    I've been wondering if there's a way to turn on a powered off iMac and have a ILO/DRAC like level of access to an iMac or any Mac for that matter that does not have a PCI/x/e slot available?

    Something like this is available for any server/PC


    But I'm just not able to think up a solution that'd let me properly interface with the Mac.

    Any ideas?

    Boards like that tend to be vendor specific as they need to link into the motherboard / bios etc at a low level. They can't just be plugged into ANY server / pc board, as the motherboard needs to support it.

    I would certainly be very surpised if anything like these products was available for even the Mac Pro, as they would need to be connected into the EFI of the Mac Pro.

    The now discontinued xsevrve product is the only Mac that I am aware of that had any Lights Out Management capability.

    The nearest solution that I can think of that you will get is to set the Wake from Network under Energy Savings and make sure that the iMac is plugged into something like a Time Capusile or Airport Extreme so that the Bonjour Proxy works to wake up the iMac. The iMac would then be left to sleep and would wake periodically to renew the setting with the Airport Extreme or Time Capsule.

    Please note however that the iMac would need to be powered on, and simply asleep. It will not power on from cold an iMac or mini or Mac Pro.

    Only the Intel-based Xserves can be started remotely from a powered-off state, "Lights Out Management".

    From the below support document, "The LOM process is controlled by a dedicated processor. This processor works independently of the two Xeon processors in the Xserve, leaving them to focus on server tasks."

    One unreliable method mentioned in the below discussion, "of having a remotely-controllable power strip and setting the computers to restart automatically on power restoration."

    Right, I'm aware of LOM being part of the Xserve line.

    I was more seeking input on a creative or aftermarket solution that accomplishes the same level of usefulness.

    Has anyone use WOL (Wake on LAN) successfully with a fully powered off iMac? (2011 model).

    Nope, no way to do it in a turned off state. The other suggestions are as close it comes to creative/alternative solutions.

    And as you are aware, Wake on Network is only for sleep state and not cold-boot. Unless you have power management schedules set in Energy Saver to start-up/shut down at specific times.

    If there was a better way or something more sufficient, i'd be using it in my server environment but there simply isnt a great solution.
