I have tried various methods and procedures to get Mountain Lion installed on my HP Elitebook 2570p (integrated HD4000) graphics... (note this is a laptop not a desktop...it has an LCD screen, a VGA port and a Display port)
Each time I have come across the issue that if I do not boot with the flag GraphicsEnabler=No, Then the laptop screen will go blank (black) after the initial Apple logo screen (with spinning wheel).. I have spent literally hours, trying to get the internal display to work to absolutely no avail (string injection, Chamelon etc etc)
When I do boot with GraphicsEnabler = No.... The system loads but its stuck at the 1024 x 768 resolution with no option to change it.
I see that Pandoras box 2 changlog indicates that it sets boot kernel flags for HD3000 /4000 graphics. Does this mean it should automatically detect my HD4000 and make the internal display work without all the drama I have experienced previously ? Or will i still need to edit plists etc etc?
Whilst we are on the topic...when the screen goes black I find that I have no way of rebooting the system without physically holding down the power button and chopping the power. Does anyone know of a friendlier way to reboot the system whilst it is in this state as im concerned I am gradually damaging my components shutting down this way (I must have done it about 500 times now whilst trying to get the internal HD4000 be detected).
