Mountain Lion 10.8.5 on VirtualBox

Hello folks

I'm new to Hackintosh, and maybe someone could help me.

I'm trying to install Mountain Lion 10.8.5 (Niresh's release) as a virtual machine on Oracle VirtualBox (version: VirtualBox-5.0.20-106931-Win). The OS on my host machine is WIndows 8.1 x64.

The specs of my machine (I made two screenshots, as my machine is a laptop with dual graphics, in one you can seel the Intel HD graphics card, in the other one the AMD Radeon):


The specs of the virtual machine are as follows:


No matter what I do, it doesn't even finish booting, it always hangs at the following message:


I googled as much as possible, as far as I found out, FakeSMC is responsible for tricking MacOSX into believing it is being installed on a MAC, right? How can that even be that it finds a physical SMC when my computer is definitely not an Apple and on top of that I don't even bott into my physical PC but into a virtual machine?

What I've tried so far:

- disabling my AMD graphics card in device manager (shouldn't be an issue anyway since VirtualBox fakes another graphics card anyway, but who knows...)

- tried booting in safe mode as per your site "Debugging your Hackintosh"

- tried both ncpi=0x3000 / ncpi=0x2000 boot flags

- tried GraphicsEnabler=Yes / No  (both options)

- tried PCIRootUID=1/ PCIRootUID=0

What else could I try?

Treid googling of course, but didn't found a solution to my specific problem, neither on the net in general nor on your page specifically.

Any help is greatly appreciated, and I thank everyone who takes the time to read my post.

Okay, I figured the first step out myself, it's so easy it's almost embarrassing, but I'll leave it here anyway so others who have the same problem can google a solution:

It seems that Oracle tried to program some sort of FakeSMC into VirtualBox themselves, and that their way of doing it somehow is recognized as a physical SMCDevice by FakeSMC.

I just had to change one setting:

Instead of OSX as the guest operating system I just used the generic "Other/Unknown(64bit)" setting VirtualBox offers, and voila, now I can boot into the installer.

Just installing now, let's see how this goes. :)

And here's another point:

I don't really know why, but VirtualBox only needs to be set to "Other/Unkown" for botting from the ISO file. After MacOSX is installed on a virtual hard drive, I even had to change the setting back to "Mountain Lion", or it would hang at boot. But now I got it up and running, only small issues (like keyboard layout) need to be fixed.

Two more things I got fixed:

Mountain Lion didn't recognize the standard Intel network card which is "meulated" by VirtualBox, and I couldn't get it to work, no matter what I tried.


Use the Paravirtualized Network (virtio-net) option in VirtualBox for your guest, and, on the guest, install the following driver:

Also, I didn't get any sound initially, the solution is found here:

Just follow from step 6 on, I didn't need the rest of the steps, as installation of Niresh's ISO worked mostly out of the box (apart from the tiny setting I had to adjust as according to my second and third post).

Things I still couldn't figure out:

Weirdly enough, the resolution is fixed at 1152x864.

I did everything I found on the internet, including putting my desired setting into the



Also, I put my desired settings into the



<key>Kernel Flags</key>

<string>npci=0x3000 darkwake=0 "Graphics Mode"="1680x955x32"</string>

And of course into the VirtualBox settings file:


Does anyone know what I could still try to get my desired screen resolution?

Also, a final problem:

The guest doesn't shut down properly. The VirtualBox Window doesn't close automatically, and VirtualBox keeps on producing a high processor load on the host's processor even half an hour after I have shut the guest down. The guest remains stuck at the following screen:


At least, it doesn't cause any issues, on teh next bootup, MacOSX doesn't "complain" it hasn't been shut down properly.

Still, I'm a perfectionist, any advice on that one?
