For example, I never encountered it on my Gigabyte GA-Z87N-WIFI BIOS settings, despite using this same CPU. The “CFG Lock” is a setting that is quite new in UEFI BIOS, or appears in some manufacturers.

I personally haven’t tried it, but it’s all over the forums. Later on, if someone really needs it, using kernel flag “dart=0” during boot time seems to solve the issue. Of course, disabling “VT-d” for starters, allows to setup the haxie with minimum of effort and bootloader settings.
#OS X YOSEMITE FOR INTEL AND AMD BOTH CHIPSET MAC OS X#
For Hackintoshes, VT-d is pretty useless virtually no Mac OS X applications use it (virtualization apps like Virtualbox tend to use the alternative VT-x technology, instead), and certain Hackintosh motherboards have been known to crash in Mac OS X when VT-d is enabled. Use this only if you are sure that you need it.ĭisables the VT-d virtualization technology built into certain Intel processors. In any case, recent iterations of Chameleon and Clover allowed to safely bypass this BIOS setting by including dart=0 in the kernel flags and settings. Most of the times, this setting didn’t allow the computer to properly boot OS X, either. I had read somewhere that it’s preferrable to disable Intel’s “VT-d” feature in BIOS (if your CPU supports it) as there doesn’t seem to be any Mac OS X applications that use it. I wasn’t aware of these two settings and how critical they are, for recent generations of motherboards, especially “CFG Lock”. We need to be sure to start from “scratch” so loading the defaults is the first step to every successful Hackintosh. Click on “Settings” button (left, top) to start. Welcome to the main BIOS screen of this motherboard, freshly updated to latest v4.9 firmware. Since I need to keep a record of this for my own reference, too, here is the visual guide of minimal BIOS settings to run OS X via Chameleon or Clover. VISUAL GUIDE TO “MSI Z97i-AC” BIOS SETTINGS Finally, check that “C1E Support” is enabled (check with your CPU specifications).Īfter this handful of changes, go to the main screen and opt to “Save And Reboot” the computer.Check that “Intel C-State” is enabled (check with your CPU specifications).Set to “IGD” as the graphics adapter to initialize (if only using HD Graphics).Disable “Full Screen Logo” option (there’s a good reason for it, I will explain).Disable “Serial (COM) Port” completely (not really needed, but it’s just me).Enable “Extreme Memory Profile (XMP)” to boost performance.Disable “CFG Lock” completely (very critical, won’t boot either).Disable “Intel VT-d Technology” completely (otherwise, OS X won’t boot).

Update to the latest available BIOS from manufacturer!.With some parallel research on my favourite forums, the seemingly typical BIOS settings are really minimal, summarized below: The cooling is performed by a Skythe Ashura, for really silent computing (and some over-clocking, too).Īfter assembly, I booted the computer and went straight to the BIOS update menu, flashed it with latest v4.9 firmware (as found on MSI’s own website). No dedicated graphics card, since I planned to use the embedded Intel HD Graphics 4600 of the CPU (more like a Mac Mini). Additionally, I used again my 2 Corsair Vengeance (Low Profile) memory modules (1600MHz CL9), totalling 16GB of dual-channel RAM (they support Intel XMP v1.3, too). I installed the Intel Core i7-4790K processor (4.0 GHz), hence still in need of a Z97 chipset that can support such unlocked CPU. Please note, it’s not the “Gaming” variant, which costs more (for some reason). The price point and budget allowed me to choose between an ASUS and MSI branded mATX motherboard, so I went for the MSI Z97i-AC board, as it was offering DisplayPort that I really want to check out. Following my failed attempt to setup a stable haxie with my previously purchased Gigabyte GA-Z87N-WIFI motherboard and my fast Haswell CPU, despite other users not having any reported issues (per my search results on the net), I decided to ditch it and go for something different.
