Showtext sysfonts.so image not loadable

[mar-wir]

Dear Matt,

Many thanks for such a wonderful package.

I am experiencing a problem when trying to run any of the demos provided in your package. The problem is related with the {sysfonts} package. Any suggestions would be appreciated.

See a reprex below:

HI Marco,

I'm glad you like the package. I appreciate the reprex, though it looks like this doesn't relate to lcars. A minimal reprex looks like it would just be a sysfonts/Mac OS issue. Maybe just need XQuartz? I don't have a Mac to confirm. https://github.com/yixuan/showtext/issues/13

Many thanks for the tip! XQuartz might solve it! I will let you know if it worked.
