title: RStudio does not launch from Anaconda
body: <p>I am running Mac OS 10.5.5 Catalina and I have installed Anaconda Navigator 1.9.12. I have been programming Python 3.7 scripts on it and everything works well.
  I am now working on a project that uses R. On the Home tab of the Anaconda Navigator I have installed RStudio using the Install button. There is now a launch button under the RStudio icon. I click on the Launch button for RStudio and on the bottom right of the window a status indicates it is launching (for a few seconds). But nothing is ever launched. The RStudio program never opens up.
  This is a new installation of Mac OS and it is a new installation of Anaconda (vintage June 10, 2020).Everything is up to date.
  What can I do to get RStudio to open up from the Anaconda Navigator?</p>
