This is not a huge problem of course since I can still read the text. However I would like to make it darker. I didn’t manage to find a corresponding setting anywhere in KiCad. Maybe I can change it somehow else, e.g. by editing some text config?
I’m pretty sure that binary that is currently in testing will become 5.0.2 release, you can get it ahead of time. http://downloads.kicad.org/osx/testing/
make sure to get 10_14 variant, that one is for Mojave.
