If upgrading MacOS and have a previous installation, it is possible to update by running bootstrap.py to get the latest code and to fix permissions on the. These have been resolved in the installer as of.

There are two problems with running GSAS-II on Macs under Big Sur.

See these instructions if you want to install Python yourself or have an old MacOS version, etc. Note that the first time that GSAS-II is started you will need to confirm that access to the Terminal app will be allowed. It is possible to create an alias and move that, for example if you want access to GSAS-II app on your desktop. Note that this file cannot be moved to another folder.

Drag the GSAS-II app to the dock (optional).

Wait while the files are installed (typically a few minutes).

If you get a "Command not found" error, type bash on the line before the two commands above. Note that these commands assume you are running the default bash or zsh shell. See the expanded instructions for more details. Omit the "-b -p ~/g2full" from the command above for a more verbose installation, where you can type the install path and see the licenses. Also, you are agreeing to the Anaconda and GSAS-II licenses repeated here. Note that this installs GSAS-II into directory g2full in your home folder. Paste the two lines below in that window:Ĭurl "$g2" > /tmp/g2.sh bash /tmp/g2.sh -b -p ~/g2full If this does not solve problems, please report them.

The instructions below briefly describe how to do this, but more a expanded version of these instructions are here that show screen images and explore the most likely errors. Most people will install GSAS-II by downloading a single file that contains all needed Python packages and then launches a script that downloads the appropriate files from the GSAS-II svn server. While this is not recommended, GSAS-II can be run on older versions of OS X (even back to 10.6) but you will need to find and install older Python distributions, see the "hard way" instructions. Note that GSAS-II does not display properly in Dark Mode. The installation process on MacOS 11.0 (Big Sur) see below for more has been debugged, but little testing of the code has yet been done. The Intel version of GSAS-II seems to run ok in Rosetta on Apple Silicon (M1) CPUs getting it to run in native mode has been done, but is far from drag & drop (see wiki:MacM1Notes].

I've had the most issues with Python 3.7. So with Xcode's help, I'm currently running the following versions of Python using Homebrew and Xcode: Xcode's command-line tools provide several versions of Python that can run natively on Apple Silicon. $ brew install file Mach-O 64-bit executable x86_64 $ export PATH="/usr/local/Homebrew/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin" Additionally, not all Python libraries and packages run on Apple Silicon, so it's useful to install the Intel-emulated versions as well: Rosetta 2 is required for these versions. There are no plans to backport support to 3.7 and 3.6 which are in the security-fix-only phase of their release cycles. However, Issue 41100 indicates Python 3.7 and below will never be supported on Apple Silicon:
