Hello
I'm running macOS v 10.15.2
I've downloaded R-3.6.2.pkg from the Oregon State CRAN site. Double-clicked and default installed that R package. I've successfully opened an R-console and run a few commands. When I type Sys.which("R") in the R Console it replies: "/usr/local/bin/R"
I'm now trying to download and install RStudio from what I assume is the official rstudio.com website through the open source link. I've chosen the DOWNLOAD RSTUDIO DESKTOP link on that page. It downloads to my download directory as seen through the apple finder app. When I double click on the RStudio-1.2.5033.dmg file absolutely nothing happens. No messages, nothing. I've run "md5 RStudio-1.2.5033.dmg" as I did with the R package and get what looks like a reasonable checksum although I don't know where to check that value for the RStudio md5. I've moved the 126.9MB RStudio-1.2.5033.dmg file to the applications directory where the R.app appears to reside. I've tried deleting and reloading the RStudio dmg file. Double clicking that file produces no response of any kind.
Does anyone have any advice for what could be the problem?
Thank you for any help you can provide.
