On Mac it sometimes works and other times leads to the spinning wheel. I also have tried using the CMD-Return combination to run the lines with the same results. 

Spinning wheel means that R has entered C code that is not interruptible. It's no different from the Windows version except that Windows GUI doesn't even have the indicator.

If you are running a script (interpreted code), you can interrupt it with <Esc> or the Stop button and there is no spinning wheel.
