Using it for Xcode and Adobe Software for the most. Used Bitterlemon's build as a Guide: http://www.tonymacx86.com/golden-bu...ip-build-ga-z77n-wifi-i5-3570k-hd-6870-a.html After assembling the components into the case, I set the BIOS using this guide: http://www.tonymacx86.com/99-quick-g...55-boards.html This is a build without use of DSDT. This build went so smooth, much smother than i imagined! Thinking about adding a 7xxx AMD Card when/if they are fully supported. I chose the XFX 550W PSU in the last minute. My first Option was a cheap Corsair, but then i saw the new XFX PSUs is build with Seasonic components, and the price was about the same. i'm glad i did because its small and quiet! Installation Step 1 - BIOS - First Load Optimized Defaults - Set your Hardrive boot order to the P0: option (not UEFI) Under Peripherals: xHCI Mode = AUTO xHCI Hand-off = Enabled EHCI Hand-off = Enabled Init Display = IGFX (if HD 4000) VRAM = 64mb Under Power Management: High Precision Event Timer = Enabled Power on by Keyboard = Any Key Power on by Mouse = Move Wake on LAN = Disabled (May not be there.) Bios Features: Intel Virtualization Technology = Enabled VT-d = Disabled (ignore this if you have the Z77N-Wifi) Overclock Configuration: Extreme Memory Profile (XMP) = Profile 1 (to run at 1600 MHz) change Turbo radio to 42 on all cores. (The Z77N-WIFI motherboard is NOT a great OC board max on 3570K was 4.2 stable.) - Save & Exit Step 2 - Unibeast Follow this guide here http://tonymacx86.blogspot.dk/2011/10/unibeast-install-mac-os-x-lion-using.html (you can put your DSDT file, Updates and Chimera installer in here as well.) - Hit F12 to boot from USB - Boot from Unibeast USB dongle (If you can’t get to the installer try with –v or –x –v) - Format your drive. - Install OSX Mountain Lion to your newly formatted Drive. Step 3 – 10.8.3 - Install Update 10.8.3. - Reboot machine. - Boot on to Unibeast USB drive. - Boot into OSX Mountain Lion . Step 4 – MultiBeast - Start the latest MultiBeast. Choose the following settings: 1. UserDSDT or DSDT-free installation 2. driver & bootloaders – drivers – audio – without DSDT – Realtek ALC8xx - ALC892 3. driver & bootloaders – drivers – network – Realtek AppleRTL8169Ethernet 4. Customization – Boot Options – 1080p Display Info! Choose “driver & bootloaders – drivers – audio – with DSDT – Realtek ALC8xx - ALC892” if you have DSDT and want HDMI Audio (but be aware, you lose Sleep Functions.) - Reboot when all installations are done. - Boot on to Unibeast USB drive. - Boot into OSX Mountain Lion . Step 5 – Chimera - Download and install latest Chimera. - Reboot - Now it should boot Mountain Lion without the Unibeast USB Drive.

Summary and Notes UPDATE: 21/11-2014 - Installed "Antipop" to remove pop sound when Sound goes to sleep. Installed "Sound Siphon" to control HDMI Audio volume (Genies! way better than the outdated SoundFlower app). UPDATE: 20/11-2014 - Made a custom DSDT and SSDT with many series7 fixes and enabled Nvidia/HD4000 HDMI sound, changed to Mac mini 6.2 for better speedstep - Changed Realtek ethernet driver to the new RTL8111 v.1.2.2. - ATTACHED MY DSDT & SSDT FILES (Remember that SSDT is running 4.2GHz) UPDATE: 12/05-2014 - Added a Zotac Nvidia GTX660 2gb - worked out of the box. UPDATE: 06/06-2013 - Installed Realtek - AppleRTL8169Ethernet instead of the Lnx2mac's one, to eliminate an network error, where it would'nt reconnect if IP was lost, due to router restart. UPDATE: 29/03-2013 - Been using this build for a week now, and no big problems so far, there is some small things i would like to make better. Fully Working: OS X Mountain Lion 10.8.3 Intel HD4000 All Audio Jacks Ethernet Connection (port #2 ) All USB 3.0 ports (full 3.0 speed with 3.0 devices) after DSDT, Ipads now charge via USB.
