As a Mac fan myself, I have lots of information to help. In fact,
both Wayne and I here at Elecraft are primarily Mac users (but we use
Windows and other systems as well). Connecting a Mac to the K2 is
very easy, involving only three wires of the Mini-Din 8 bundle. The
Mini-Din 8 appeared on all Macs from the Mac Plus until Async serial
was dropped in favor of USB around the year 2000. The connectors are
still used in several USB-Serial adapters, most notably the Keyspan
dual-serial devices.
I usually fabricate a serial cable by taking an existing Mini Din-8
to Mini Din-8 cable and cutting it in half, then installing a male
DE-9 with hood onto the cut end of the cable. You will need to make
the following connections:
Mini Din-8 DE9M (most folks call it a DB9M)
5 2
3 3
4 5
Identifying the Mini Din-8 pins can be difficult. The pins you need
are in the middle row. The gap between pins 4 and 5 is noticeably
larger than that between pins 3 and 4. You don't need to connect any
other leads from the Mini Din-8 - in fact doing so could cause
problems in the K2.
As for Mac software and information, there is a wealth of info at the
Mac Ham radio web site:
http://www.machamradio.com/
Most users have upgraded to MacOS X systems, but there are still
quite a few folks still using older systems. Much f the older
software still works just fine, and is there just for the asking or
downloading!
Good luck - if you need anything else, just ask.

RS-232 is a protocol.
DB-9 is a connector (so is your mini-DIN).
RS-232 via an RJ45 is still RS-232 (as it would be over 4 pair of
field-telephone wire).
I did not know that. Thanks for the info.
Sounds like you are good to go!
Will do.
