Comments

I already owned the whole build. Windows 8 has been on my SSD, everything else (Software, Games, Data) has been on my HDD.

Some day, I decided to get my PC hackintoshed. I like the usability of OS X and how simple it is. It looks fantastic and I also wanted a change.
Couple of years ago I tried to hack my old computer with an AMD Processor and 10.5.8
It was very unstable und slow. And you had to patch a lot.
This time, having an Intel, I started over with Unibeast on a friend’s MacBook.

Install Notes:

If you open up Unibeast, you just follow the Instructions here:
UniBeast: Install OS X Yosemite on Any Supported Intel-based PC

At the „Select Support Options“ Screen, you don't need to select anything.

I think you also could try the Clover Install Guide, but I didn't tested it yet.

UEFI Settings:

You just disable all common things, i don’t think i have to write it down again. After a successful installation, you can turn these things on step-by-step again.
IMPORTANT: This Mainboard seems to have a locked MSR 0xE2 (XPCM) and I couldn’t find the BIOS-Setting to unlock it. If you just try to boot-up Unibeast, it will fail and instantly reboot.
So you have to patch your Kernel - Introductions here: [Guide] Patching the kernel for Haswell CPUs, XCPM early reboot
Be sure to repeat this process after an Update changes the kernel back to stock again. I will provide my kernel for 10.10.3 in the attachements. Just replace kernel in /System/Library/Kernels (MD5 = d89759c11c5f434b4434b6fbf0464d6c)

EDIT: It seems that Clover has a built-in XCPM Patch you need to enable in the config.plist/KernelAndKextPatches/KernelPm option. I didn't tested it yet, they wouldn't provide it if it wouldn't work. You should use the stock kernel though if you're using this patch, I don't know what will happen if you patch a patched kernel

Boot-Flags:

I don’t know why but I had to disable zone poisoning. Just used the no-zp Flag, or it would run in this "a freed zone element has been modified: expected 0xdeadbeef'deadbeef ……" error.
This has been the only boot-flag i needed to make it work. No verbose mode, no safe mode.
After the Installation of Clover, I didn't need this flag anymore.

Clover Configuration for Yosemite
Instead of using Multibeast I used Clover because I wanted everything to be UEFI-Based and enable MSI Fast-Boot.
I installed it on the EFI-Partition (making my Yosemite-Drive look like Vanilla, and actually the system itself is pretty Vanilla, except FakeSMC of course).
On my HDD, I installed Windows 8, just for Programs not available on OS X and for Games performing much better on Windows (although I get decent frame rates on OS X, too)

Surprisingly, everything worked out of the box. Sound, Front-Audio, Video, Ethernet and everything else.
I just cannot make my Lifecam VX-1000 work. But it also doesn't work on genuine Macintosh-Machines.


Boot-Time with Clover and Fastboot Enabled

In the config.plist of Clover I changed the timeout to 0, just for this video to show how fast it boots up.

Normally the timeout is set to 5 seconds, so I can choose between Yosemite and Windows 8.1 (also been installed in EFI-Mode)


Benchmarks:

My Geekbench 3 (Tryout Intel-32) Results: GeekBench 3 Results

Great build. Are you able to use multiple monitors on your GPU?

Thank you!

I don't have a second monitor but if I get a long enough HDMI cable, i could try to hook up my TV. But I'm being optimistic, it even shows the serial number of my Monitor in the System-Info.

As soon as I tested it out, I will update my thread.

Great build, I'm planning to do something similar, how have you done to enable the r9 270x graphic?do you think I can manage to get my r9 280 to work properly?

Thank you, and cheers

With Clover it was detected without adding any kexts or bootflags. It is detected as Radeon HD 7xxx, so will be the R9 280 I guess. But I cannot guarantee. NVIDIA has still better support, but I already owned my GPU.

Hi, I've got the same mobo, but deifferent MSI Slpah Sceen and in my build the MSI fast boot resulted in laggy Clover and boot to Mac OS hung up. Nevermind that, but did you have any issues with sleep mode?
