    Mac Mini - Control Power LED
    Hi all.

    I am hoping to be able to override the control of the Mac Mini Power LED from a userspace application (if necessary, I will consider kernel space). I am familiar with other hardware/OS's, and I think it is a long shot, but I was wondering whether someone here could confirm my suspicions.

    Essentially, I want to flash the power LED when there is a Disc in the CDRom drive.

    As I say, I know it is a long shot, but of anyone could point me to a reference on the subject, or to something confirming it can't be done, then I would appreciate it. My core suspicion is that the LED is tied directly into the power management chip, and can't be controlled from the OS. I have done some research, but I am unfamiliar with the Apple documentation layouts/structures, and my searches seem somewhat ineffective. The closest I have come to the subject is:

    Long URL into Apple Developer connection

    Any references, pointers, opinions most welcome

    Thanks in advance

    It is wired into the logic board, can't do anything about it

    Thanks for the prompt response. Time to invent a plan 'B'. Perhaps a USB Controlled LED (I play with PIC uControllers as well - USB Microchip ).
