Need help getting a program running on a KL25z

I am trying to get started with a FRDM-KL25Z. I have downloaded the quick start guide, and am racing document FRDM-KL25Z Quick Start Guide (Rev 1.0).pdf. Looking at Page 2 of 2 — Introduction to OpenSDA. I am connecting it to a MacBook Pro.


In order to see the device on the Mac, I have to hold down the board's start button while inserting the connection.  Otherwise, the device does not show up on the Mac.  Even with that, it does not show up in Finder, but only on the desktop.  It is called “BOOTLOADER”  


When I drag one of the .srec files to the boot loader directory, nothing happens.  I tried the blinky_blue.srec file and blinkey_red.srec files and others, but nothing happens. 


Since the boot loader shows up as only its own icon on the Mac desktop, I am unable to properly eject it before disconnecting, and I always get an error message when disconnecting.


What am I doing wrong, and how can I get this going so I can load a program and run it?
