My previous build, Hector (I name my builds), is a H97N WIFI ITX format motherboard which I build to be an entry level enthusiast computer system. However, I found the ITX motherboard didn't have enough PCI slots for my needs. I am a wannabe guitar player who wants to record my practice sessions for later review to determine areas for improvement (usually all areas). But, I found I missed the expansion capability that a PCIe x4 slot provides for a Firewire interface since my external recording adapters use Firewire connectors. So, I decided to return to the mATX motherboard format to get the PCIe x4 slot for my Firewire card. Since Hector was an "entry level" system, this time, I decided to treat myself and get a top of the line mATX. I've never had a ASUS motherboard, and I've heard good things about them from tonymacx86, MacMan, beelzebozo and Gordo74, especially the ASUS MAXIMUS series. Thus, I chose the ASUS ROG MAXIMUS VIII GENE mATX motherboard for my Z170 Skylake build. In addition to the PCIe x4 slot, the GENE has a M.2 slot for either a AHCI (assigned to two SATA ports) or NVMe SSD blade located between the two PCI x 16 slots; hopefully, Apple will support NVMe in the near future. A unique feature of the GENE is the ability to run the system without putting it in a case. The big red button (bottom of the motherboard picture) is the on/off button switch with the Reset button next to it. This feature came in handy when I was bench testing the system before installing the components into the Silverstone case. The GENE also has support for the new USB 3.1, using the ASMedia controller. It has one Rear Panel port in the standard type USB port configuration and one port in the new USB 3.1 Type 3 configuration. The rest of the real panel USB ports are Intel chipset supported USB 3.0 ports. Another feature is the ability to update the BIOS from within the BIOS using the Internet to grab the updated BIOS and install it. Nice. However, the feature I used to update the BIOS is called the USB BIOS Flashback (page 2-12 of the GENE User's Guide) which allows updating "the BIOS without entering the existing BIOS or operating system." Here's the simple instructions from the User's Guide: To use USB BIOS Flashback: Download the latest BIOS from the ASUS website. Extract and rename the BIOS image le to M8G.CAP. Copy M8G.CAP to the root directory of your USB storage device. Turn off the system and connect the USB storage device to the USB BIOS Flashback port. Press the USB BIOS Flashback button. Oh!...and another subtle, but extremely nice piece in the motherboard set of accessories is the Front Panel "ASUS Q-Connector which is a removable Front Panel plug that lets you connect the case's Front Panel connectors (wires) without all the inconvenience of trying it directly on the motherboard itself. Once all the wires are connected, then it's only a single plug to orient on the motherboard's Front Panel header. Finally, the GENE is just good looking with red lighting even when the computer has been shutdown. If I've piqued your interest, then I recommend you go to the GENE web page for a description in great detail. The rest of the components Speaking of red, I chose the Corsair Vengeance LPX because of my great experience with the Corsair Vengeance LP White memory kits in my Z68 based systems. Well, low & behold, the LPX comes in colors including red. Well, I couldn't pass up red memory sticks for a motherboard with red accents. However, most important, the Vengeance LPX is on the GENE's Memory Qualified Vendors List. I chose the Samsung 950 Pro M.2 NVMe SSD for two reasons: first, the motherboard had an M.2 NVMe slot and, second, since I determined the M.2 NVMe SSDs were the wave of the future, I wanted to test it. It works with RehabMans's patch which is needed (see below) because Apple is using a modified version of the NVMe standard, go figure. Update: The Samsung 950 Pro has been superseded by the 960 Pro which is faster. The 950 Pro is $60 USD more expensive than the 960 Pro on Amazon. So, go for the 960 Pro. Speaking of good performance, I chose the Gigabyte GeForce GTX 950 based upon the operating performance of Hector's Gigabyte GeForce GTX 750 Ti. Why didn't I get a GTX 960 or 970? Well, I don't play the popular, graphics demanding games nor am I getting a 4K monitor anytime soon. But, surprisingly, I read in one of the GTX 950 reviews that the OC 950's can meet the performance of an entry level 960. (See the Tom's Hardware review.) OK...sold! One last word...I chose the Gigabyte brand because I've 1) learned years ago that Gigabyte is in the first tier of graphics cards and 2) Gigabyte's designs tend to support four (4) monitors on their cards. Since I use dual monitors, this is worth the $10 USD more than the cheapest GTX 950. So, another for the Gigabyte GeForce GTX 950. One of the best kept secrets in the Mac world is the Logitech Solar K760 Bluetooth keyboard for the Mac. It uses normal light to charge it's internal batteries and has 3 separate Bluetooth "assignment" keys. This later feature means you can assign the keyboard to three separate Bluetooth devices including computer(s), iPad and/or iPhone. Nice. I also really like this keyboard because I'm a touch typist and I like the typing feel of this board. But, the real beauty of the K760 is that it works from the start of boot up to get you into and around in the BIOS. However, you have to have the right WiF/BT4 PCIe card like the one I have that uses an iMac BCM94360CD chipset. You do have to "wake up" the K760 as you boot up by tapping the fn-delete key if you want to get into the BIOS or use the keyboard in the Clover boot screen. Get an Apple Bluetooth Magic Mouse, too; you won't regret it. Now for the SilverStone SST-PS07B mATX case. I like it very much now that the system is assembled. But, it was a pain to get the components into the case. Step 1, take off the side panels. Step 2, unscrew the top of the case and remove (!). Step 3, remove the motherboard tray(!). Three hours later, after installing the SSD, then the PSU, next the motherboard scans the graphics card... Oh, I had to remove the HDD removal tray because the case's USB 3 header cable interfered with motherboard's header location and the HDD tray. (I finally got the HDD tray back in but I hope I didn't stress the motherboard header plug too much.) Once the graphics card was installed and the cables routed to maximize good airflow, the case looked like everything fit as if it was designed to contain my components. For such a highly praised case (in all the reviews I read), I'm not too impressed. It is light, and it fits on a desk without taking over the desk. But, I've been spoiled by the Fractcal Design Define series and Lian Li mATX cases. (Think I'm going to look into the Bitfenix Phenom M case about which tonymacx86 raves. Of course, the Phenom M costs twice as much as the SilverStone - hope for a sale soon.) Just recently, I acquired a Other World Computing USB-C Dock in anticipation of getting a Skylake MacBook Pro this year. So, I decided to try out the Dock on the GENE using the Rear Panel's USB 3.1 Type-C port. It works using Rehabman's USB kexts and the Clover config.plist modifications description in the Installation section of the post. However, it only works at USB 3.0 speeds. The true be told, I only have a USB 3.0 thumb drive, so that's the speed limit that I can report. However, I am getting connectivity and USB 3.0 speeds using the USB 3.1 Type C port. See post #117 for the AJA benchmark. The Installation Since a build description is more about the build component selection than an installation guide, I'm going to only hit the essentials of the installation which are only peculiar to the GENE. The following assumes you've got all your components installed in the computer system's case. For installing El Capitan, see [Guide] Installing El Capitan on ASUS MAXIMUS VIII GENE - i5-6600K - Gigabyte GTX 950 The following is a fresh install for Sierra. If you've already have El Capitan installed, see this post for updating to Sierra. If you are updating Sierra to 10.12.4, you must first update Clover to version r4045 or newer; do this first > See my post here for updating to Sierra 10.12.4. If you are updating to Sierra 10.12.5, see Post #970. Making the UniBeast USB Thumb Drive Use the tonymacx86 guide UniBeast: Install OS X Sierra on Any Supported Intel-based PC. Note: your USB Thumb drive needs to have 7.63 GB of free space to build the UniBeast installation thumb drive. Otherwise, you'll need a 16GB USB thumb drive which is a better size so you can load the following applications for use in the post installation phase: MultiBeast for Sierra which you can probably put on a 8GB USB thumb drive, but a 16GB drive is best EFI Mounter V3 KextBeast For proper processor power management, get the SSDT for your processor from ammulder's Guide and rename it SSDT.aml; I chose the SSDT for my i5-6600K. Note: ammulder's SSDTs are for non overclocking speeds; for overclocking, you'll need to create a SSDT for your processor using PikeRalpha's ssdtPRGen.sh script located here. Rehabman's Codec Commander kext for making the audio (after wakeup from sleep) work which we'll install using KextBeast Clover Configurator for fine tuning (Optional) the nVidia Web drivers for the Maxwell chipset cards (750, 750 Ti, 950 Ti, etc). See tonymacx86's sticky thread in the Graphics forum section or the tonymacx86 driver list. (Optional) If you are using the M.2 SSD slot with a NVMe SSD, then get the RehabMan's patcher script. However, after making the UniBeast USB Installer Thumb Drive, you'll need to either use my modified USB Installation Thumb Drive's config.plist or do the following to the USB Installation Thumb Drive: Insert the UniBeast USB installer thumb drive to a working USB 2 Back Panel Port; Open the Terminal and run the following: Code (Text): diskutil list Note the UniBeast USB drive's EFI partition's "diskXs1" designation - could be something like "disk0s1"; Use EFI Mounter Version 3 to mount the UniBeast USB drive's EFI partition; Navigate to EFI > EFI > CLOVER folder; Open another tab in your Finder window and navigate to Download/patch-nvme-master/ folder You're now going copy only the KextsToPatch patches in the NVMe_patches_10_12_4.plist, starting with: Code (Text): ... <key>KernelAndKextPatches</key> <dict> <key>KextsToPatch</key> <array> <dict> <key>Comment</key> <string>IONVMeFamily IONameMatch</string> <key>Disabled</key> ... to Code (Text): ... <dict> <key>Comment</key> <string>IONVMeFamily Pike R.

Make sure your tags match up, then save the config.plist file for the USB Installer Thumb Drive and close the NVMe_patches_10_12_4.plist file. Note: the above shows a range of patches, not the entire set of patches. Close the USB Installer Thumb Drive's EFI Finder window and Eject just the EFI drive in the Desktop window.BIOS Setup Follow Step 3 in the tonymacx86 guide. Update the BIOS to the latest version which is 2202 as of October 04, 2016. If you're without a working computer, do it on a friend's computer and follow the USB BIOS Flashback method on page 2-12 of the GENE User's Guide. Note: BIOS versions greater than 2202 will no longer save NVRAM (important) between boot ups. This impacts iMessage and Nvidia web drivers. So, if your BIOS version is greater than 2201, you will need to fix this in MultiBeast as I point out below. Once the BIOS is updated, boot into the BIOS, use the Advanced Mode and make the following changes: Extreme Tweeker AI Overclocker Tuner > X.M.P. Extreme Tweeking > EnableAdvanced Items System Agent (SA) Configuration > VT-d > Disable PCH Configuration > IOAPIC 24-119 > Disabled USB Configuration > Legacy USB Support > Auto USB Configuration > XHCI Hand Off > Enabled APM Configuration > Power on by PCI - E/PCI > DisabledBoot Menu Fast Boot > Disabled Boot Logo Display > Disabled Secure Boot > OS Type > Other OS Boot Option 1 > USB installer thumb drive (the UEFI choice if there are two entries) Exit > Save Changes Installation Notes If you are installing Sierra over El Capitan, do the following before proceeding to the next steps: Update all your apps so you are current with El Capitan. Backup your El Capitan installation disk. I use Carbon Copy Cloner. Follow Steps 4 & 5 in the tonymacx86 guide: UniBeast: Install macOS Sierra on Any Supported Intel-based PC. But, Insert the UniBeast USB Thumb Drive in the USB port in the bottom USB port at the bottom of the stack with the PS/2 port at the top (see Rear Port graphic above); Boot into the Sierra Installer with the UniBeast Installer USB thumb drive to begin the installation. (Optional) If you have a current nVidia graphics card, then Boot with nv_disable=1 (spacebar at the Clover boot screen) until you install the nVidia web drivers; When the Part 2 install process ask you to log into iCloud, do not log in - skip it - as it messes up Messages; Drag & drop MultiBeast and Codec Commander zip files from the thumb drive to your Applications folder, unzip them, run MultiBeast and selection the following: Quick Start > UEFI Boot Mode Drivers > Audio > Realtek ALC1150 Drivers > Audio > 100/200 Series Audio (Optional) Drivers > Disk > 3rd Party SATA (Optional) Drivers > Misc > FakeSMC Plugins (Optional) Drivers > Misc > FakeSMC HWMonitor Application Drivers > Network > Intel > IntelMausiEthernet Drivers > USB > Increase Max Port Limit (and adds RehabMan's USBInjectAll.kext) (Optional) Bootloaders -> Clover v2.4k r4063 UEFI Boot Mode + Emulated NVRAM <--- Required if BIOS version is greater than 2202 (Optional) Customize -> Graphics Configuration -> NVIDIA Web Drivers Boot Flag <--- Required for use of Nvidia drivers Build <--- To see your full configuration Note: The default System Definition is the iMac14,2 for Sierra. I recommend you use this SysDef to do your installation and get Sierra up and running. You can change it later if need be. Save <--- Save your MultiBeast configuration file somewhere convenient Click on the Install button in the MultiBeast window bottom right hand corner and wait for MultiBeast to finish. Important. MultiBeast v9.1.0's FakeSMC Plugins' FakeSMC_GPUSensors.kext has not been updated to support Pascal graphics cards. To prevent Kernel Panics and Reboot Open the installation drive's /Library/Extensions/ folder; Find and trash the FakeSMC_GPUSensors.kext; Delete the Trash._ (Optional) If you have a current Nvidia graphics card, copy the Nviida driver from the thumb drive onto your Desktop, unzip it and install the driver now, but don't reboot when the installer is done, just leave it along as we'll come back to it. Drag & drop the Codec Commander zip file from the thumb drive onto your Desktop and un-zip the file. Drag the CodecCommand.kext from the Release folder to the Desktop. Drag the zip & the two folders to the Trash. Drag & drop the KextBeast on your Desktop, unzip it and run it; chose to put the kexts in the /Library/Extensions/ folder (/L/E/). Drag and drop the CodecCommand.kext to a safe place. Now you need to install your processor's SSDT.aml (if your EFI partition is mount from doing the Nvidia mod above, then skip the first three steps): Open the Terminal and run the following: Code (Text): diskutil list Note the Sierra drive's EFI partition's "diskXs1" designation - could be something like "disk1s1"; Run EFI Mounter v3 to mount the UniBeast USB drive's EFI partition; Navigate to EFI > EFI > CLOVER > ACPI > patched folder; Drag & drop the SSDT.aml from the thumb drive ino the ...ACPI > patched folder._ (Optional) If you are using the M.2 SSD slot with a NVMe SSD, then you need to create RehabMan's patched kext and spoof SSDT. You'll install the kext in your installation drive's /L/E/ folder using KextBeast: Create your spoofing SSDT using Rehabman's [Guide] HackrNVMeFamily co-existence with IONVMeFamily using class-code spoof. Note: I'm not going to post my SSDT-NVMe-Pcc.aml as you need to learn to create your own SSDT-NVMe-Pcc.aml. However, see my posts Here and RehabMan's response in the next post for the SSDT's parameter for the GENE (and only the VIII GENE motherboard). Install the SSDT-NVMe-Pcc.aml in the EFI > EFI > CLOVER > ACPI > patched folder as you did with your processor SSDT. No need to rename the SSDT-NVMe-Pcc.aml. Assuming your patch-nvme-master folder is in the your Downloads folder, run the following Terminal commands: Code (Text): cd ~/Downloads/patch-nvme-master ./patch_nvme.sh--spoof 10_12_4 Drag the HackrNVMeFamily-10_12_4.kext from the Downloads/patch-nvme-master/ folder to the Desktop. Make sure that only the HackrNVMeFamily-10_12_4.kext is the only kext on your Desktop. Run KextBeast and select the /L/E/ folder to put the HackrNVMeFamily-10_12_4.kext. Remove this kext from the Desktop to another folder or your USB drive._ Now click on the Restart button in the Nvidia Web Driver window or reboot the computer if you didn't install the Nvidia drivers. Reboot into the BIOS. Change BOOT > Boot Options Priorities > Select your installation disk to either the: UEFI (Samsung 950 Pro...) NVMe M.2 drive or UEFI setting for the Sierra drive. Note: Always pick the UEFI choice if there are two entries for the same drive. EXIT to save the BIOS update and reboot. Due to a quirk with Apple's cache (see the Note in MultiBeast v9.1.0 Announcement), you'll need to rerun MultiBeast v9.1.0 selecting only the following: Drivers > Audio > Realtek ALC1150 Drivers > Audio > 100/200 Series Audio Build > Install Reboot after installation is complete To get audio working you'll need to use the Green sound port on the Rear Panel with the System Preference's Sound pane set up as follows: Finally, since we're using the iMac14,2 system definition, we have to make one more change since Sierra broke wake-up from long (4+hours) sleep. Special thanks to pastrychief for discovering this "fix"; see his Build Description and Post #63 in his Build Description thread for more details. So, in the Terminal, execute the following command: Code (Text): sudo pmset -a autopoweroff 0 See also my Post #557 in MyHero Build Description thread for a summary of pastrychief's explanation. One last tip/note, to check to see if your SSDTs are loading, use the following command in the Terminal: Code (Text): bdmesg|grep -y aml You can also add this to your .profile in your user folder so that, upon opening the Terminal, it shows the results. USB Charging RehabMan has a guide to allow USB 3 ports to charge iDevices. Rather than repeat it here, see Post #971 for the details on adding a DSDT patch in the config.plist. Welcome to Clover and Sierra! Summary This hackintosh is fantastic! Enjoy your hackintosh. What Works USB 3.1 ports work, but at USB 3.0 speeds. The USB 3.1 Type C connect must be inserted at the Clover boot screen and disconnected after shutdown or at reboot because, somehow, the BIOS won't boot with it plugged in. Sleep & Wake-up, both manual (Apple > Sleep) and scheduled (Energy Saver SysPerf pane). Wake-up takes about 15-20 seconds to complete while CodexCommander does its thing. USB 3.0 ports charging iDevices. Audio through the Green back panel port. Audio works after sleep/wake-up with the Codec Commander kext. iMessages Continuity/Handoff with the Boardcom iMac WiFi/BT4 PCIe card listed in the Components section at the top of this Build Description What Doesn't Work Everything works that I've tried.
