 = Installing a Native "Apple Silicon" GSAS-II Version on MacOS = 
 
-After something like 4 months of occasional trial and much error, I was finally able to get GSAS-II to run on a ARM Mac running MacOS 11.2.3. 
+== Conda on M1 Mac ==
 
-As I write this (6/24/21), Anaconda is not supporting ARM Macs and the wxpython version of miniforge is broken, so I had to install Python and associated packages with [https://brew.sh homebrew]. 
+(May 2022) Thanks to Billy Poon, who fixed the [https://github.com/conda-forge/wxpython-feedstock/issues/74 conda-forge/wxpython bug], conda can now be used to create a working Python for GSAS-II. Note that these instructions do not provide the subversion (svn) program that is usually needed to install GSAS-II, so until this is addressed, svn must be installed by some other method, such as homebrew (see below). 
 
-== Installing Homebrew == 
+Short instructions are below: 
+
+ 1) Download the latest version of miniforge or mambaforge (I recommend mambaforge) from https://github.com/conda-forge/miniforge/releases/latest. The file you will want will be named Mambaforge-<version>-MacOSX-arm64.sh (or Miniforge...)
+
+ 2) Install Python from the downloaded file using a command in a terminal window similar to this:
+{{{
+toby@bht21 % bash ~/Downloads/Mambaforge-4.12.0-0-MacOSX-arm64.sh
+}}}
+ (note that your file location and name may vary from this.)
+
+ 3) The installer will ask you to press Enter or space multiple times to read the license file. 
+
+      A) You will then need to agree to the terms by typing {{{yes}}}. 
+
+      B) You will then need to supply a location to install this Python. Enter a name like {{{~/py39}}}. 
+
+      C) The installer will ask for permission to add conda into your login environment. I suggest saying {{{no}}} so that this installation cannot interfere with any other installed software, but if you want to use this Python for multiple purposes, you might prefer to answer otherwise. 
+
+ 4) Initialize the Python you have just installed using this command: 
+{{{
+source ~/py39/bin/activate
+}}}
+ (note that this command will depend on the answer used in 3B above.)
+
+ 5) Install the other Python packages required by GSAS-II with this command:
+{{{
+conda install python=3.9 wxpython numpy scipy matplotlib pyopengl pillow h5py imageio -c conda-forge
+}}} 
+
+ 6) Assuming that subversion is installed, install GSAS-II using these four commands:
+
+{{{
+(base) toby@bht21 ~ % mkdir /tmp/GSASII                          
+(base) toby@bht21 ~ % cd /tmp/GSASII   
+(base) toby@bht21 GSASII % svn export https://subversion.xray.aps.anl.gov/pyGSAS/install/bootstrap.py .
+(base) toby@bht21 GSASII % python bootstrap.py 
+}}}
+ Note that if subversion is not installed and in the path, the third command will fail. This is also required for the fourth command. 
+
+== GSAS-II using Homebrew ==
+
+(June 2021) After something like 4 months of occasional trial and much error, I was finally able to get GSAS-II to run on a ARM Mac running MacOS 11.2.3. As I write this, Anaconda is not supporting ARM Macs and the wxpython version of miniforge is broken, so I had to install Python and associated packages with [https://brew.sh homebrew].
