I'm away from computer but I would create a variable called stopTimer

Then use the get block to get msg stoptimer and set your variable to its value

Then you can use the if block to test if it equals stop

Click on an empty area of the screen. At top left of screen you should see the apple and next to it `Finder` and then `File`. Click on `File` and open a `New Finder Window`. Look at the left sidebar for `Applications' and inside that folder for 'Utilities`. In there you should fond an icon for Terminal. Click on it,

You will find the directions for installing npm on the Mac there.
