Yosemite Black Screen after installation, Then Crash on Boot

Recommended Posts


AMD FX 6100 Processor

AMD Radeon HD 6570 Graphics

Gigabyte 78LMT-USB3 Motherboard


The Problem:

After installing Yosemite (Using only /amdfx, npci=0x3000, and -v as boot flags) I get a black screen.


How I've tried fixing it:

I've attempted using the "grafix" Fix on the main forum ( https://www.hackintosh.zone/hackintosh/articles/how-to/fix-grey-screen-black-screen-mac-os-x-installation-hackintosh/ ), But ended up making the whole situation worse.
Now, when i try booting into Yosemite, no matter what I do, I always end up getting stuck at a Yosemite Wallpaper screen, blurred out, then it crashes after about a minute.

I've tried using -x (safe mode), -v (verbose), npci=0x3000 (and 2000), and many others, with no luck.

Keep in mind that it only started crashing on me after I ran the commands as stated on the "Grafix" article. Before that, I was more than likely into Yosemite, Just no working picture on the Monitor.


Please help. I'm not an absolute noob at this, nor am I any expert!


ANY and ALL suggestions will be helpful!



I've attached an image that looks like the one i get right before i get the inevitable crash. The only difference is that there's no Yosemite logo on it.

I did manage to get it somewhat working, after using grafix I boot back into the installer USB and boot from there... the only problem is that now I'm getting stuck half way with "missing Bluetooth controller transport" yet again.

    • Hello. I just installed hackintosh high sierra on my PC. It's version is 10.13 so is there any way I can update to 10.13.3? And also my hackintosh freezes when opening few applications like logic pro x. Please help me.
    • Same problem here. Did you solve this?
    • I was having an issue with installing High Sierra because I was getting this error OsxAptioFix2Drv: starting overrides for /System\Library\CoreServices\boot.efi
      using reloc block: no, hibernate wake: no I tried all the fixes that everyone was telling me about replacing the file with a different one but nothing worked. Finally I came across a post from some person who had a laptop that was designed like mine. I have the Aspire A515-51. The weird thing is that it has 8gb of ram installed. There is 4gb that is soldered to the motherboard and one 4gb ram in the only ram slot. Well this person stated that if he removed the 4gb ram that was installed in the ram slot the install would move past the error and install. I tried it and WOW it worked. I was able to complete the install and everything worked just fine but the wifi. So I hope this helps someone, but I am also hoping that someone can help me with the issue of the ram. I can't add the ram back into the ram slot or the boot will stall at  OsxAptioFix2Drv: starting overrides for /System\Library\CoreServices\boot.efi
      using reloc block: no, hibernate wake: no
