Vim mouse cursor moves iTerm position iMac

How to move the cursor in Vim using the mouse (Mac OSX)
Since I moved to an iMac running OSX, when using vim (via iTerm) I had a problem moving the cursor position n iTerm to the current position of the mouse cursor.

I changed my vimrc to add. This enabled moving the cursor position with the mouse, but unfortunately it broke the ability to use multiple copy buffers. That was too much to lose for easy cursor movement.

The solution in the end was to remove the set mouse command completely and instead use: which moves the iTerm cursor to the same position as the mouse cursor.
