R will use the available memory, but keep in mind that MacOS is still a 32-bit operating system, so 9 Gb of RAM won't be used, I don't think. R will use only one processor unless you write code specifically using mechanisms like Rmpi OR if you simply run multiple R processes simultaneously. Recompiling will not change that.
