    I´m very happy with my iMac 27 late 2013.
    The last few days it shortly blink green during boot up.
    Everything works fine, but just before the Apple-logo and user accounts appear, the whole screen turns light green for a short moment.
    I have disconnected everything and run diagnose test (D key during boot up) and no problems found.

    But why the green issue. Does anyone know ?

    Regards Lars

    There was a thread a little while ago where the screen blinked for the member and resetting the pram fixed it

    Give that a shot to see if it helps.
