Hi Matt, Thanks for the help. Not your trouble. This one was thanks to Apple. I strongly caution anyone who is upgrading. It took out a lot of software. GSAS-II was a nightmare to get working again. I can confirm that the removal of pyepics allows larch to run on the command line. However, I now have a different problem. If I run either larch -m or sudo larch -m, I get the following error. Warning: could not create shortcut to /Users/jterry/anaconda3/bin/larch Warning: could not create shortcut to /Users/jterry/anaconda3/bin/larch --wxgui Warning: could not create shortcut to /Users/jterry/anaconda3/bin/xas_viewer Warning: could not create shortcut to /Users/jterry/anaconda3/bin/gse_mapviewer Warning: could not create shortcut to /Users/jterry/anaconda3/bin/gse_dtcorrect Warning: could not create shortcut to /Users/jterry/anaconda3/bin/xrfdisplay Warning: could not create shortcut to /Users/jterry/anaconda3/bin/dioptas_larch Warning: could not create shortcut to /Users/jterry/anaconda3/bin/xrd2d_viewer Warning: could not create shortcut to /Users/jterry/anaconda3/bin/xrd1d_viewer I don’t know if Apple has munged up the permissions to writing to the Desktop which is where the old Larch directory was placed or if something else has gone wrong. All the files are located in the anaconda/bin directory. Larch just appears unable to create the folder on the desktop or the shortcuts. Thanks, Jeff

Sorry for the trouble, and yes I can confirm this trouble. It's actually not specific to MacOS version. It appears to be related to Python 3.7.6 (yes, 3.7.5 and 3.8.0 were OK) breaking pyepics on all systems. Unfortunately, a "conda update" will now install Python 3.7.6.
For now, I would suggest just removing pyepics from the installation (it's not really necessary for Larch functionality) with
rm -rf /Users/jterry/anaconda3/lib/python3.7/site-packages/epics/
I think that should work, at least until pyepics gets fixed.

Now whether I install larch from source or by using conda, I get the following error:

I think that line 11 is: load_entry_point('xraylarch==0.9.46', 'console_scripts', 'larch')()
Any ideas on how to address this issue?
Thanks,
Jeff
