No, it's entirely up to your Xcode setup - Xcode alone determines the target macOS version. As you will see our CRAN binaries work just fine on El Capitan (where they are built). In fact, the Release target simply uses whatever SDK your Xcode provides - it can be anything as old as 10.6, there is not restriction on the macOS version in the sources. So if you use 10.12 SDK the target will be Sierra, if you use 10.6 SDK the target will be Snow Leopard etc. - for CRAN we use 10.11 SDK to target El Capitan.
