Connect to Cisco Console Serial Port via Mac OS X

I prefer not to have to download apps when an OS has a native option. To connect to a console from Mac OS X simply use;

/usr/bin/screen /dev/YOURTTYDEVICE 9600

If you want to log all input/output to a log file (as you should when connecting to switches/routers/firewalls) simply use the script command as follows;

/usr/bin/script /PATHTOFILE

Optionally, configure terminal to always log sessions by editing the app preferences, go to the shell options and you should have an option to run a command on startup. My command reads as;

/usr/bin/script ~/Desktop/Terminal.log
