McStas Installation on Mac OS X

The distribution packages for McStas may be downloaded via http://downloads.mcstas.org

Installing McStas 2.4 and later on Mac OS X

  1. Download the mcstas-2.4-macOS.tar.gz archive
  2. Unpack it and open the mcstas-2.4 folder in Finder
  3. Drag the McStas-2.4.app and the McStas-2.4-environment.command to your /Applications folder
  4. Right-click and chose "open" on the Check-PY-dependencies.command script
  5. PLEASE follow the on-screen instructions - and repeat opening the script until after you have been offered to take ownership of /usr/local!
  6. You should further Place this configuration file in your /Applications//McStas-2.4.app/Contents/Resources/mcstas/2.4/tools/Python/mccodelib/ folder (hint: run 'open $MCSTAS' from the terminal and you should get a finder window in /Applications//McStas-2.4.app/Contents/Resources/mcstas/2.4/)
  7. Optionally also run the Check-PL-dependencies.command script if you want to have access to the Perl tools
Once installed you may open the McStas-2.4.app from /Applications. (On the first run, please right-click and choose "open"). Depending on your version of Mac OS, you may have to adjust security settings to allow "Apps from anywhere".

To use your newly installed McStas from the terminal, either

  • Use the McStas-2.4-environment.command shortcut from /Applications
  • Issue the mcstas-2.4-environment command in a new terminal
  • Use the File->Set as default menu point in the Python mcgui

Please report any trouble in using these instructions to mcstas-users@mcstas.org.
