LyX Version 2.3.1 not showing bold on screen

[Paola Manzini]

Hi All,

using LyX 2.3.1 on a MacBook Pro, Mac OS version 10.14 Mojave: bold fonts do 
not show on screen when editing. The documents does compile correctly. I 
haven’t seen this bug reported, so here I go. I had the same problem on Mac OS 
High Sierra.

Thanks,
Paola
