I am having a problem getting RStudio to install properly on my Mac running OS X 10.15. I downloaded the RStudio-1.2.5033.dmg file for Mac OS 10.12+ and ran the install. When I open the RStudio application I am missing the File toolbar. I have gone to the Workspace Panes > Pane Layout section and tried different settings for General, Appearance, Pane Layout, etc., but I cannot find a setting to show the File toolbar. I have deleted RStudio and reinstalled 3 times and always get the same default application setup without the file toolbar. The image below shows the (lack of) the File toolbar. I have searched here and have not found a similar issue discussed. Any help is greatly appreciated. Thank you!
