Instead of the default download, you may find better suited downloads for your platform under the folder containing the latest release:

http://sourceforge.net/projects/pymca/files/pymca/PyMca5.9.6/


Notes:
See the changes section below for new features.

Tutorials can be found at:

http://pymca.sourceforge.net/documentation.html

Ready to use binaries for:

- Windows 64 bit: File pymca5.9.6-win64.exe

- MacOS X:  File PyMca5.9.6.dmg

For MacOS users, once the program installed, it might be necessary to execute from the terminal the command

sudo xattr -cr /Applications/PyMca.app

to be able to execute the program by double-clicking its icon. Alternatively it also works from the terminal by typing:

/Applications/PyMca.app/Contents/MacOS/PyMcaMain

Users of other platforms should either:

- Build from the source code.
- Use PyMca as supplied by your linux distribution.
- Install PyMca in a conda environment https://anaconda.org/conda-forge/pymca 

PyMca can also be installed from PyPI. For that just 'pip install pymca'

The mimimal dependencies are PyQt5 or PyQt6 or PySide6, numpy, fisx, h5py and matplotlib.
