I’ve now tested this on Mac.
Neither the variable nor static fonts work as expected.
However, if there’s only one variant of the font that you want you can install just the static version of that single variant and it will be the single typeface available with the “Raleway” name.
If I recall correctly from previous discussions this is a limitation or bug in the framework that LightBurn uses and has no immediately available fix. It could also be from a change in how MacOS has behaved historically. I tested this on Monterey.
