V-Fonts default master must be Regular (for MacOS apps: TextEdit, Pages, Key..)

On Mac OS (10.15 and below) native apps: TextEdit, Pages, Numbers and Keynote, the default weight gets intermingled with another weight, if default is not set to Regular.


This is unfortunate, since not every variable font has a master on the Regular weight.

We’ve locked at a variety of open source and commercial variable fonts on the marked. Only when Regular is set as default, all works fine. After a lot of testing, the conclusion is, that there is no way to fix this on the font side.

Luckily it appears to be resolved in MacOS Big Sur.
