OpenGL vs. Metal?

[MDNorman]

I seem to be having a problem with the requirement for having an OpenGL 3.3 compliant GPU on my Mac when running easyMELTS. In the terminal window I get an error message
"Starting GLFW context, OpenGL 3.3
Linking program.
Validation Failed: No vertex array object bound."
The computer is a desktop circa 2021 running Sonoma (14.6). It has an M1 chip. It seems to be running Metal rather than OpenGL.
easyMELTS does launch but there seem to be some functions missing such as 'Liquidus&RedistFeOx'.
Apologies if I am missing something. Any advice appreciated.

The Validation Failed happens on all (or at least most) versions. It doesn't seemed to affect how easyMelts works.

If  'Liquidus&RedistFeOx' is missing, then make sure you have clicked save after inputting the P and T, and clicked save again after inputting the composition.
