Reinstalling the application may fix this problem. This means, as far as I understand that Qt5 cannot find its "plugins" directory. But, if I point to some Qt5.12 plugins I had installed myself, it still fails: CCP4MGs-MBP:ccp4i2-pyside2 stuart$ QT_QPA_PLATFORM_PLUGIN_PATH=~/Qt/5.12.3/clang_64/plugins/ ccp4-python testPySide.py qt.qpa.plugin: Could not load the Qt platform plugin "cocoa" in "/Users/stuart/Qt/5.12.3/clang_64/plugins/" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: cocoa, minimal, offscreen, webgl. Abort trap: 6 This leaves me confused. My plugins/platform directory does indeed seem to contain the 4 plugins listed. I do not know why this fails, I guess my plugins are incompatible with your Frameworks. So, I assume your qt5 plugins need to be in the bundle (this would be true anyway). The qt4 ones are in the bundle. Closer.
