Setting up development environment on Mac

[brian7]

I would like to setup development environment for LPCXpresso845MAX with my Mac OSX.  I downloaded the 

MCUXpresso IDE v11.1.1 successfully and have SDK and example projects loaded and able to build.  But it is not clear to me how one connects to the 845MAX development board itself.  Does this require a tool/device?  Assuming so.  What are choices and what are quick pros/cons related to each?

Thanks

Get an LPC-Link2 (OM13054) for $20-25.
