Hi Youchiuan,
I believe you installed to /anaconda3 and then got prompted for an
administrator password. Unfortunately, with the MacOS Package Installer
this is the default. But you should remove /anaconda3 and
/Users/willie/.larch (which will probably require Administrator privilege)
and then re-run the installer and explicitly select "Install only for me".
(FWIW, my understanding is that this cannot be the default). This will
install to /Users/willie/xraylarch, and I believe that this will then work.
Also, make sure you get the latest installer -- it should say "0.9.46", not
"0.9.46rc1".
