    I have the latest Mac Pro using it as a server with no monitor (headless).
    This thing goes to sleep and the Energy Saver System Preference has only one
    slider for Turn Display off after 1min - Never. I have selected Never and check marked Prevent computer from sleeping automatically when the display is off, but there is no display, so it just goes to sleep.

    Anyone have a solution to get the other slider back so this computer does not go to sleep?

    Another thread suggested the solution below but the Your-Mac-Model.plist has a lot of files in it and no way of knowing which file is for my Mac. Anyone know which file I should use?

    edit "/S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Your-Mac-Model.plist



    rebuild kext cache and reboot.

    What type of server?

    IMO using a workstation instead of a dedicated server has two big negative...

    1- The cost - Especially for a simple use like a file and print server. You can get more for less money. The Mac Mini server is a nice exemple.

    2- Expendability and redundancy - Dedicated server are made to grow and adapt to the need of the enterprise. A workstation is more of a specialist for a dedicated task. Many server also include redundant component to prevent downtime, like dual PSU and controller.

    If you're okay with, might try pmset...

    pmset sleep 0
    pmset displaysleep 0

    There's a ton of options - maybe "pmset autopoweroff 0" will help too. Much more here than system preferences exposts

    Apple helped find the solution for me.

    Use the following Terminal command (with an administrator password) to prevent the computer from sleeping:

    sudo pmset -a disablesleep 1
    When the value is set to 1, all sleep functions are disabled. The Sleep item in the Apple menu is also dimmed ("grayed out").
