Matplotlib 3 in Mac OS X

In the case of using matplotlib 3 under Mac OS X (installations starting in 2019), in order to avoid a potential error associated to the use of the libc++abi.dylib library by the TkAgg backend, we recommend you to add the following line to the $HOME/.matplotlib/matplotlibrc file (you should create the file if this does not exist):

(megara) $ more $HOME/.matplotlib/matplotlibrc
backend: TkAgg

Note that TkAgg is the default backend in Mac OS X. If you want to use alternative ones they also need to be installed, or course.

Compiling in Mac OS X 10.10 or later

Should the user be insterested in compiling part of the software on their own, we note that in the case of the distribution of Mac OS X 10.10 or later they should include the following environment variable in the $HOME/.bashrc shell configuration file:

(megara) $ more $HOME/.bashrc
export MACOSX_DEPLOYMENT_TARGET=10.9

Bash shell

Bash shell is the default shell for using the MEGARA DRP and the megara-tools. Please, be aware that starting on Mac OS X 10.15 “Catalina” the default shell is zsh. Tests on zsh have not yet been performed to ensure its compatibility MEGARA DRP and megara-tools.
