Phil,

I know what macOS preference changes this behaviour.

In "System Preferences…”, “General” there is a property,
“Use LCD font smoothing when available” (bottom of the dialog).
If this is ticked PyQt5 text is bold in appearance.
When it is not ticked it looks normal.

But this setting does not change the output of a Qt5 C++ app.

Can you reproduce this problem now?
