Default korean font issue in Mac RStudio

Good morning. R studio is so good and I love it.
At some point, the Korean font in Mac R studio was changed to a "serif" style (blue square in the attached screenshot).
Many Koreans think that the "sans serif" style goes better with the English font, Lucida grande.
Please consider returning the Korean font in R studio to a sans serif family.
It will save people like me who are always looking at statistics programs.
