Sorry, but we will only be supporting macOS 10.11 and above with RStudio v1.2. 10.9 (Mavericks) is quite old now; I'd recommend updating your OS if at all possible.

OK – but you should change your web page that states for the Desktop Version Installers:

"RStudio 1.2.981 - Mac OS X 10.6+ (64-bit)"

This misled me...

We'll take care of that when we publish the next Preview release; thanks for spotting that.
