rr7 Posted September 13, 2013 Share Posted September 13, 2013 Hi, i'm trying out a new AIO computer, this one has a GT650m. i can install and run ML 10.8.4 in safe mode, when i boot in normal mode it never seems to get to the desktop. it doesnt crash, i still see the odd console message from os x. i'm guessing this is the gfx driver not kicking in, but i'm not sure what it expects, i heard 650m worked out the box. i'm running latest chameleon, graphics enabler=no (=yes doesnt fix it) i have attached my unlatched DSDT taken from windows, and also my ioreg taken from safe mode boot. i'm used to dealing with the intel gfx, nvidia is a new one on me. could anyone perhaps point me the right way? i'm good for making DSDT edits and editing plists etc. untouched.ioreg.zip untouched.dsl.zip Link to comment https://www.insanelymac.com/forum/topic/291837-gt650m-not-working-in-normal-boot-1084/ Share on other sites More sharing options...
rr7 Posted September 13, 2013 Author Share Posted September 13, 2013 okay, so once again something i thought was known to work actually seems to be a source of grief for some people. so maybe i'll ask a different question. what is the driver that enabled graphics acceleration for kepler cards? reason i ask is that in safe mode the frame buffer loads fine, the card is detected with the correct ram and at the right resolution. i can boot the installer in safe mode no problem. NVDAGK100Hal and NVDAResman are loaded. i'm wondering if perhaps graphics is not the problem stopping my system loading in normal mode....

styrian Posted September 14, 2013 Share Posted September 14, 2013 With by others not known hardware, you will not get support. It is a bit to play guess. On wich device do have the GT650m? Is there Intel gfx too and Optimus? Have fun!

rr7 Posted September 14, 2013 Author Share Posted September 14, 2013 It's a Lenovo B540p Ivy bridge i7 3770 and nvidia gt650m I don't think it has Optimus, the hd4000 is not visible it useable in any way.

rr7 Posted September 14, 2013 Author Share Posted September 14, 2013 IT WORKS! i was right, it wasnt the gfx in fact it was VT-d, adding dart=0 to boot strings and it works great Link to comment https://www.insanelymac.com/forum/topic/291837-gt650m-not-working-in-normal-boot-1084/#findComment-1945695 Share on other sites More sharing options...

Some others here are fighting to get M Kepler cards working. Congrats to your Thanks in advance. the only steps need to enable gfx was GraphicsEnabler=No. to boot in normal mode (not safe mode) i had to add dart=0 otherwise it would freeze.ML10.8.4 Link to comment https://www.insanelymac.com/forum/topic/291837-gt650m-not-working-in-normal-boot-1084/#findComment-1945705 Share on other sites More sharing options...
TeoTheCool Posted September 15, 2013 Share Posted September 15, 2013 Could somebody with a mobile kepler card from a laptop try this? It would be simply amazing if this small dart=0 would fix the hang at boot...
