I am using my MAC book as principal machine (i was a Windows user). Every day i need a ssh connection with servers to do admin tasks.
On windows i use Mobaxterm the best tool i used to do things using ssh. My favorite feature is X Window to use graphical interfaces via x11 forward.
There is no Mobaxterm for Mac, so i installed XQuartz http://xquartz.macosforge.org/landing/.
To use the X Window start your connection (after setup XQuartz) using ssh -X user@server
