    Next steps:

    Purchased El Capitan, installed it
    Downloaded MacPostFactor+2.0.1+Release.dmg
    Downloaded Macosxbootloader v3.1 from piker-alpha.github.io


    Should I stop now or upgrade from USB into a second partition?

    I have the same machine, I haven’t put El Capitan on it since the graphics card does not support hardware acceleration, rendering the machine virtually unusable.

    Mountain lion works on it like a charm, and is the latest OS I would recommend for this setup.

    Apple AppStore refuses to download Mountain Lion. At option boot, the system refuses to install from a USB that was created from an image downloaded from a MacBookPro.
    If you have a recipe or suggestions for altering a Mountain Lion install image (plist editing, perhaps?) I would very much appreciate a link to the 'how-to'.
    Best, - trifle

    You have to place the ML installer in your application folder, then open Macpostfactor and continue the installation. It will handle it from there :) for more info, see: https://osxhackers.net/macpostfactor/
