I'm using RStudio 1.3.1093 (R version 4.0.3) on MacBook (macOS BigSur 11.1).
I wanted to change Editor Font (Monaco → Cica, Myrica M, or SourceHanCodeJP) on RStudio, but I couldn't. In "Editor Font" of Global Options, they didn't show up in the pop-up suggestions. I also checked out the Font Book, and these fonts were appropriately installed on my computer.
What can I do for solving this problem? Does it have something to do with updating macOS BigSur?
