Taking a screen shot or printing to a file from Ar

This should be a really easy question to answer. How can I take a screen shot of a lengthy output or to print the serial monitor output to a file on a MAC using the arduino IDE. the IDE does not like copying and pasting

I have tried using terminal and the screen command, I tried to divert the output etc etc. Can someone provide a step by step set of instruction. It is not possible to get proper help until I can send the info

regards
Max
 
On Mac, the sequence is ALT+A, ALT+V and ALT+P in the destination - sometimes it is CTRL+A, CTRL+V, CTRL+P
If that does not work, there are alternative serial monitors even for Mac:
