AMD Yosemite Install only boots in safe mode

Question

kyaustad    0

So I used the Niresh Yosemite DMG and TransMac to create a bootable OS X installer. It installed on my clean hard drive no problem. I then try to boot and I can only get a grey progress bar on a grey screen with the boot flag "npci=0x2000" and then the grey bar gets stuck half way. I then used that boot flag and the safe mode boot flag "-x" and I get into the root admin account and used the Niresh login credentials to login. The hackintosh zone ran through setup and optimization or whatever it does. It finished and I cleared network setups and restarted. I tried booting without safe mode and same thing happened. The grey loading bar and then it would stop and I would get the spinning rainbow wheel. I am wondering how I can boot into Yosemite without safe mode and how to use it normally. Here are my specs:

AMD 8 core FX 8320 processor (installed with the /amd boot flag)

Asus M5A97 R2.0 motherboard

8GB ram

Nvidia GeForce 9800 graphics card

Any help is greatly appreciated on how I can get Mac to work normally

Some kext might prevent your system from booting. Boot with -v to see where it's hanging.

When I tried booting with jus -v everything ran through and I didn't notice anything peculiar and it booted to a snowy screen that was basically like television snow. I restarted with npci=0x2000 -v and it booted to a grey screen with the mouse that I can move but nothing else. It doesn't spin even though

Edit: on second look of booting with npci=0x2000 -v I saw one line before the grey screen that raised a hair.

Warning: IOPlatformPluginUtil : getCPUInfo unknown cpu family : family 0x15. Model 0x2

--power management may be incomplete or unsupported

This line appeared shortly but it went to the grey screen eventually.

Enter single user mode (-s) and run 'grafix backup all', reboot and look if it boots up normal. If it does, manually install your graphics kexts from your /backup/graphics kexts/nvidia folder using kext wizard/utility.


the reason why I think that you have problems with (from what I suspect a graphic) kexts, is because it boots fine in safe mode. Safe mode only boots the kexts that are necessary for the main OS X functions.

im still getting the same results with both sets of boot flags. Should I reinstall Kexts in safe mode?

Also in safe mode using kext wizard I can't find that folder. In /system/library/extensions and installed NVDAStartup kext or something like that and using npci=0x2000 -v it booted to login screen! But it doesn't seem as if I can login to my user account but I can login to system admin account using root and Niresh password and username.

Edit again- after doing that I logged out and could log into my user account I created in safe mode. It's glitchy though. Slow animations and stuff so should I use multibeast?

That's not much of a big deal, i've the same because OS X doesn't recognize the 8-core AMD processor. When I set my BIOS to use 4 cores instead of 8 my CPU is seen as a quadcore Xeon.

I'm not quite sure what you mean. What I meant was to use your OS X in single user mode (bootflag -s). It will bring you to a terminal-like environment. From there you can backup all graphics kexts by entering 'grafix backup all'. That command deletes all graphics related kexts from /System/Library/Exsentions/ and places them in /Backup/Graphic Kexts/ (or something similar). If you're able to boot your system without using the bootflag -x, it'd mean that it is indeed a Graphics Kext problem. 

 

You should then only install the graphic kexts (out of your backup directory) needed for your graphics card.

    • Hi guys, managed to make a hackintosh and everything is going great (Wifi, cpu ECT)   But it's pretty damn slow, i tried one of my favorite lightweight games to test (The Ultimate Doom) and it could barely run THAT! This is my first time and i have no idea how to get my 8570 to work.. Probably should have read a bit, eh? Lol.   And no I don't plan on using my hackintosh for gaming, but god so slow..   Thanks, help would be very appreciated. Edit: It's the dedicated version btw, and in about my mac I see "Graphics Display 3 MB" maybe the issue?  
    • Trying to boot to the installer but I get instant reboot after the following: I am using the following flag (I tried a variation - I need USBBusFix=Yes otherwise it fails even earlier): All my USB devices turn off just before it reboots, so I'm guessing it loses connection to the USB install media - but I can't work out why it's disabling all the USB's. My motherboard is an AsRock Killer Fatal1ty 990FX.
    • Saludos!   Tengo el mismo error (RAM a 667mhz), con una placa base ASUS (y mi cpu es el fx 6300).   Lograste solucionarlo?
    • Hi guys. Well, this is my second day of troubles, I touched everything, I installed max like 5 times in the same day, trying to figure out things and well. My Mac it display my graphic card on the #About this Mac tab With 2047MB ( So I guess all is right ) I installed the latest nvida drivers and on clover I activated the NvidaWeb. The problem is the resolution. Max resolution allowed is 1280 x 1024 and 800 x 600. I used to boot with nvd_drv 1 with nvd dry 0, I used to boot with all that things, and without them.  BUT No way to fix the resolution. Someone knows what-s going wrong and how can I fix it? Bdw im using iMac14,2 and OS X Sierra 10.12.3 Im connecting to the screen with DVI adapter. ( Maybe that causes the problem ) But it shows Im running 2047 MB so... idk why I can't change resolution. Thanks! ================================= SOLVED EDIT: Hi guys, in Display Resolution, I just set it in "Default for display" and after that pressing "THE WINDOWS BUTTON KEY, IN MY CASE, IDK WHAT KEY IS THAT IN MAC KEYBOARD, I THINK THE CONTROL ONE OR IDK" PRESSING that key I selected Scaled, and it appears more options and resolutions. There is a video on youtube about that called "Mac OS X Display Resolution" If someone has the same trouble.
