Installation on Apple Silicon (M1/M2)

[ZryletTC]

Sorry if this is something that you're already aware of/have addressed but I had issues following the installation guidelines today due to being on an Apple Silicon machine and couldn't find anything about it being previously reported.

Instead of the instructions listed on your website:

conda create --name=pdfgui2 python=3.9
conda activate pdfgui2
conda install -c conda-forge diffpy.pdfgui

I had to run CONDA_SUBDIR=osx-64 conda create -n pdfgui2 python=3.9 diffpy.pdfgui -c conda-forge

I was hoping a note could be added to the website for future users with Apple Silicon chips, or better yet, the package could be built for osx-arm64.

This was a lifesaver for me – tried multiple ways always getting an error on the install line until a colleague pointed me to this. Thank you!

spoke too soon. when i got into the program, trying to run a fit, plot a fit, or even trying to copy a result value returned this:
