Hi,
In MAC OS X, I m not able to copy the entire Console output so that i can paste it into a file for analysis n debugging.
Is there any way to send the output to a file instead of console?
or at least any way to copy entire console output instead of selecting individual sections and copying?
instead, nope
but in addition. you can hook up the error handling delegate if you want and write it yourself to a file
Ok got it 
Thanks Dreamora.
yes that using .NET is ever possible, but wanted to know if any provision from Unity IDE. which i got finally – Editor log
You can use OS X’s Console.app and look in the Unity section under ~/Library/Logs, or click on Open Editor Log in Unity’s console. Everything is always logged to a file.

yup Eric got that
but still the file is not auto-updating once i edit and remove old data!
Anyways, restarting Unity makes it work again!!
