Allen_N Posted February 19, 2014 Share Posted February 19, 2014 I picked up this machine during the week and I reckoned that it would make a great 22" iHac. Specs are Intel C2D / Nvidia 8400GT / 22" LCD with 1680*1050 resolution. The problem I am running into is the screen going black when window manager starts. The only thing I could get to boot was the iFail ml (distro) installer. Installing it resulted in the same issue. However distros IMO are not the right way, so I would like a vanilla installation GPU details are as follows: Geforce 8400 GT - (10DE 0426) 128MB VRAM Any pointers on how I can get past this hurdle?

Administrators Hervé Posted February 19, 2014 Administrators Share Posted February 19, 2014 Which version of OS X are you trying to install? Try and boot with Chameleon flag -v. If you see the nVidia 8400GT reported in the 1st few lines of the startup, then GraphicsEnabler option is enabled. You should then try to boot with option GraphicsEnabler=No. If you do not see the graphics card reported, try with boot option GraphicsEnabler=Yes (but that may also require additional option PciRoot=). You may require a patched DSDT to get that GPU supported, but it should not be a problem as the nVidia 8400 family is supported by OS X and it is fitted to many models we support here (eg: D630 or D830 that have the mobile version of the chip).
