Added: this was discussed in focus-follows-mouse-plus-auto-raise-on-mac-os-x on SO in 2010. In short, accept it, or buy an addon: how-can-i-make-focus-follow-the-mouse-cursor.

The sequence:

  1. cut text in a browser window (mouse swipe, ⌘ C: "Edit" blinks)
  2. move the mouse to a Terminal window (cursor goes solid)
  3. click in the Terminal window -- necessary in 10.8.3, not in 10.4 ?
  4. paste, ⌘ V

works only with "click in Terminal" on my new iMac 10.8.3.
On a 10.4 iMac though, ⌘ C - move mouse - ⌘ V works without the extra click.

Has FocusFollowsMouse changed in 10.8, or is it just me ? I have

defaults write FocusFollowsMouse -string YES

defaults read | grep -i mouse -->

    "" = 1;
                    default = "Time Profile App Under Mouse";
                NSMessage = timeProfileUnderMouse;
    FocusFollowsMouse = YES;
"" =     {
    MouseButtonDivision = 55;
    MouseButtonMode = OneButton;
    MouseHorizontalScroll = 1;
    MouseMomentumScroll = 1;
    MouseTwoFingerDoubleTapGesture = 3;
    MouseTwoFingerHorizSwipeGesture = 2;
    MouseVerticalScroll = 1;
    USBMouseStopsTrackpad = 0;
"" =     {

If it matters, the mouse is a cable mouse, TERM = vt100.

FWIW, Terminal behaves the same way for me in 10.8, and iTerm 2 also requires clicking the window first. – ؘؘؘؘ May 1 '13 at 10:23
I don't recall FocusFollowsMouse sending Command keys to the terminal in previous versions. Command keys are usually only sent to the frontmost application, even if a background window has keyboard focus for normal input. – Chris Page Jun 10 '13 at 1:32
Note that your defaults command is incorrect: replace -string with -bool (although some applications will figure out that the string "YES" should be treated like boolean YES, you must not rely on it). – Chris Page Jun 10 '13 at 1:33
