[teedzay]

Tried installing Mavericks today and get a black screen after the apple logo. Used the boot flags such as -x, -v, GraphicsEnabler=Yes PCIRootUID=1 and still black screen.

i have the ff. setup
a. GeForce 9800 GTX+ 512MB 256-bit GDDR3 PCI Express 2.0 x16
b. Intel Core 2 Quad 3.0GHz LGA 775 95W Quad-Core Processor
c. GIGABYTE GA-EP45-UD3P Intel P45 ATX Intel Motherboard

can anyone help me on this? Thanks!

I had an 8800 GT (same G92 chipset as the 9800). Ran into the same exact problem as you. Perhaps Mavericks removed the G92 drivers?

Went to Fry's and bought a 650 TI Boost. Works like a charm.

So you're saying that this is just a graphics card issue and replacing it to a new one will correct the problem?

Have you seen this ? Maybe there is a solution for you... and i don't think that this is only a Grphicscard problem, as there are many reports of 8800GT and also 9800GT gfx cards working in Mavericks

Tried everything and still getting the same problem which is the black screen after the apple logo. last resort would really have to be upgrading to a new graphics card.

I have exactly the same problem with my 8800GT. (Previously running 10.7 with no problems). If any 1 has any idea how to fix it, that would be great, since I cant replace my card for now :/.

Yup, problems on a P5K Premium Wifi/AP with 9800GTX+ as well...

Got a tip from here:

GTS 250 also has the G92 chip.

I was using a DVI->HDMI adapter, and a HDMI cable to my monitor. Replaced it with a DVI cable, used "GraphicsEnabler=Yes" on boot, and could easily boot to the installer

I solved this issue on my parents' build by using "GraphicsEnabler=Yes, IGPEnabler=No" at boot. Just GraphicsEnabler=Yes was not enough to do the trick for me. Hope this helps someone else in the same situation.
