Hello guys i have a nvidia gt620  2gb which perfectly works  on ml 10.8.5. I recently installed mavericks and i experienced black screen on boot. I can see desktop with generic vesa driver but i cannot find any kext to make my gpu fully operational. I recently read that nvidia series are obb on mavericks. Any ideas?

Boot with -v GraphicsEnabler=No once you booted replace the copy this kext from 10.8.5 NVIDIAGF100Hal.kext and replace it in

System/Library/Extensions/

and make sure always boot with GraphicsEnabler=No or add

<key>GraphicsEnabler</key>

<string>Yes</string>
In you OCBP.........:D

What if i had both HD 3000 and nvidia 620m on mavericks, what bootflag should I use, nvidia has 1gb ram. I dont want to use Hd 3000 for it shows 320mb only.
