Note: This is very poorly written. I am very tired right now, so this is going to be a bit of a mess, hopefully it will still be helpful however.
Boy oh boy, was this a straight pain in the ass. I'm going to start off by saying this- I was very, very close to quitting, and just reinstalling Windows 10, but I didn't. I tried a few more things and got it working, thankfully. Now I can enjoy OS X and Win10 in one pc. Here's my build (Everything that matters) AMD FX 8350 Black Edition @4.0GHz ASROCK 970 Extreme4 Corsair Vengance: 16GB @1600MHz EVGA Nvidia GTX 770 SC (2GB) Some random crap hard drive
I used uh...something. Something popular, something that you def know if if you're here, but I can't say, there was no way in hell that I was going to be patient enough to figure out what to do with standard Yosemite.
This isn't an in depth tutorial, but I can give you some pointers.
What I did on my mobo:
Disabled EVERY AMD hardware acceleration feature Changed my HDD from IDE to AHCI Changed both Overclock features to manual, but I didn't touch them
Installing OSX was easy. I loaded it up with the following flags /amd64 -v npci=0x3000 GraphicsEnabler=No
I disabled all laptop stuff, I didn't install a bootloader, I disabled audio and network kexts, I actually forgot to set the flags in the installer but it didn't matter, and I installed (I may be forgetting things, I probably should have written what I did down, but I didn't think it'd end up working in the first place)
Once installed I set it up and booted into safe mode since I was getting a graphics error on normal boots that made it impossible to do anything on the machine.
On another computer I downloaded Multibeast, Nvidia display drivers, the RealtekRTL8111 kext, Kext Utility, and my mouse driver. I installed everything, (DSDT Free, or whatever the bottom dsdt option in multibeast in, no bootloader yet because I wanted windows too, display resolution fix, etc) leaving whatever would need to restart my machine last, rebooted, and got the same graphics error. That was until I went on the apple forums-
I saw someone had posted about how they had an error exactly like mine-
This is their fix https://discussions.apple.com/thread/6596475
Once I deleted all of those, I restarted, and got the same error. Confused, I looked it up a bit more, and tried this; this was a total gamechanger: msibase=0x90
With that flag, I was able to boot smoothly into my OS, with no hiccups, no GFX errors, etc. I got everything working smoothly, switched my graphics drivers to Nvidia web drivers, and did everything I needed to. With that being said, here is MY boot.plist for MY system. Its def going to be different, unless you're running exactly what I am.
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>EthernetBuiltIn</key> <string>Yes</string> <key>GenerateCStates</key> <string>Yes</string> <key>GeneratePStates</key> <string>Yes</string> <key>GraphicsEnabler</key> <string>No</string> <key>IGPEnabler</key> <string>Yes</string> <key>Kernel Flags</key> <string>-v kext-dev-mode=1 nvda_drv=1 msibase=0x90 npci=0x3000</string> <key>Legacy Logo</key> <string>Yes</string> <key>Timeout</key> <string>2</string> <key>UseKernelCache</key> <string>Yes</string> </dict> </plist>
Oh, after installing win10 on my other partition I simply installed Chimera bootloader, and it works perfectly now. My sound is coming from a blue yeti mic
If you have any other questions, just ask. I'm not on reddit often, but I'll make it a point to come on a bit more.
this was formatted much better when it was in the type box. Sorry if it's a bit hard to read
