work with the new version of Larch. 

I installed Larch using the detailed instructions on our GitHub site on a number of Macs* running OS X 12.x this weekend. 

https://github.com/laumiulun/EXAFS-Neo-Public

If you want to use the Larch GUIs, you need to take the additional step of: 

larch -m

Which puts links to the GUIs on the desktop. 

Our code calls uses larch Python routines so we have developed a fairly robust procedure for making sure larch installs correctly on all operating systems. 

Hope that helps. 

Jeff

*all M1 machines but I don’t expect it will make a difference
