Long time qgis mac user. I find with qgis 3.4, it will not change fonts within the Layout text box, nor will it show ESRI North arrows when I choose that font in a text box.
When I deleted 3.4 and reloaded 3.2 Bonn all the fonts are working as before. Has this been noted and been fixed? I cant use 3.4 at this point.
QGIS 3 is a vast improvement over 2.18. Congratulations to the development team.
