The new 2022.12 release of Rstudio desktop added a splash screen that comes up when the IDE is loading. This is super brief on my system and I'd very much like to disable what looks more like a graphical glitch than any sort of useful branding. Add no splash check by timtmok · Pull Request #12117 · rstudio/rstudio · GitHub mentions a RS_NO_SPLASH envvar, but I'm not sure how to set that for a MacOS GUI app. Attempts to put this in my shell environment have no effect and as does messing with launchctl on my Monterey system. I'm afraid this may involve plist hackery, which I'm not eager about.
Any better solutions, short of an option in RStudio itself to disable this annoyance?
