For my iMac, I simply pull the courser over what I want and darken it, on top toolbar choose EDIT and then choose "Copy" and then go to the side of the screen where TextEdit lives and open it, then go back to EDIT and choose "Paste".
Then you can either print it from there or edit it any way you want. Or click on the top red dot and it will ask you if you want to save it, and what name.
It will go to whatever place you want to save it.
